My current truck has 237,000 miles and is still running great. Hope to keep it that way a lot longer. Thanks!
I watched this video before I did my 2007 Colorado. It was a great help, thanks for the video.
Fantastic! Glad to help. 👍👍😀
To clean the throttle body you should take it off and clean the other side which is the side that gets dirty. The side you showed in the video doesn’t usually get very dirty. It’s the other side that gets gunked up with carbon and causes some idling issues.
Thanks! Have never taken the throttle body off on one of these trucks. At 210k miles I should probably do that one of these days, LOL. 🤣
Question, my PCV hose came undone from the intake.... How the hell do I get that plastic cover off so that I can see what I am doing?!
Great video man. Only thing I wish was you had video of actually performing the replacements. But I definitely learned a lot. Thank you.
Thanks man! I try to talk through and explain the entire process. It's kind of hard to turn wrenches and hold a camera at the same time. 😆 Was there something you weren't able to follow?
That said, this video is quite a few years old. We bought a house in 2020 with a garage, so no more wrenching in the parking lot and I can make better videos. 😁
I swear since I've starting watching ur channal I never bring my 06 colorado to a mechanic unless I absoulutley have too. Keep posting brother !!
I will be following this guidance in my 2005 Colorado tomorrow. Thanks.
You're welcome! Glad to help. Let us know how it goes. 😊
My dad has a 3.5l 2004 brand new. Has 230k on it. Been a really good truck except for the passlock. If it didnt crank and start he would have to wait 10 min before it would start. Finally got it fixed. His colorado has been a good truck.
Hi Darjin! Thanks for checking out my video and for the comment. Glad to hear your dad has been keeping up with the maintenance and that your truck is still running so well.
You're right, Passlock is a very common issue on the 1st generation Colorado/Canyon platform. I had mine tuned out when it first started acting up around a decade ago (sent my PCM off to "PCM of NC" to have it tuned out - called "VATS delete"). Never had a problem with it since. Definitely recommend it, if you have trouble with yours again in the future. 😊
Funny I found this comment a coworker of mine had a stroke about a year or 2 ago and he's getting ready to sell his 2005 canyon and he's offering it to me it has 210k miles he's always had a local shop do work on it so it's fairly well taken care of he says there's nothing major wrong with it but he did mention that sometimes it won't start so he'll wait 10 or 15 minutes and it'll start up. You mention you guy's got it fixed what did you do to fix it? Would you guy's recommend this truck? I really want a first gen tacoma but those things are going for some serious money that I don't have at the moment and I can't really pass on this deal as a truck is something that's always needed.
@Darjan_Spasojevic my 2011 Canyon does the same thing. I found a video of a work around so you don't have to wait 10 minutes.
Decades of doing car repairs in parking lots. I'm so glad my wife and I bought a house with garage in May 2020. Hopefully my more recent and future videos will be much better than this one. ☺️
Hey Mike I hope you can maybe help me out here. I'm doing a spark plug change and when I got to the 5th cylinder I put my socket it and it just spins, doesn't seat down as far as needed. My set up has worked with all other 4 cylinders, what could be wrong I feel like a dimwit. There is indeed a plug in the cylinder.
@@iFrostiy Hi! Thanks for the comment. It sounds like you know what you're doing. Could there be something lodged in the socket, maybe, preventing it from fully contacting the plug? My spark plug sockets have a rubber "bushing" (for lack of a better word) inside them to prevent them from dinging the top of the plug. Sometimes that slips out of place. Maybe stick your pinky finger up inside the socket and see if maybe you have that, and it's slipped down?
Only other thought would be if someone stuck a radically different-size spark plug in there and you need to use a different size socket, but I doubt that is the case.
Check for the rubber thing and let me know. I just did another plug change on my '07 a couple weeks ago. 231,000 miles and still running great. Good luck with yours!
Great video! Changed my plugs with no problem.
Awesome! Glad to help. 😊
@@CompTechMike I am still trying to figure out rough start and lack of power sometimes and your video was the simplest I ran across. Keep up the good work!
Mike thanks so much for your video and it is excellent 👍 !!!! I'm going to help my buddy do a tune-up on his 2002 Colorado. When he told me it had five cylinders I thought..."no way"? So, look it up on CZcams your video came up 🙂 !!! Your approach, filming and step by step clarity is top shelf🏆and very thorough 💯. I liked all your suggestions to clean the map sensor and throttle- body. Replacing the springs that connect to the spark plugs ...great idea (how big and where'd you buy them?). Thats probably better than using dielectric gel. Now I know exactly what to do and what to expect. You deserve the 👑 and 🎯❤ for brightening up 🌞 my day with your high octane ⛽⚡ explanation to accomplish this job🔥 precisely... So, thanks again🙏. I want to do a video soon and I hope I can do one as well as you have. It's truly been a pleasure🏝🛻 !!!
Come to think of it... the sound and the visual was so good what did you use to record this ?.... if you don't mind my asking.
Your video is really very interesting from a practical and creative perspective 👌 !!!!
Hi! You're welcome. Glad this video was helpful. It was just recorded with a cell phone - a Google Pixel 3 XL. You might want to verify the year vehicle you are working on. Chevy did not make a 2002 Colorado. For more info on the SuperSparkz check out this thread:

Nice! Hope it gives you many years of good service.
Great video thanks!

I did a tune up on a 2004 colorado with the 3.5 i5. Ran into several issues. When i finished the 3.5 was replaced with a mildly built L76 6.0
The 3.5 definitely has some problems. I prefer the 3.7 or 5.3 in these 1st gen trucks. But obviously if you can afford a 6.0, go for it! Sounds like a nice truck now. 😊
Nothing gets done without coffee in my world.

It's also good for the Izuzu i370.. thank u very much.!
You're welcome! Glad to help. 😊
Have you had issues with replacing TPMS sensors and them not having the two final chirps after pairing?
Hi! Good question. It's been years since I had to do this. If I recall correctly, the biggest problem I had was defective sensors. Had to replace a couple but afterwards had no further issues. Have you tried the procedure listed below (and in the links)?
1. Turn ON the ignition, with the engine OFF.
2. Apply the parking brake.
3. Turn the exterior lamp switch from OFF to parking lamps 4 times within 4 seconds. A double horn chirp will sound and the low tire pressure indicator will begin to flash indicating the learn mode has been enabled.

There isn't any town named chevy in colorado , I checked
Excellent tutorial thank you
You're welcome! Glad to help. 😊
Just did the plugs on my 08 Colorado yesterday. 268,00+ miles on it and it didn't look like they had ever been done before. lol Idk what number owner I am but I know that I'm not the first.The truck came from Louisiana and end up in New Hampshire where I bought it with an after market fiberglass AstroBody Box on it instead of the pickup bed. Runs a lot better now but I don't think it's up to 100%, though. I think it's a fuel problem but I'm not sure.
Nice! Great work keeping it running. Maybe run a little Sea Foam through there? At that many miles you may need a fuel filter, which unfortunately is inside the tank in our model trucks. Are you getting any CEL's? Good luck!
@@CompTechMike How do I do that? Do you have any videos on it or that you can recommend? It's giving me a couple of codes but I've already replaced both of the recommended parts.
@@luigiprovencher8888 Hi! Thanks for the comment. I do have a video on using Sea Foam. It's about 9 years old now but may still be helpful to you:
czcams.com/video/V7fv-Fg1hKU/video.html
I'm sure there's a lot of other information about this process out there on the web including forums like 355 Nation and Colorado Fans websites. :-)
Unfortunately I don't have a video for changing the fuel filter, however if you suspect there is a fuel problem dropping the tank and cleaning it out, and replacing the filter (especially after 268k miles) is probably a good idea.
Thanks for making this video with your Colorado have you had some issues with the ignition switch or lock pass security code where you have to wait to start the vehicle after about 15 minutes?
Hi! Thanks for the comment. Glad the video is helpful. 🙂
The issue you are describing is called "Passlock". Passlock is a rudimentary anti-theft system installed in all 1st generation Colorado's, Canyons, and their variants (Hummer, Isuzu). It is a problematic system that has been discussed to death in the forums and will eventually fail on 100% of 1st generation trucks. The way it works is, it uses a sensor inside the ignition cylinder to detect theft attempts. When it engages it "thinks the vehicle is being stolen" and it disables the fuel pump for 10 minutes, preventing the truck from starting. You'll get light on your dashboard with a lock symbol and a "crank no-start" situation - the engine will crank but won't be able to start because the fuel pump has been disabled.
Note - if your truck does not crank at all it's not Passlock. If it doesn't crank at all suggest checking battery, cables, grounds, fuses, ignition cylinder, or starter - in that order.
When Passlock fails (and it will fail, eventually) there are three common solutions. You can either replace the module (but eventually it will fail again), you can cut a wire under the dash, or you can have it disabled with a tune ("VATS Delete"). Most tune shops that work on our trucks are able to do this. If you do not have a local tuner you can remove your PCM and send it off to a company like "PCM of NC". That's what I did way back in 2014 when mine first started acting up. No problems starting since, and I also had them do things like adjust for tire size and remove the speed limiter.
Hope this information helps. Here's a few additional links:

Side note: Some vehicles specifically manufactured in Canada may have PassKey instead of Passlock. This was only for a year or two and only on Canada-manufactured vehicles.
100% right on the $ Mike also thanks for making your videos of the Colorado stuff under the hood and all around they have been VERY HELPFUL and EDUCATIONAL 👍🏽👍🏽
@@CompTechMike I did the "cut the wire" method on mine about 10 years ago. I know people are hesitant to do something like that, but I works great. I still drive the truck daily. I just put compatible connectors on each piece of wire in case it ever needs to be reconnected for some reason. You have to live with the light on in the dash, but this way is a simple "fix".
@@shawnknoblauch6338 Thanks for the comment! Glad this video is still helping people. Yes, the "cut the wire" method is definitely the fastest/cheapest. Especially common "beater" trucks. Personally I had mine tuned out, but that was a lot more expense that may not be worth it on trucks that are generally 15+ years old now. 🤷😆

Great video, nicely done
Thanks! Glad it was helpful. 😃
I’ve had 3 Colorado crew cabs with a 3.5. (2005). I’ve had issues with the drivers side window. Could it be a grounding issue? All 3 did the same thing!
Hi Richard! Thanks for checking out my Colorado videos. When you say "I've had issues with the drivers side window", what issue are you referring to, specifically?
That said, yes, grounding issues are very common in these Colorado's. There are two grounding blocks under the hood (one located on the inside fender roughly near the battery, and the other on the opposite side by the air filter box) that frequently cause trouble. One suggestion is to disassemble them and clean them, scuff a bit of paint off where they bolt (so they can make better contact), or you could replace them with a standard bolt and ring terminals. There are also ground points along the frame that can become loose or corroded over time and are worth inspecting.
Besides that, I know those switches in the door can go bad. I've had to replace a few of them myself. Look for replacement switches from a reputable seller like RockAuto.com; I've had "hit-or-miss" luck buying cheap ones off sites like eBay & Amazon. Dust, water, and other stuff coming in through the window, as well as frequent use, are culprits for these switches wearing out. You can start by checking and wiggling connections or using electrical contact cleaner spray.
A third point to check is the rubber passage between the door and body of the vehicle. All the wires run through that narrow path and can become pinched or worn over time.
Of course there are also mechanical points of failure such as the motor, regulator, fuse, or relay.
Obviously without seeing the vehicle it's tough to say for sure, but hopefully this list of things to check will get you started. I'd also recommend looking on forums like ColoradoFans.com, 355nation.net, and the Facebook group "Chevy Colorado & Canyon (First Gen) Fan And Owner Page". Hope this helps, good luck!
Great job 👏 well explained 👏
Thanks! 😊
Great video love it! I also love that grill guard you have on there. Where did you buy that?
Hi! Thanks for your comment. I got it on ebay back when I first got the truck, I believe it's called a "Truck Gear Direct" "Hunter". I've been in four accidents with deer in earlier trucks, a couple of them at 60mph. After the first one did $4,000 worth of damage I started putting these on; the last deer that jumped in front of me only managed to bend a piece of the guard and knock out a headlight. Much less damage thanks to these guards. Definitely recommend!
FYI- Never use anti seize on the newer spark plugs, they already have it from the factory. You can throw off torque Specs and damage the head.
Good tip, thanks! Guess it was more important 30-something years ago. 😉
Another great video
Thank you! Glad it was helpful for you.
Have you researched the benefits of changing out the ignition coils? I know you mention here a performance spring upgrade, but what about a 5 coil replacement simply because of age? Do you think they degrade in performance over time (lower voltage or less spark) - or is a coil simply either functional or non-functional so maintenance change out is not worth it?
I haven't researched it, but definitely agree that this part could deteriorate with age.

Alright Mike so I’m wondering if you can possible help me. Before changing my spark plugs my truck did not have a check engine light. I replaced my spark plugs at 99,500 miles. I used AC Delco iridium plugs properly gapped to spec. Soon after driving with the new plugs the CEL came on. Now when I was changing the plugs cylinder 2 had oil all in the spark plug well. So that lead to me getting the valve cover gasket, tube seals, and intake manifold gasket replaced. Today I just replaced the upstream and downstream o2 sensors. I recently just cleaned the throttle body, map sensor, and MAF sensor. My truck idles at 600 RPM. The code that was scanned at Autozone was P0420 something relating to the catalytic converter. I have had all this work done and the CEL is still on. It’s driving me insane. Please if you could try and help me I would appreciate it. 2008 Colorado 3.7L 4x4.
Hi Andrew! P0420 in a Chevy Colorado often indicates an issue with the O2 sensors or catalytic converter. It sounds like you're doing all the right troubleshooting steps, but I'd suggest the following:
(1) Get your own code scanner. Clear the code and verify if it still comes back again. If so, after how long before it comes back on?
(2) Get a scanner that's able to read real time data. Verify that it's showing data coming off the O2 sensors. I'm not suggesting you be able to understand the data (although this wouldn't hurt), but just be able to confirm that the truck's computer is showing data coming from the sensors. It could be a loose or damaged wire or connector causing the truck to not "see" the sensor, if that makes sense?
(3) Double check your part numbers. I usually recommend a site like RockAuto. There's always the slight possibility that Autozone sold you the wrong parts, or that you received defective parts (this goes back to being able to see if there's data coming into the computer from the sensors).
(4) Inspect for exhaust leaks. It's pretty common for the exhaust manifold on the Colorado to develop cracks over time. Listen and feel around the exhaust for any indications of a leak. Follow the pipes back to where they connect to the two catalytic converters for any leaks or breaks. Be careful not to touch - **hot!**
(5) Any bad smells coming from the truck? A failed catalytic converter is usually described as smelling like "rotten eggs". 99k miles is pretty low, but we are talking about a 15-year-old truck, after all.
So I'd start with those things. Verify that if you clear the code, it comes back. Verify the replacement sensors are sending data. Check for bad wiring, possibly a bad or defective part, and check for exhaust leaks.
You can also check out this article for suggestions:

If you're still having trouble I recommend forums like 355nation.net and coloradofans.com, and also the Facebook group "Chevy Colorado & Canyon (First Gen) Fan And Owner Page":

Good luck, if you find the solution come back and let us know. Thanks!
@@CompTechMike first of all thanks for the quick reply. I got this truck actually one year ago on this day. The first thing I did was replace the exhaust manifold and gasket. Not the cheap one that comes with it but one from GM dealer that I had to special order. I noticed there was a vacuum leak coming from the manifold area so that’s why I replaced it. No weird smell that I can smell when I drive it. Or when I’m outside of it with it idling. When I replaced the o2 sensors today I disconnected the battery which got rid of the CEL. When I put everything back together and started it for the first time the CEL was gone. I drove maybe 5 miles and then I saw the CEL come back on. Yea a scanner would be nice, but they are expensive. Also the spark plugs that I used were AC Delco 41-103. The o2 sensors I used are the exact same part numbers you used in your video. I also got them from rock auto.
@@CompTechMike I just checked for exhaust leaks, and there is a leak by the exhaust manifold in the same area there was before I replaced the manifold a year ago. Same exact spot. However I never had a CEL when there was that leak with the old manifold.
@@Andrew-Knecht Hey, that's great news! Well, not "great", but at least it sounds like you've figured out the cause of your CEL. It definitely sounds like you're following the right process. I'd still recommend getting a code scanner when you're able. Sounds like you won't need it for this repair, but maybe for the next one. These Colorado's really like to through emissions & fuel system codes. 😆
Did you have any problems with the bolts when you replaced the manifold before? It's pretty common for the bolts to break and then be a pain to extract. Good luck, hope this is an "easy" fix for you!
@@CompTechMike I was very careful with the manifold bolts and used a trick from a guy on CZcams so they do not break. All bolts came out completely fine and not broken. I’m not going to mess with the manifold again, because really I don’t see the point in doing that work again. Like I said the CEL was never on even with that same exact trouble area. So messing with the leak again will not help with that issue. It’s too much work for no real gain or not much gain. CEL only came on after replacing spark plugs which I did because owners manual says 100k to replace so I did exactly that. I don’t know man it’s just frustrating. I have spent at least 3k fixing replacing old parts, and I don’t want to mess with the truck anymore.
I have a question does your truck have the Traction Control button or no? My 09 3.7L extended cab 4wd does with the g80 3.73s 1LT
Hi! Thanks for the comment. Mine is 4WD with the G80 and no traction control button. I vaguely recall it was an option on 2WD trucks with the locker, but from this thread sounds like there's a few 4WD trucks (like yours) that got it, as well:

Where are the intake sensor wires connected? I bought a Hummer this week and the sensor is there, but the connector with the wires are gone. The old owner must have disappeared with him, I don't know. I would like to know the path of the sensor wire input to its final destination. Thank you
Hi! Thanks for your comment. When you say "the intake sensor wires" which sensor do you mean, specifically? There are several. Depending on what engine you have and what year, they may be in different locations.
I recommend the following videos for more information on the various sensors. As I mentioned before, mine is an '07 with the i5 engine. Yours may be slightly different. Hope these links help show the locations of some of the various sensors:

The MAF, MAP, camshaft position sensors, and VVT solenoid are some common "sensors" you may need to replace on a 1st gen. Other common sensors include the oil pressure sensor and crankshaft position sensor. Those are both much lower, located on the passenger's side and the driver's side of the block, respectively. However they are not typically referred to as "intake sensors". I think you're looking for one of the above (in the links). If you'd like to comment back with more specifics of your particular vehicle I may have more suggestions for you. Good luck!
@@CompTechMike Mine is a 2009 3.7 hummer. Problem is, my Camshaft Position Sensor Intake is not plugged in anywhere. Someone cut the sensor wires, I already opened the entire electrical harness of the vehicle and I can't find where this sensor could be connected. I'm from Brazil and here we have few Hummers, nobody knows the electrical installation of this vehicle. If you can help me I would be very grateful. Knowing where the wire that connects the sensor goes so I can find where to connect it to its final destination... Thank you.
@@thiagolemao hi! Do you have one camshaft position sensor on the engine or two? Look very carefully. In 2004-2007 the engines had two camshaft position sensors. In 2008 and up they only had one sensor. It's a very common problem that people ask "where do I plug in the second sensor" when they do an engine swap from a truck with a newer engine to an older, or vice versa.
Is it possible that someone swapped the engine in your vehicle with an earlier engine? You may only have one wire but two sensors, depending on what year the donor engine came from. Unfortunately I can't help much beyond this, but I know the issue with the sensors is very common in swapped motors.
Are you getting any check engine codes? Which ones?
@@CompTechMike Your information gave me a lot, it was very Immensely grateful! My engine has never been changed, it's the same one that came out in the original 2009 vehicle. But for some reason my engine has 2 sensors, one on the passenger side that always exists and another close to the alternator that is in the engine but without any wires connected to it. This made me look for the connector all over the electrical harness, but I didn't find it and the reason you just explained to me. For some reason my 2009 hummer must have said it had 2 sensors from the factory, but the driver's side is not connected to the electrical part, it only serves to cover a hole in the engine where there should be a screw. Immensely grateful. In need of something from Brazil, you can count on a friend. Thanks.
@@thiagolemao you're welcome! Glad to help. I just double-checked on Rockauto.com and they only list a single camshaft position sensor for the 2009 Hummer H3 with the I5 engine. So it sounds like as you theorize, for whatever reason instead of having a plug, yours has that second vestigial sensor. Assuming the truck is running well and not throwing any codes, I wouldn't worry about it. Sounds like it's just a plug. 😊
Does anyone knows what would the right torque for the spark plugs? I'm about to replace mine this week and wouldn't like to damage the tread.
Hi! Thanks for the comment. 13 ft/lbs on torque is a good starting point, but I suggest you look up the exact specs for your engine and year. They may be different for your particular vehicle. Coloradofans.com and 355nation are good sources, as well as the various Facebook groups. 😊

For a 2010 the spark plug gap for the Ac Delco plugs are .040
Good tip. Depending on the type of plug you install, they may or may not need to be re-gapped.
@@CompTechMike I made the mistake of taking my Chevy van to a mechanic sometime later after that it started running bad even blowing smoke out the back.... Finally, it came down to they didn't have the right spark plug gap !!!... it was too close and fouled the plugs. Never again !!!
@@Raymond-rr5iv Better to do it yourself. That way you know it's done right. 😁👍👍
@@CompTechMike for sure !!! Recently, I bought a 2018 Kia Sedona with a "essentials package"... and it's killing the battery. It ran great for two weeks and then I had to replace battery ( went to AutoZone they check it, charging system and starter were just fine...dead cell in the battery). So...new battery and two days later dead battery again. Went to AutoZone again and this time everything checks out good. I'm trying to track down the power drain. The key fob won't open up the sliding door either but it opens and closes normally with a slight door tug and closes normally pressing the "close button" on the van body. I'm thinking maybe a bad solenoid that receives impulse signals from the key fob ? Now, I have to disconnect the battery cables every night til I solve the problem. Any ideas? In one of your responses you suggested a "Chevy Colorado Truck Club". I'm wondering if they have one for the Kia Sedonas ? Thanks again....and You have a variety of interesting videos !!!
Curious. After so many miles have you ever changed the coils?
Hi! That's a great question! Guess I've been pretty lucky. I'm at 235,255 miles now and never had a code or issue with my coils. I recall seeing a few years ago something called "Supersparkz" that would replace the springs in the coils with solid metal and thought about doing something similar at the time, but (fingers crossed, knock on wood and all that), I've never had any issues with them.
Of course, now that I say something, they'll probably go bad next week. 😉 How many miles do you have on yours? Any major issues?
@@CompTechMike Just coming up on 100K. Prior to me owning it, It was a park ranger truck in Ohio. Great service record but how many idling hours is unknown. Want to change the plugs and was concerned that when I pulled the coils it might mess them up. A set of aftermarket coils are pretty cheap, so I was considering changing them at the same time. Biggest problem is rocker panels are cancerous. I'm getting quotes of 3K. Yikes! Never was into body work. A set of replacement panels are only about$150.
@@michmvp yikes! That's cool that you know the history. I think you should be okay to re-use the existing coils if you want to save money, but since you need to remove them anyway it's as good a time as any to replace. 😉
That rust can be pretty bad on our trucks. The rockers, as you noted, I'd also check around the back of the frame near the leaf springs. Boxed frame can trap water (no drain holes in bottom) and rust from the inside out. Good luck, hope she gives you many more miles!
Good job!
Thanks! This video is a few years old. Truck has over 238,000 miles on it now and is still running great! 😊
5 spark plugs?
Yes, it's an I5 (inline five cylinder) engine. 😊
@@CompTechMike cool
Are these 3.7 engines good, reliability wise, any major problems?
Hi! Thanks for commenting on my video. I might be a little bit biased, but mine has worked great. 215k miles and no major issues beyond the usual maintenance and wear parts. Nothing I couldn't fix myself. The 3.7 solved many of the major problems with the head the earlier 3.5 engines had, and was a solid engine in many of the GM vehicles of this time period.
@@CompTechMike OK great thanks, awesome video btw 👍

Will those plugs work on the 2004 3.5 i5?
Hello! Thanks for commenting on my video. Yes, according to Rock Auto, the 2004 3.5L engine also can use the ACDelco 41-103 plugs. It looks like they have a manufacturer rebate going on right now, as well:

@@CompTechMike you rock!
Do you have a video for changing the gas filter, i have a 2004 gmc canyon
Hi! I'm afraid I don't have a video for that, but on an '04 it should be pretty easy to do. The fuel filter is located inline of the fuel lines running up towards the front of the vehicle, usually near the left side (driver's side) near the parking brake cables. Once you slide underneath just feel for the lines around the tank and follow them up, should be pretty easy to locate. You may need a couple open end wrenches or pliers to undo the disconnects. Keep a bucket and rags underneath to catch any spills. Also, take the fuel cap off first can help remove some of the pressure from the system, making it less likely to drip.
You're lucky, after '06-'07 they started putting the fuel filter inside the tank. Only way to change it on the newer trucks is to drop the tank and pull the pump. That or remove the bed so you can reach it from the top! 😫😭😭
@@CompTechMike ok thanks
awesome video. can you do one on compression check. thanks.
Thanks! Great suggestion. I haven't done a compression test in many years. Maybe time to do one again. ;-) Thank you!
@@CompTechMike hey I have a 2007 Colorado 4 cylinder 2.9 and when I drive it it starts to shake and turns completely off what you think it is I change battery is not that nor the computer nor the throttle body control sensor what you think it is I also change the oxygen sensor but no luck
@@CompTechMike also thanks for the video keep up the great work I subscribe
@@AlejandroP1980s Thanks! Sorry for the slow response, CZcams didn't send me a notification for your comment. Did you ever get this worked out? Are you getting any check engine codes? If you are, I'd start there. One other common problem to check for that can cause these problems is the VVT sensor. It has screens that can fall out and clog the engine oil passagways. Read up on that, it's a pretty common problem. Good luck!
@@CompTechMike ok thanks
Where is the egr valve at on the 3.7L
Hi! These trucks don't have an EGR valve. They have the Variable Valve Timing (VVT) on the exhaust cam to accomplish the same emissions results.
@@CompTechMike oh ok
Is this the same procedure for a 2009?
It should be, assuming you have the same i5 3.7L engine. There were very few changes between 1st gen model years. As far as I know the biggest change between your '09 and the '07 in this video is bigger brakes. If you do find anything else different related to this procedure, let us know. Thanks!
@@CompTechMike Sad to say mine is completely different. Do you know of any videos for my vehicle?
@@mkdsk101 I'm curious how is it different? What engine do you have?
@@mkdsk101 You can try other videos like this one. If you have the 4-cylinder or the V8 engine, or some kind of aftermarket air intake, is pretty much the only differences you are most likely to encounter:

@@CompTechMike It is a V8 abd I can send you pictures if you have a way to email them to you.
Coffee!!!
Yasss! 😆🍵☕
Owners manual says the gap is .040”.
Hi Andrew! Thanks for checking out my video. I try not to give specifics like this because the 1st generation Colorado trucks had six different engine options between 2004-2012. The measurements may not be the same for each of them. I just show the process, always recommend people consult with their owner's manual for exact specifications of their specific vehicle.
That said, assuming you are using high quality replacement plugs, they recommend not gapping them because the iridium center electrode is more brittle than most metals and can be fractured or broken.
The ground electrode (the hooked one) is actually platinum and can be bent carefully, but to be honest I’d just leave them be. They should be preset. Measure before install. If one is significantly off, return or exchange it. 😊
@@CompTechMike I understand. They were all different gaps for me, and I gapped them to .040 carefully. Hopefully everything works well after.
السلام عليكم شنو مشكلة الدخن الابيض
I'm sorry, I don't understand your question.
Decades of doing car repairs in parking lots. I'm so glad my wife and I bought a house with garage in May 2020. Hopefully my more recent and future videos will be much better than this one. ☺️
