By far the best video I've seen on this procedure, hell this might be the best video I've seen on any auto repair! After watching a few others I didn't want any part of this repair but now I feel like it's no problem. Ordering the parts now.
Exactly what I was thinking. Other videos seemed a bit vague and didnt get close up enough. Basically just seems like dissabmely and assembly. I have the parts on the way and going to take a whack at it when they get here
i have to agree with you 100%
I have everything and was taking it to a mechanic! But scrap that! While I'm at it I'm doing my throttle body and alternator
BIG HELP !
💖THANK-YOU For This GREAT Video !!!💖
This video is much better than the A1-Auto video
Thank you very much! We try our best to help everyone really Fear No Fix!
Total mechanic newbie but knocked this replacement out of the park yesterday. Couldn't have done it without these gents and this superbly made video. Cheers!!
Just did mine today while watching this video step by step. Really helped a lot. Not that hard of a job, just a lot to take loose. I did go a step further and put new intake gaskets in and permatex around the covers on knock sensors. Thanks for the video
Not at all - it looks like a handful up front but take your time and most people should be able to do it
Thanks guys. I'm about to perform this exact repair on my 5.3 and you have by far the most clear and thorough step by step guide I've found so far with the best camera angles too. I will most certainly be referring to this as I work. One other detail worth mentioning is that GM has a technical service bulletin out about the knock sensor replacement. They recommend removing the foam seal on the rear side of the intake manifold visible at 14:25 in the video upon re-installation. This is to allow any intruding water to easily drain out the back. Also, they suggest placing a dam of RTV sealant around each knock sensor hole with a small opening facing the rear of the engine to further prevent water intrusion. Cheers.
Thanks for the tip! I'll be doing this to my 5.3 this weekend.
Thank you so much. Great Information . Planning to do my repair tomorrow. Thanks to BlueDriver and your advise.
swapped out the oil pressure sensor and intake manifold gaskets while I was at it and really cleaned the block being careful nothing got in those holes and even then, took me about 3 hours. just pausing a playing the video going step by step! you guys are amazing!
Love how y’all went step by step I’ve never really worked on cars but with this video I was able to replace my 01 silverados , thanks guys
While you have the intake off, consider replacing the oil pressure sensor. Especially if it’s pegging out at max.
Dude great idea. I didn't even think of that.
I agree, and also the filter under the sensor. You need a 1=1/16 socket 6 point.
@@jamesdumez8022were is this filter located on wich sensor?
Might as well do the cam sensor to.
👍🏽 did it myself no issues. Recommend replacing wire harness.
3 steps. Thumbs up. Subscribed. Click bell icon. I gotta do this job on my '02 5.3L Silverado. I've been watching dozens of "how to" videos for the last 2 weeks and I must say that this video is hands down the BEST VIDEO on this subject. Thanks. Great camera work. Love the tools needed section. Love the "44 steps" step by step description. Chris in Boulder CO USA.
She's a long one, but completely doable!
except for that kink in the evap line, seal the knock sensor in place, AND he didn't clean off the mating surfaces.
Really can’t thank you guys enough! Saved me a ton of cash. It sucked for sure, but I wouldn’t have attempted it without your guidance. Kudos fellas. Nice of you to take the time to do this!
Very welcome Jay! Glad we could be of help! Fear No Fix!
great Video guys.no annoying music no crap talking.
will be doing this on my 01 Denali XL 6.0 . looks pretty simple.
miss the old days when you could remove a intake and replace in no time.
Thank you guys for a very informative video. After watching a couple of times I was able to get this job done in just under 4hrs. Not to bad for a carpenter. Top notch step by step instructions. Thanks again!!
These guys are great!!! I just used their list of steps to work on my Yukon. I checked off the list step by step so I didn't forget anything. It went great!! Thank you so much for a great video and I loved the check list. You guys rock!!
Very detailed step by step, would recommend replacing the gasket and both seals where the knock sensor sits while you’re there if anyone is doing this repair
I just performed this repair on my 2005 Suburban 1500 LT 5.3L. Took about 2 hours start to finish. This video was exactly what I needed! I took my laptop to the shop, watched some of the video, paused, then performed the task. At first I was fearing the fix, but after I got into it, it flowed like milk-n-honey. I did use some Red RTV Gasket Maker on the knock sensor wiring harness rubber gasket. I also replaced the manifold gasket. You guys did a great job with this video! Fear no fix!
Nowhere near as bad as it looks, is it!
This video was by far one of the most useful. It gave me the confidence to get that job done. Many thanks for the money saved and lesson learned
Absolutely fantastic video!! I watched a few other videos prior to finding your video and was beginning to consider sending the truck to a shop for the repair. After watching your video a couple of times, I felt a great deal more comfortable and tackled the project in about 3 1/2 hours. I highly recommend this video to anyone attempting this repair!
This is a great video. I have watched several videos on replacing the knock sensors. Your video had all the fine details and very well explained to make the job easier for someone to do this. I really like that you explained the socket sizes needed and torque specs. Saves someone time digging thru the tool box and trying sockets to find the size and saves time looking up the torque specs. I'm about to do this job shortly on my truck. Thanks.
Thanks for all the info. I finished my 2005 Sierra 5.3 today. No codes! Just take your time and follow the directions and take your time and you'll be fine
I just did this repair today it took me just under 6 hours. Well worth the time to do it myself. Had to remove the valley cover for the back knock sensor was rusted on tight so I had more work added. After I was all done my truck runs so much better. Made a big difference in engine performance. Still need to get the code cleared. Thanks for the informative video.
If this sensor goes bad, does it cause a no start to the engine? Cranks but doesn't start?
@@Ryan_1997No
These mechanical jobs always look easy until you do it yourself.
Really ? For me they always seem complicated until I find the RIGHT video and jump in. Once I'm in there it's all quite simple. Just a matter of having all the proper tools really.
@@rosieanciola3685 every car and truck is different. You never know what problem they might give you when fixing something?
But I agree with you. After watching 100 videos you will start to get it.
@@rosieanciola3685 I totally agree.
15 mm Wrench
15 mm socket and Ratchet
8 mm 1/4" swivel socket
1/4" Extension 12" long
Electric ratchet 1/4 drive
GM fuel coupler disconnect tool ( The only special tool you need)
Pry bar and hammer
Needle nose pliers and 90 degree pick
22 mm socket, Extension and ratchet
And 50 minutes to get the job done.
@@tedfox2683 yes. I've rebuilt most of my tranny on my 2000 Jeep Grand Cherokee and the hardest parts were when I was trying to force a tool to work on something it wasn't meant to 🤦🏽♀️
Factual
Video really helped, what didn't help was when I snapped off the fitting behind the throttle body, then had a literal rats nest under my manifold, and then I had to pull the lift plate to get to the back knock sensor and then had to use a special extractor tool because it was rusted to shit. But, I really do appreciate yall.
Oh my! Glad we could of at least helped you get it done!
My knock sensors and PCM are in process of being replaced. This really helped me to appreciate where all the labor costs go to for the sensors. WHAT A PAIN IN THE REAR! Thanks so much!
Thanks so much for this video. I was not wanting to pay to have this fixed, but the job seemed daunting. It wasn’t simple, but your video seriously helped so I could do it. I did replace the manifold gaskets, cleaned out the throttle body, replaced the knock sensor gaskets in the valley pan, replaced the valley pan gasket, and also replaced the oil pressure sensor.
love the video 🙌🙌but the way he handled the evap line 😭😭😭we know damn well our shit gone snap if we do some bending like that 💀💀💀
Really good video. I like the detail but also concise. - I've got the P0332 code and will be doing this job shortly. 2005 GMC Yukon XL SLT 5.3L (311,000 miles original engine and transmission) My only comment is a me thing. I would never put it back together without cleaning everything - especially the valley pan and other stuff not normally accessible. Nice job.
Great video, my friend and I followed it step-by-step on his '04 Suburban 5.3L and were very successful, almost couldn't believe how well it went.
This is the second time that I have used this video to replace the knock sensors. Thank you, guys, so much. I am hoping that I never have to do it again. Plus, all in all, with your help in the video it took me back to the days when I loved working with cars, most of all my 41 Chevy Special Deluxe Coupe. Thanks again for the detailed video, it will give confidence to those that might not have all the courage to jump into this type of project. 3/19/2022
I just completed this repair on a 2006 Tahoe. This video was spot on and really helped me to understand the proper techniques. After purchasing the sensors and a few tools, I completed the job in about 3 hours, including a few breaks. The rear connectors on the injectors were a real bitch. I would recommend disconnecting the negative terminal of the battery to be safe.
Very detailed. Video was long, but it's the best long video I've seen. The instruction was clear and precise. Can't wait to perform this task. Thanks.
Chris & Jim, thanks for making this video. In parts and tools I spent $100. I was nervous going into this but the clear-cut video made it easy. Replaced my sensors and in my part of the country and the rough quote I had I was looking at a $1,000 repair. My ‘04 Chevy Tahoe is running great and gained horsepower by fixing the sensor. All ready for summer vacation with the money I saved!
Did u really torque the bolts down?
Such a great video. Step by step, easy to follow, straight to the point. THANK YOU, from a single mom tired of going to mechanics who either cause more problems then before or overcharge me for everyyything. I was able to do this project with my Dad, if we didn't get stuck on a rusted knock sensor this probably would have only taken 3-4 hours. So kudos to you guys for making a comprehensible video! THANK YOU!
This video helped me get the job done in under 2 hrs. Yay!
Best video I have seen on the task at hand! Very impressive. Thank you!
Superb video. I will probably have to tackle this job soon on my '04 Silverado. (DTC but no check engine lite). I am so thankful you guys took the time to explain it all in such perfect detail and with nothing unnecessary (unlike so many videos). Thanks again - great job!
Honestly never work on my cars and just by watching this video step by step I was able to complete this repair! Thanks
I'm tackling mine next weekend! Your video gives me the confidence to do it. And step by step instructions! Thanks a ton.
This the real deal here. Was thinking on taking it to a shop, since i don't have too many tools. But after watching this, i'm just gonna buy what I need and do it myself. Awesome video.
Screw the thumbs down.
Thank you guys for knowledge. Just got done doing this project on my 2000 Chevy Silverado. Really not a bad job. Did everything like you suggested and turned out great. You are great in detail and recommend this video for anybody with one of these older Silverados or vehicle with the 5.3 vortec. Thanks for your help. God bless.😊
Great video, and step by step guide. Feeling much more confident about tackling this repair this weekend! DYI on my friends!
Thanks guys...my son and I did this repair this weekend only because you did such a good jog on this video.
OMG!!! Your video has been THE BEST so far with changing out the knock sensor. I have a 2003 Chevy Suburban and I changed out some parts and this is my last one to do. I believe in saving money and you helped me save it. Time to get to work. Thank you guys for this AWESOME video and yes I definitely subscribed to your channel.
I watched the video once before starting to change the knock sensors by myself. Was able to get the job done in under 1.5 hours. Great video.
Not as bad as it looks is it!
@@LemurMonitors Not at all.
I was in deed looking for a solution to my knock sensor problem. Your video is extremely helpful and nicely detailed. Thank You Blue Driver.com. I will recommend you to my mechanic friends.
Nice and informant. I had a few other items on my 2001 5.3. ERG line and throttle/cruse cables. Service engine light still on.
I'll for information to clear. That was a lot of work. You guys really helped me out.
Nice job,great video guys ! I have 05 Yukon 90,000 miles..No current issues..
You guys are Amazing Very informative and helped me fix my sensors without missing any step.
Pretty similar I’m doing 03 2500 with 6.0 and I been watching videos for a week and this helped me breathe and go into it fully assured to fix , I had to remove the foam piece in the rear of my intake and do some RTV to divert the water for future.
I gotta do it to my 03 k2500 burban 6.0..
Best detailed video I've ever seen! Still a little intimidating but at least you guys gave me hope! Keep up the good work 👍
It looks scary but give it an afternoon to do, take it one step at a time and there's nothing to it.
Thank you for sharing your knowledge with us! This video was definitely a money saver! I was able to do this procedure with no complications.! 👏🏼👏🏼👏🏼
Great video, very helpful in replacing the knock sensors in my 2003 Silverado.
Great video! Really helpful! Got it done in four and a half hours!
Thanks for this post is was a vital part of me getting my knock sensor replaced the right way.
Happy to help!
Hey guys going to do this on my Tahoe 2005...this weekend guys this is going to help bigtimes...thanks...keep rocking...7/13/2020....San Antonio TX
Great video guys; even my wife was impressed. I did change my intake gaskets because they " crushed" unevenly on one or two intake ports and i thought it would be prudent to go ahead and change them. I did have to clean a lot in that area since i have 263,000 miles on it . thanks for a great video.
Thanks for this video. Just finished up both sensors and the harness on my truck. Looked really intimidating until i watched your video. 1.5 hours and done.
Did you buy 2 of the same sensor or are they different?
Thank you guys from Navajo Nation!
Thanks guys, followed this one for my 1st time removing the manifold on an ls. Found tons of oil in the manny but didnt have the ls6 valley cover to fix it for good. Plan to pop her open again down the road, cant wait to cut my time in half!
Thank You! Hey, don't forget to put the Fuel Pump Relay back in. Have used the AC Relay for the Fuel Pump Relay in a pinch.
took me a while but I did it. thank you guys so much best video of auto repair i’ve ever seen to be honest.
That's awesome, thanks for the feedback and happy we could help!
Great video, it helped me a lot with my 2007 Silverado classic only difference was injector harness. I did have an issue where the rear knockout sensor was rusted. I wasn't even able to put a ratchet on it. It got so bad where the top was basically missing. It only left the knockout sensor body walls and threads to the engine. I ended up removing the "valley" so I can remove the rear sensor. Besides the rusted sensor this video was very helpful. I would recommend to add RTV sealant to prevent water to get in the sensors. Again great Video!
This video was great! I might suggest that the camshaft position sensor should have been replaced while you were that far into it. I am about to embark on this very project this week and I will definitely be referring to this video. Thank you so much. You made this look easy.
Definitely emphasis needed on INCH POUNDS for the intake manifold bolts. First one I set to 44 ft lbs like a complete dummy because I wasn't paying attention enough and sheared it right off. Yay!
Thanks so much for this video!! I just bought a new to me (used) 05 Sierra 1500 and this code came up the next day. Your video was excellent and I got the sensors changed in a day along with the spark plugs.
Awesome! Glad we could help!
Hey guys, awesome video!!! Just completed this procedure on my 2001 GMC 5.3. The video and explanations were excellent!!! Thank you very much. Joe Colon, Tucson, AZ.
Question! Was the ticking more from the top of the engine or bottom??
Hey me to Tucson az haha
awesome video. Truly appreciate the breakdown, step by step. It was super easy to do this what seemed to be intimidating job while watching this video. Thanks guys! I'll be back!
My truck is nearing 150xxx miles and when I torqued on the intake manifokd bolts I had one break off inside of the header. Recommend new intake manifold bolts for this repair. It was so much getting that out without ruining my head! Bolts were factory OEM bolts and this happened on the lower torque first pass. Careful!
Great video! Very clear and precise. Just don’t forget to plug back your fuel pump relay.
Friendly tip. If you do this its wise to replace the harness at the same time. Over time the heat cycling of the wires can make them brittle. It would be a shame to have to do this again because a wire broke a month or 2 later. Also I highly recommend to stick with AC delco sensors
Good call
@@LemurMonitors i just did the job for the 2nd time. each time i used this video as a guide.... even though i probably didnt need to haha. its a pretty straight forward job. i did it over a saturday and sunday, affording myself to thoroughly clean the grease and grime off the engine block and valve covers. engine looks a lot newer than 140k haha
I caught the Canadian accent the first time you said: out! Great video!!!
Throttle cable, cruise control cable and fuel pump relay. When you start let fuel pressure build first. I would have cleaned all the surfaces, siliconed the covers replaced the harness and gaskets. Great video maybe even the best one out their. Thanks.
Thank you!
thiis is a fantastic video explained extremely well, i just pulled this code i will take the weekend to do this job thank you for this video
Amazing video. Took me all afternoon but I feel very accomplished. Thank you so much. I look forward to more videos to fix more.
Thank you for the video, its very clear and professional.
Great video. it really filled in the missing gaps.
Glad we could help!
To bad you guy didnt get to the head gaskets. I'm starting my head job tomorrow. Your videos are super useful and well done.
Wouldn't mind seeing that video either. If you make one let us know!
Thank you bluedriver. I had a heck of a time doing this job. And I wouldn't have been able to do it if not for this video. You showing how to properly remove the fuel injection plugs really helped. I have an 02 4.8 tahoe and the hardest part was those dang coolant hose clamps on the throttle body. Getting them off and putting them back on was about 2 hours of labor😣. Next time I'm taking your advice on the special hose clamp pliers👍🏼
Worth every cent!
I just performed this on my 2004 silverado, hardest part was removing the fuel line (becuase i didnt have the special tools) and disconnecting the 2 hoses under the throttle body. other than that it was allot of fun and easy, re assembally is even more fun and allot easier than disassembly.
One part in this video i saw was to prevent future corrosion to that back knock sensor is remove a small foam piece in the back top of the intake manifold.
I don’t comment on YT videos but DAMN. Best video out there. I’ve never had more than the intake tube off of this truck before and I just swapped out both sensors, harness, and gaskets in less than 2 hours. Watched this video and printed your PDF guide and I was set. Having a tool list was great too. Thanks guys. Keep it up!! Dummies like me depend on you.
The sensors you just buy 2 of the same one?
Where did you find the harness? Did you find an AC delco one? And how do you install it?
Brad Menezes Fishing O’Reilly Auto had it all in stock for me. No issues since swapping them. Make sure to build up a dam with the silicone crap!
@@STMFC so you were able to get all the AC Delco parts from oreilly including the intake manifold gasket, 2 knock sensors and the knock sensor wiring harness?
Brad Menezes Fishing yep!
Wow....great video......you guys are the real deal..can't thank you enough
very informative I followed your instructions and did it in the 2.5 hours!! thanks guys!
Not as bad as it looks is it?
Never done this before so this is super helpful. I’ll let you know how it goes in a couple days.
Good luck!
Thanks for sharing. Saved me hundreds of dollars doing it myself.
But you did replace the gasket. I just watched the same video but edited for knock sensors. Sneaky sneaky! 😂 these videos do help alot though. Thank you!
Very Helpful Video, got me and my buddy through. My sierra is in better shape now 👏🏽
Worth saying, whole you have the manifold off, replace your oil pressure sensor while it is easily accessible.
LOL... I am a mechanic myself and when I have a good size job I'm doing I like to review the procedure in the book or on youtube. Most CZcams vids are long winded with people talking about their kids Birthday or a history of peanut butter or some other long unneccesary yaking.
Your video was to the point and professional. Thank you thank you thank you.
Nothing worse than having the scan around trying to find the part that actually matters
Absolute awesome video guys.
Watched video first, very informational and helpful! Took4 hours,only problem I ordered the parts from Amazingzon!Great coverage!👍
Fear no Fix 👏👏❗❗❗
The best video ever thanks for taking the time 👍
This guys are Great..saved me a ton of money..thank u fella appreciate
Thank you guys I am fixed up so far so good
Just did my sensors today and it was much easier than it seems. This vid was great as I just paused after each step. I did add the silicon to the boots to help keep moisture off of the sensors. Oh and don’t use a big torque wrench, I snapped a bolt with mine.
I found that the rear sensor was rusted badly and wonder if this is the same issue others are finding.
Awesome video! Thanks guys 😁
This video was a life saver thank you.
Happy we could help!
Great video! Mahalo. I use Bluedriver as a scan tool and it is also incredible.
Very informative, thank you for this video.
For anyone doing this still. Look into the service bulletin that GM put out for removing the rear foam block from the intake manifold and sealing around the covers with RTV silicone to prevent the back one corroding again.
