- This 2007 Ram 3500 with a 6.7 Cummins is running hot and the A/C isn't working. The fan clutch has been replaced but it's still not working correctly.

Lots of questions about the air hammer tool. It's this one from Lisle: amzn.to/3bSd7SI
Thanks Wes.
Came to ask this; found pinned answer. Top quality service, 5* would use again.
College roommate was watching that part with me. "How the F is he taking a fan off with an air hammer?!?" haha
You read my mind. This was the question I had after viewing this video. I was in the same situation sans the correct tools and I damn near made a pact with Satan to complete this job.
What scan tool is that?
The electro-viscous fan clutch (yes, that's the name) basically just replaces the little bimetallic doodad that purely mechanical fan clutches have with a solenoid. Internally the clutches still work the same. Solenoid opens up, allowing the silicone fluid to enter in the "friction" area at a controlled rate.
"what if we take the worst aspects of a mechanicL fan clutch, and the worst aspects of an electric fan and combine them together" - engineer, somewhere.
Useless tech. Why not use a regular electric fan?
@@dmitryhwguy1646 electric fan can't move enough air to keep a diesel cool, the big engines are all belt driven fans as well.........
@@randallvos That's BS, modern fans have enough power to lift clean off the table. Brushless. New world tech.
@@aserta I guess the complication might be amp draw. How many amps at 12v would it take an electric fan to match the output of that big mechanical one, especially under resistance, and for how long of a duty cycle with heat etc?
Trailblazers had a super annoying version of this kind of fan. Doing water pumps on them was tricky, mostly because removing the fan was fiddly and annoying.
Way back in the day I bought a used Chevy Chevette. After a month or two the starter quit. The mechanic got a rebuilt one and put it in, It worked for about a week. This process repeated 5 times. He told me only rebuilt starters were available. Since the rebuild shop was local he called them. The original owner had sold out about six months before and the new owner was doing what is typical, cutting costs everywhere he can, which included hiring unqualified help. Anyway, my mechanic talked the old owner into overseeing the starter rebuild and lo and behold that starter was still working fine when I sold the car a year later. Shows to go ya, there is no substitute for knowing what you're doing.
No matter how much experience you get, your only one thought away from putting a spanner or wrench across some battery terminals. Thanks for the great content Wes, genuinely look forward to them.
I did that in my auto tech vocational school in 2008... melted the 2 posts and I still have the wrench. Instructor said he never seen anyone make a face like I did but will never do that again. Lol. Haven't done it since. Sadly, I still put stuff on the battery... it's a flat surface for nuts and bolts lol but I do try to keep wrenches off the battery.
@@Jarhead64 For a flat, go-anywhere surface for nuts/bolts/etc, get yourself a couple of those magnetic trays. You keep that stuff off the battery, with the added plus of not knocking small parts down into Never See It Again Land.
@@billh230 I did then I set the tray on the battery.
@@billh230 where's the fun in that. Hahaha
*You’re only. Not your.
FordTechMakulco is a good guy to watch too. He is so talented with Fords that he gets customers from all over the US, which limits the number of videos he can make. In one instance the Ford dealer wanted to replace a customer's engine when the only thing wrong was a bad electrical connector under the hood. Great work Wes. Thanks for the video.
Max doesn't say much but his looks and body language make up for it. Great dog.
Wife-proof. Pure gold Wes. Pure gold. 😁
hell at least he's got his mowing the grass.
I don’t laugh very often , but did! Thanks Wes.
That'll stop her from curbing the wheels on the work truck
Mrs. Wes either does not watch the videos, is happy about the amount of money these videos bring in, or is a stunt double, either way, she is a keeper, the only question is are YOU a keeper?
Wife proof? Just keep the truck dirty. I get eew this is gross I'm not getting in that truck until you clean it
Eric O cracked me up calling the three peddles a _Millenium anti-theft device._
*Thank You* for the videos Wes. They are greatly appreciated. 👍
*pedals *millenial
@@PJBonoVox Thanks Phil. I appreciate the corrections. 👍
just like "compuders" are an anti-boomer device!!!
@@tomhgeary I'd better remove my Systems Engineer qualification from the wall then. Ah yeah, me is a boomer. 🤦♂
Our family has a Armstrong Siddeley with an old Wilson preselect gearbox, that thing is a legitimate antitheft device.
My dad always yelled at me when I’d put tools on the battery, so I started putting part of a mud flap on them first.. so now I’m older, let just say a few times I have put tools on them, and I was reminded why not to do that. Great content as always
The battery is for fastener storage.
The core support, cowling, strut tops and the fender flanges are for tools.
Precariously balanced on top of the intake manifold is for the thing you absolutely cannot drop or it'll break or vanish into the shadow realm.
I have seen batteries blow up. Your dad was a smart man..
Stick shift never would've stopped my wife. She was as good with a manual as anyone. However, the vise grip parking brake release may have thrown her for a second.
Best regards from indiana.
is it weird that i find it impressive and hot if a woman can drive manual transmission car
@@lordjaashin not at all!
@@lordjaashin Maybe not in the USA, but in Europe you'd have to raise the bar a little higher.
@@JohnWatkinsUK My wife refused to drive a car with automatic transmission, she felt she had no control over it. She isn't particularly good with a clutch, either. Lots of revs and slow releasing.
Did it have the matching vice grip window crank.
Watching you set the air hammer there earlier in the video, I was thinking "i'll bet that thing doesn't have the little insulating cover on the battery terminal anymore" Always living on the wild side, Wes :D
Love the shorting battery shot! You keep it real!
Battery voltage low 🤣
I think Wes was just celebrating the 4th of July with a little of his own fireworks..... :) It happens to us all at one point or another.
That was some unfortunate timing, Wes. "Yeah, we're fixing the old girl up" just as Mrs Wes is climbing back aboard. 😄
Hi Wes. There is a simple "magazine" test for fan clutch in my country. Take a magazine(not wife's favorite 😄) roll it and put it into fan when engine's run. If the fan stop or going slow, congratulations, you win a new fan clutch. We also call it viscous clutch, there is something like liquid silicone inside. Sometimes could be repeared with new silicone, but only sometimes, and is temporary. Sorry for mistakes, i didn't practice writing for years.
and if you get confetti, clutch is alright ;)
Wes, you have to put more outtakes in your videos. The battery sparking was hilarious and so was the sigh of a long day in the shop. But the wife proof comment was also hilarious.
Outtakes can be good (this one was).
But the novelty of someone fluffing or forgetting a line, then swearing wears thin mighty fast, which is what a lot of out takes are.
Had to laugh when you said ‘fix old girl up’. Thought you were in dangerous territory.
Nice work.
Good job Wes. Bad new parts are a serious problem for mechanics. Some manufacturers substitute higher production for quality control.
SOME?????
Has been horrible since covid. Even OEM parts have had a terrible dip in quality control
Nice work with the repairs Wes! 🙂👍 It's sad to hear how many places just can't get parts in. Hope you're doing well 🔧🔩
We're doing great. Luckily people seem to be pretty understanding.
I replaced the whole pulley / fan clutch system on my 5.9L pre-emptively at 225k miles. The replacement clutch quit working in a week. The original clutch is still going strong at 20 years old and 320k miles. Luckily the old 5.9s didnt need fan clutchs, it never got hot unless towing heavy, just no airplane noise.
My favorite part is Mrs. Wes's face when he is videoing her on the mower... That expression is priceless!!!
I’ve done 5 water pumps in the last 2 months. I used Carquest new water pumps on all 5. I’ve had 2 come back leaking. I’ll no longer use aftermarket water pumps if I don’t have to. Luckily enough, neither of them were driven from the timing belt.
That seat cover on your mower is "pretty" special as well. But seriously, you have a very nice family. Thanks for the vids.
Yup, I was waiting for a mention on the Hufflepuff seat cover.
nice job chasing down the problem.the last time i had a "new" part fail it was a fuel pump.why is it that fuel pumps never fail until AFTER you just filled the tank.hope you enjoyed your time off.good to see your back.
In a pinch I had to buy a store brand fuel pump for my Blazer to get it going in like 2014, it lasted maybe a year. Next pump was a Delphi unit from Amazon, it's still in the truck running today.
Always at least 3/4 full. Every. Time.
Like the airhammer fan clutch tool, been meaning to buy one, wife looked super enthuased about mowing the grass, lol! Take care
Your little meeting with sparky came to mind prior to showing the blooper.
I had a pick up with a 5 speed manual when I met my wife. “I can’t drive a stick shift , you can teach me later “ she told me.. 25 years later I’m still waiting for the first lesson! Lol
Happy independence Day dude from me a Brit in the UK
Hey Wes, I worked at "a place" in Morrison that made the electronics for those fan clutches... Our customer was so hard up that they sent us pallets of defective parts so we could destructively disassemble and salvage one sensor to make more... So yeah, the supply chain is rough!
I love this channel and Ford Tech Makuloco’s channel-i’ve learned so much from you guys!
I used to see this issue all the time with the Ford 6.0 and 6.4 oil burners. The OEM fan clutch would go at like 200k miles (or roughly after the 3rd set of injectors and 2nd turbo had been replaced). Someone would replace the fan clutch with aftermarket junk and it would either be bad right out of the box or fail within weeks. The only lasting repair on those was an OEM fan clutch. I think the OEM part was made by Visteon and we were able to buy from them (through Worldpac or something) vs Ford for a decent savings.
Parts availability with Chrysler sucks because they’ve changed ownership like 47 times in the past 20 years and every time that happens, the new ownership changes parts suppliers and vehicle platforms. Once they do that, they don’t want to acknowledge that the old vehicles and old parts manufacturing contracts exist anymore, so no more parts availability. They’ve had that same issue for a long time now and it’s unlikely to get any better.
Funny that it has new AC parts and a failed fan clutch. I saw that a lot too. People would unload the parts cannon on the AC system without checking to see why those components failed. The truck would have a bad fan clutch, running the AC pressure up to 500 psi and blowing up the compressor and/or destroying the clutch. Parts cannon specialist would replace the AC system and ship it without ever checking to see if the AC system was overheating.
Awesome work Wes.
Six speed manual transmission, Wife proof. Priceless
Your sense of humor just seems so natural. Keep smiling and you'll make it through. Thanks for your "slice of life" !
It was nice having the mower noise in the background. It felt like I was watching an Eric O video. ;-)
Thanks for taking us along through your process Wes. It's greatly appreciated.
"Yeah, we're getting the old girl fixed up".....and you're getting new parts for the mower as well? Always love the content! Safety squints for the grass in the eyes.....
Nice fix Wes. Exactly right, new doesn't mean good. I just had my transmission rebuilt 3x due to bad parts that were new. 6 hours just to get the tranny out and over 4 just to put it back in. All done 3x.
Another day of wrenchin Been doing it 45 years good job .See lotta them young uns jump In with no schematic Chasing their tail Good 4 th to ya
That thing is mint for a 2007, loving owner,especially for a work truck.
Love the blooper reel. Always excellent content, no pretense - just a normal guy doing his job with a good dose of humor. Proud to wear the t-shirt.
The wife looked thrilled when she was waiting for you to finish talking so she could get back to mowing. haha🤣
Wes thanks for sharing 👍🏻. Always good to see what fun you're getting into . It's is hard getting parts that are oem. Cummis in are area is the worst at the moment. Have a great 4th of July weekend with the family ✌️ 🇺🇲
Never lay Tools across the Battery! Wes.Thanks for another Great Vidio!
I really appreciate your approach. You try not to assume things, though I guess we all do that sometimes. But you are very thorough and try to verify the problem. You also don't load up the parts cannon to fix the problem. That's the sign of a good mechanic. My stepson bought an Ebay starter ,chinesium type. It is a 3 hour job to replace. The starter worked once. That was a very expensive cheap starter.
Wow Wes I hope you and your daily enjoyed your holiday,
I have to say you know how to treat Mrs Wes her own lawn mower priceless.
If you want to spoil the misses, get a cheap table umbrella and bolt it to the plate the hitch attaches to, I did this on my mower and it definitely made mowing in the hot summer sun suck way less.
How long do think that would last before she snagged it on a tree and bent it like a banana? Might be a fun game to play...
Mrs Wes is a good girl, best you keep her. Good job fixing the truck. Many years ago I owned a cab over International with a 8v92GM, it had 4 x 6volt batteries and I did the same thing, it went off with a bang. Hahaha, scared the you know what out of me.
Nice work as usual. I’ve replaced a few of these on tractors. I’ve always heard them referred to as vistronic.
Watching that fan slowly disappear into the the front of the truck! Satisfying!!!
195k and rising! 200k here we come! Keep up with the excellent content and snarkiness!
The last clip of the video seems like a normal day for me, sparks and some adult language. Great Video as always. Part Availability and Quality today are not great, even more frustrating is the cost. Appreciate your videos and sharing your time. Thanks
The battery thing... been there, done that.
More than once.😆
In my experience anything Chrysler simply loses it's mind throwing codes if the battery voltage drops below 11.9
New doesn't mean good?! Thought this was South Main Auto for a sec
Wife seems thrilled about mowing.
Welcome back! You needed the break I think. You look a lot less stressed and back to your old self. Always great content. Thank You.
Even years ago I fixed a lot of a/c problems with a new fan clutch that did not show up until a/c was used. Now you get the ones like this but also cars with 2 electric cooling fans that one doesn't work but no overheat, but shows up in poor a/c and higher pressures on both low and high sides. Also had one with a near perfectly shaped pyramid of grass, insulation, and twigs with a rat condo on top between the condenser and radiator. Showed up at the start of a/c season, yet this thing blocked 1/3 of the cooling area, extending almost to the top of the radiator from both sides of the bottom.
Working for the parts division of a big vehicle manufacturer, there was a commonly held suspicion that we often got lumbered with reject parts from original suppliers to the vehicle factory that didn't quite pass their quality tests..... There is a difference between aftermarket parts that are pure fakes, parts that are the same as OE, parts that copy OE but are made cheaply/simply to be competitive and parts that have actually been improved from the original design by aftermarket suppliers to cure known problems.
Hope you all had a great vacation! You're the best mechanic this side of the Mississippi. Sending love from the Hawkeye state.
Thanks Wes, worth the wait, and glad you took some time off with the family. I watch all of the Ford make you loko vids, because I have fords and he’s walked me through a few shade tree fixes. Hope you have a great 4th weekend, stay safe, and best regards.
My favorite channel hands down hope u had a good vacation Wes
Sometimes ya just gotta beat the crap outta the Struggle Bus Gremlins and out think them.
That's a Wes video in one.
Definitely a nice vid to finish off my Sunday evening CZcams viewing.
Thanks Wes and a happy 4th of July to you and your family.
It's my Bebita Wife Maria's and I 19th wedding anniversary on the 4th.
Fireworks with our anniversary not related to me forgetting it and ending with a know on my head because I forgot.
Gee, ya might think I arranged it that way.
yeah! we're back to normal! great video, pleased you had a nice break, look forward to next one.
Got an 09 4500 that I've had to replace fans over and over. I wound up doing a manual fan clutch. It fixed the cooling problems on motor & trans but not enough air pull to keep condenser cool for a/c while idle.
Wes, something about your optempo that just completely relaxes me. Keep up the great work! Thanks again!
Wifey’s enthusiasm for her Cub Cadet was palpable. Hahahaha. Good stuff Wes.
Excellent video! Show’s exactly what people have been saying for years: “Dealer Quality” doesn’t mean it’s going to be any better than OEM.
No wind or rain, Max looks hot but content hanging out in the shade.
The enthusiastic look on the boss lady's face when you said we'll have a new mower soon. 😄😄
The difference between them & you Wes, you have the correct diagnostics to check the operation of new parts.
You don’t just fire the canon & call it fixed.
Thumbs up for FordTechMechloco, always learning and for our sporadic parts availability networks.
Great job Wes, after 10 years, manufacturers don't have to support their products, though I hear after 3 years or so, some claim its old technology 😉.
Plenty youngsters can drive a manual here in the UK 🇬🇧, historically fuel has always been expensive, so smaller engine capacity, small engines were not compatible with the old slush 3 speed autoboxes.
Newer design of transmissions allow much smaller engines.
Team WES landscaping doing a great job, good maintenance contract.
so im not the only one that checks the battery amperage with a ratchet? another great video! I've been having issue with my own 3500 cummins 6.7 fan clutch so this video was fortuitous ! Happy fourth !
Got two brand new defective ignition coils for a zero turn a couple of years ago, only new defective new parts in years. However, you see it on CZcams and forums about new defective parts so it happens more than it should.
You are a life saver! I’m chasing after the same issue.. brand new ac system with ac cycle switch and brand new cooling system. Yet, fan is not in the 0000 range for rpm speed. I’m interested in doing a mechanical swap
I still hate all this computer crap on all the vehicles. I prefer old vehicles ie pre computer stuff. Great diagnosis and repair. You are the vehicle repair wizard for sure.
Freaking hate those fans, we have em on a few of our forklifts with volvo engines, the ones we have with fans driven by hydraulic motors however are excellent, they sometimes last over 10k hrs of operation plus they can be reversed to decrease the buildup of crap in the rad. Nice vid as always Wes, hang in there.
Battery sparky sparky!! Happy fourth of July Wes!
Always a pleasure to watch you work
Wes is THE MAN!
They only tend to set the code for fan speed when you physically stop the fan when its in demand. It's how I riskily found out mine was faulty. Switched on A/C, felt the condenser get super hot. Then used the bottom of a hammer to slow the fan down. No resistance at all. Also when engine was switched off the fan took a good 5 seconds to slow to stop.
Came to this video from M539 Restorations where Sreten also had broken dealer and OE parts with the added nuisance of them coming from BMW with basically no warranty lol!
I had just the opposite problem with my Volvo 140 excavator. The fan ran all the time. I had to change the clutch.
The temp would not run hot enough and the emissions when crazy asking for numerous Re Gen’s all day.
Really enjoyed your video I miss seeing you on CZcams
We did a thermo fan clutch on my buddys Dodge Dakota it was the opposite it was stuck on all the time. It was super annoying sounded like a harrier jet just trying to take off from a stop sign in town. I have a 2000 Ram 1500 with a 5 speed. I was towing another truck behind me up the mountains east of Phoenix. Just chugging along at 30mph with the A/C on and my thermo clutch kept it cool as a cucumber
Glad to see Pup isnt' limping anymore. The sparking ending was the best.
Great info, experience is the key, awesome repair.
Glad to have you back Wes 😎
Hey Wes, loved the blooper at the end with the extension shorting out across the battery terminals. Too funny
Aftermarket doesn't mean bad. Sometimes it surpassed OEM in quality
Yeah, but with how cheap a lot of car manufacturers are getting today... that's not all that surprising🤷♂️
Doorman enters chat..
And some times it isn't, the fun bit is figuring out when you do need to go genuine. With my disco it's stupid stuff like the over priced engine mounts where the aftermarket ones are crap.
Just did one on my 07 Express lasted like a month at least I was warmed up when I switched to a hopefully HD one definitely feeling the struggle 👍happy 4th
Never had a vicious coupling go wrong on one of mine, mechanical mates warn about it but not so far. Plenty of grief from electrical fans though !
Being from the UK my wife learnt on a manual gearbox, preferred them, learnt from rally driving mates, got better than most guys.
Least if a viscous mech goes wrong a couple of self tappers can get you home.
To you and your family have a safe and Happy 4th of July.
Well, anytime that you work on a Dodge diesel, I’m happy. Please tell Mrs. Wes that I like her shades and I’m glad that she broke free of that cult. Happy 4th. Mark
Nice job! I have the old school fan clutch on my 2004 Silverado. It finally gave up last year. It got a little warm sitting in traffic with the AC on. I did splurge on the genuine GM. First one lasted 17 years, hope to get a few more out of the rest of the truck.
That would've been my excuse to swap to electric fans. Really easy to do on the gmt800's, you can buy a harness and use oem fans from an '05+ Tahoe. I did it on my '01 Suburban, have an '03 now and I'm getting really sick of that mechanical fan, lol.
Very good video. I was wondering about the fan being left or right hand thread. You also explained troubleshooting.
Thank you for this, you are a pleasure to watch. To few like you anymore, sadly.
sweet looking gold wing in the background. You should make a video about that.
Hope you enjoyed your week off Wes, you definitely deserve it. Mick, Northern Ireland 👍🍻
Good to know your'e back from a week off so your fresh to start working on Mid - West rust buckets.
The blooper at the end had me laughing out loud. 🤣
Great diagnostics Wes
I just went through the same thing with bad new parts. Replaced a compressor and then it would not take freon when I tried to charge it. Clutch was engaged but it would not pump. Replaced the txv and condenser and blew the lines. No restrictions. Finally ordered a second compressor and it worked like it should have the first time.
