6.7 L Cummins EGR cooler. Detailed diagnosis and replacement. Watch a pro do it correctly 

Dillon is a great wrench. I love his attention to detail. He treats his jobs like they are his own vehicle. This mindset starts from the top,you Dave! You have a 1st class shop. Congratulations Pete

Dave I am a 77 year old gearhead. Your videos and your shop are amazing keep up with your attempt to educate the masses.

glad you stepped back and let dillion do his job. He is a pro. Enjoy watching him work.

And there’s me with my 5.9 Cummins rolling up to half a million miles with no major injuries to my engine other than water pump, alternator, new batteries, new cross over cables, and a dual clutch disk

Dave it’s a testament to you how professional and proficient your techs are. It’s nice that they can explain things as well as the teacher. Your service to your techs shows up in their work.

We need more videos with Dave and Dillion! Dillion is the Mechanic we all wish we had at our local Diesel shop. Keep that one happy Dave! 🇺🇸

True Pros share their ”secrets” / knowledge. Competition can’t exploit secrets from the best in their field.

Dave giving that truck a solid colonoscopy

That’s a new truck to be having EGR Cooler failure! Good work, guys! Love the videos!

Hello Dave: Thank you for this video sir. As a former independent repair shops owner we never got involved with diesel engines.But I must commend your mechanic for his thoroughness, expertise, caring, & cleanliness. His level of concern as well as drive to VERIFY YOUR 4 C'S & push through the surrounding components + O Rings to me is uncanny. I understand that he has performed this cooler replacement many times but I did not see his just do a remove and replace operation. It should be noted Dave is that I can see your own personal know how. Expertise, experience, and take no prisoners attitude you have instilled in all of your techs thus far. Dave, the way you do & go about every repair is just normal procedure = OUTSTANDING SIR !!! Dave to find, a crew like yours is just like family as well as the way they perform in my eyes is admirable + you should be congratulated that your vision has come to fruition. Thank you sir, God Bless you, your family, and your crew. ❤❤❤, TMP from N.J

One thing I will suggest is that, Dave, when you get a ram diesel, for good customer service, check the heater grid bolt, may save a blown motor

The point of EGR, other than to prematurely destroy a diesel engine, isn’t to be “reburnt” but to provide an inert gas to help displace oxygen. This inert gas can’t react with fuel thereby reducing NOX emissions.

It's really interesting to watch someone who really knows what they are doing. Really enjoyed this episode!

I know I’ve said this before, but FENDER COVERS, FENDER COVERS, FENDER COVERS! Once upon a time in my tech days, I had a helper do an oil change on a truck after we’d finished doing some injectors and he (allegedly) stepped all over the guys chrome bumper with 36 grit sandpaper embedded in his soles and put a bunch of micro scratches in it. Of course, none of this was noticed until the customer returned to this home town dealership on the other side of the country where he had them replace the bumper for almost $1000. I couldn’t contest it because we didn’t have fender covers on the truck during the oil change.

I have worked in many shops in my career and have left them almost every time because they ripped off customers and would try to sell the customers things they did not need. For example a customer brought n his BMW M5 for the centerconsole doors not closing. My service manager tried to sell an entire new console to customer for $2,400 and t only needed a smll mechanism for under $200. I got in an argument with him and I ended up the one losing my Job over doing the right thing. I got a hold of the customer and told him what had transpired and he hired me to fix his car and than ofered me a job at his machine shop. I wish Daves shop was closer to me because he is the kind of person that I would apply for a job with always doing things the right and honest way he seems to be very transparent with every job they do.BTW that was a BMW dealership in North Carolina

this was one of the coolest episodes I’ve watched. As a mechanic in the 70s 80s 90s the tools they have now are really nice to have. Great job Dillon!

Dave is the kind of shop owner thats not afriad to get his hands dirty, just the kind of shop owner everyone needs

Wow, editing is so professional and Dillion is a wonderful teacher

I like watching these kind of videos

The day after, I bought my ram. The egr cooler and the exhaust system fell off on the road, and I never looked back. Had live wire installed

Really enjoy these videos. Very informative. If you can't learn it here, you're just a bystander.

I have been a technician for 37yr and I see one thing that you forgot. Where are your fender covers? Always protect your self and the customer. One trip to the body shop can kill your profits and relationship with your customer. Keep up the good work.

Dave’s lucky that he hired Dillion. Seems like a nice guy that also happens to be a damn good mechanic!

Proving your shop's integrity will guarantee success. Well done!

Thanks for the tutorial Dillion

Do you guys have vehicles coming from all over the country or are you dealing with people in the area? You guys gotta be one of, if not, THE top shop in the country for this kind of work, stellar job every time.

Kroil- is the Best penatrating oil hands down. It even works better if you let soak. Only stuff I will using replacing exhaust manifold

I have blanked my EGR and removed the EGR cooler, it functions better! the reason for the blank EGR oil lumps blocked my inlet and inlet valves.

As a 5'9 tech of 10 years. The most impressed I've ever been with one of these videos was lifting up the front end, removing the tires and lowering the truck to working height. Such a simple and obvious thing to do yet so beneficial

My 6,7 Cummins was deleted. I took all that garbage off of the engine. Now it identifies as a non emissions 5.9. It runs way better and the engine oil stays clean. It doesn’t turn black immediately after it is changed

I'm not a gearhead, but I love watching your videos, always something interesting to see! I also enjoy the attention to detail all your crew show, something that seems to be lost in today's world.

Dave, you run a tight, Shop. Awesome job.

u rarely talk. great job! clear and informative.

This video is a work of art,detailed to perfection

Very satisfying episode. Between Dillon's prowess as a tech; his simple explanation of the process as well as the replacement EGR Cooler itself; coupled with the music, this is one of my favorite episodes to date.

Very nice work Dylan, we have very similar styles and even use the same tools! I do recommend using fender blankets for two reasons I see in this video. One be careful of that belt buckle especially with the shirt tucked in. Also those air hoses and vac filler hoses will pick up all sorts of dirt that sticks to them from the coolant being on them and will scratch the crap outta a nice black truck like that!

I bought a 5500 dodge with the 6.7l for 1500 bucks because the owner was told it had a bad head because it was burning coolant. I towed it home statered checking it out egr cooler was blowed out. Fix it for 46 bucks just put block off plates on it.

Loved this format of video! Dillon knows his craft and explains it very well. Keep em coming!!

Nice work Dillion and Dave!

This seems the best channel that covers all things trouble shooting, very good for DIY'ers.theres a lot of things we do, that they never thought of. Your channel might open a few eyes. Thank you.

Dillion is a class act. Very thorough with instructions on this repair. Great job, Sir!

Dave, I’m Ed and been following you for about a month now. Great content and useful information overall. Today, just one concern I saw that I’m extremely critical about “Safety”. Noticed your technician was not wearing safety glasses when he was under and opening coolant drain plug. Thank you and your team !

Hi Dave Dillon, this is the perfect format for your vids, love it!

I had to do this same replacement on my 16’ Cummins (Bullet Proof makes a quality piece) but what I discovered later was that much of that vaporized coolant was going into my oil. A Blackstone Lab periodic test revealed that my oil was contaminated. I did a double oil flush and another lab sample test and everything was good.

You guys are very informative which makes watching your videos entertaining. Glad I held onto my 04 Ram diesel. Not the 4.5 where they did the addition of installing EGR and catalytic converter.

Even though I’ll probably never work on cars but very satisfying watching someone showcase their trade 👏

Love my 2013 Dirtymax. Irriates me how much these trucks cost and the EPA is killing those engines.

Just want to say that this is my favorite style of content! I watch everything but really love watching the wrenching!

You have an outstanding talented staff that know their business.

So professional. Love you guys!

💯 % Quality work and quality replacement parts. Dave & Company, you guy's Rock!!!!

Bullet Proof makes some nice diesel components, top notch stuff

I really enjoy when your guys do a job and show the process I'm a gear head myself and love learning new stuff I've never worked on a 6.7 cummins I've drove a few but never worked on one ty for the education

Dave and Dillion, a great job, very good diagnosis, correction and final check. Skill shows and excellent communication.

Would have been a great opportunity to blank that EGR off. Also why aren't you guys running crank case ventilation filters in the states? Would stop a lot of your intake manifolds clogging up so much. From Aus

Great Job Dillon 👍

Nice job brother thank you for explaining what it does also God Bless You All out there

Great content and great job to everyone that makes this channel happen. I love your channel Dave!! 👍

Did three of these bulletproof EGR cooler installs recently. All on 6.7s. They definitely make a good product and have great customer service

Enjoy all the information I get out of this channel!!! Even though the only diesels I touch at my shop are German diesels. GREAT work guys and always look forward to new videos and shorts.

Fantastic mechanic. Thanks Dave

Nicely narrated !

Great repair You are a pros pro😊

Like watching artists at work, great job guys

Man that tools for cooling system to make sure no air bubble so awesome!

Dillon is the best. A great face on your company. Cheers from Canada!

Great production. Awesome work

holy crap I never realized how much crap that was actually removed off my 6.7 . I don't have any of the egr crap . I have like 5 plugs that are tied up out of the way not plugged into anything . I was wondering what they were for lol . and I have no cel . and yes the bulb works .

Love the videos and the information. You have an awesome team for the awesome shop. Keep fixing engineering mistakes love it.

Watching the video from Kenya 🇰🇪🇰🇪 .it was pretty much good video with One of the colleagues .👍👍😁😁 Thanks Davis for your work shop

Hola 👋 señor Dave!!! That was a great video just looking at the high level of skill and knowledge that you and your workers have is really impressive and even at the end he took the time to wiped around the engine parts to show a great job 👏 very neat clean and professional…You guys are amazing 🤩…keep up the great job…it’s Friday again and this weekend You guys need to take it easy and enjoy the weekend with your love ones…Saludos!!!👋😃👋

Scotch brite is very effective as long as you’re mindful that no old material/debris gets into the engine in any way.. it becomes embedded in softer metals (aluminum etc) and can accelerate wear . Service bulletins were issued from some automotive manufacturers (can’t recall which at the moment) to their technicians Advising them to avoid or use only on parts that are not attached or come in contact with the engine internals unless they can be thoroughly cleaned and rinsed afterwards.

Awesome video, great work. Thank you. Dave

This Tech is an animal!

It's like watching artists work 👀 amazing

Simply brilliant Dillon

Thanks Dave. Great job. Good info. God bless. Happy trails.

Amazing detail to all the jobs that y'all do on here Dave great job love the videos keep em coming!

Love the music and editing done on this video great work very enjoyable

Interesting video. Stay safe my friends. God bless you all. 🙏🙏🙏🇺🇸🇺🇸

After seeing all the problems with the new diesels, glad I purchased a gas job! As usual great job!👍

I remember my dad spraying the kroil rust penetrating fluid back in the early 80s. On a rusty boat trailer. Very distinct odor. Still Very effective

Awesome video! You guys have all the cool tools.

diesel trucks always have issues. make sure you have money on the side for break downs. can't go more than the 15,000 miles without having issues on a pickup. Daves Auto center, they know their stuff. I feel like if I ever have a major issue inside the engine, I will trailer my ride to UTAH. get it done right the first time

Using Kroil? Good to know it still exists. We used this when fixing typewriters back in the early 60's. Wonderful stuff for getting into small crevices or tight spaces or rusty threads. It has

You all HAVE to be in high demand in that area of the country! The knowledge and expertise displayed is amazing

Good work! Making it look easy!

Really nice to watch and follow the steady, methodic procedure Dillon does....not less impressive too, kudos to Dave for giving the stage fully to Dillon, it shows a lot how valuable a good management and healthy boss-employee relationship result with an admiration and allegiance from their customers (in my case, watching from far away, a channel subscriber 😁)

Great attention to detail, this why l subscribe to your channel. Great show Dave.

Great job

Nice find nice fix

am i the Only person that noticed him Replacing the HNBR O-rings with Regular Black o-Rings. Great Job overall except for that. Those GREEN O-rings aren't there just to look pretty ! Some tips for him - 1) Use Silicone Grease on O-rings to Pre lube before assembly instead of assembly lube. 2) assembly lube is usually a petroleum base product NOT something that should be put on a Black O-RING. i Do Recommend You Go back & Install the HNBR O-Rings. HNBR O-rings Are Designed to withstand Wider Temperature Variations & Better Chemical Resistance than standard O-Rings.

Thanks Dave and Dillon for pointing me the direction of the EGR cooler. I have been searching for external coolant leaks. Loosing minute amount of coolant for a couple weeks, Fearing a head gasket, I'll check the EGR cooler. An obvious place to look now that you pointed it out, Duh. Appreciate the tip about Bullet Proof too. Thank you.

Awesome job thanks for the video👍

Dillon is a NATURAL! Have you considered doing carbon clean soak on the piping to the EGR? The filter top on the motor as well? My guys in Volvo shop use a cabon clean service company and always have fresh clean hoese and top of engine part to swap in when they do work on the sytems.

Love attention to detail 🫡

a real craftsman

Master Mechanic

How great it must be to own this truck and know your repair is being done by the best around. I’m a Ford guy, but that’s a nice Ram truck.

Great job, Dillon. Professionals like you are harder to create and find these days.
