I've been a top notch -car- mechanic for a decade now- and I would come work FOR you. learning how to fix big trucks is highly renjoyable

We have a 1998 3406 in a freightliner, been losing coolant sporadically for several weeks now. Also ran rough for a few minutes at startup a couple times. Just today discovered coolant in the fuel return line. Thanks for steering me in the right direction. Great video!

this guy is good, very knowledgeable. thanks.

Brilliant videos man. I really appreciate you sharing your knowledge and expertise.

Awesome video again Adept!

You need a flex head ratcheting wrench! I love it for doing Volvo/Mack injector cups.

Great videos. You are very informative. I am having problem, 3126 oil in diesel fuel. What are you thoughts? I have changed injector o rings?

Love your videos man. I'm a aspiring diesel mechanic

Hey!! adept good to see you again buddy.

great videos, I have a CAT C7 in my motor home, I had a complete HEUI pump injectors replaced 6 months ago. Took in for a Preventive Maintenance. Went to pick up check engine, display said ECU low coolant. Coolant full but fuel in coolant, no leaking of coolant though to my knowledge. thoughts?

Good info! What about when engine oil gets in the fuel tank? Could that be due to bad injector orings or seats? Engine is an isx cm870 tia!

Great video. Very interesting. One question however; after you have pulled the cup and you use die grinder to clean area where cup goes, how do you avoid contaminants going into the cylinder? Also you said to clean the cylinder. That would be hard to because you have a small opening. Only way would be a small vacuum hose ? I’m fairly new to this kind of stuff so forgive my ignorance. Thanks.

How hard is it to remove the spacer under the valve cover for more working room?

Thank you for this vidéo , i have same problem some diesel in my radiator on my volvo genset TAD734 GE.i think the problem is the injector sleeve or o-ring. What do you think?

What’s the easiest and best way to plug the injector tip hole to prevent debris from falling into piston? Working on a 3406

Tks I have head ache with my freightliner but now you help me, and I trade to fix the problem only looking for tool to remove the cup inyectors,

i dont know how people can dislike ANY of his Videos!😠

Keep making videos so i learn a lot from them i love caterpillar engines 👏👏👏👏👏👌👌👌👌👌👌👌

Prefect & satisfied video,Cat ,,,keep it up

I have coolant in the primary fuel filter but no fuel at all in the coolant recovery tank. Could anything else possibly be putting coolant in the fuel filter? 1998 C-12. Coincidentally I turned on the faucets for the heater core and one day later I had coolant in the filter.

Do you have to reprogram the injectors I recently replaced the cups thanks to youre video but now it is missing not sure if you have to program them or something

I just had mine done and it seems there is a little residue or there is more fuel in my tank. Is it possible to have a small amount of fuel residue? They just drained it and refilled. Didn’t flush system

I have a cat 3406b engine that's leaking water around the spraying nuzzle have any idea of what can that be ? THANKS

I've got a C-15 6NZ fuel coming out of the blowby tube is this injector cups ?

Just strated to repair CAT D5N with same issue, at the start I thought crack in head, then remebered bad cold start on CAT 962gII - and bingo we got bad sleeves and O-rings.

very good job and I learn from all your videos. thank you soo much... REGARDS

Excellent video. Thank you. I'm not a mechanic but I do need this info when talking with my very skilled diesel mechanic.

Thanks for the video my 95 7.3 has coolant in the fuel and it only has it on start up when cold so I'm thinking I will have to replace all the cups

Hi I have a 1994 3116 and it dumped my entire tank of fuel out of the coolant overflow I can’t find a tool to pull the injector sleeves for the mechanical injectors can you tell me what tool I need? Thank you

Great work thanks for sharing

I have a C7 with a 94-1 code. Low fuel pressure. Shows about 4 psi at idle, I've hooked a guage to it and can confirm the low pressure so it's not a sensor problem. Bypassed the truck completely with a jumper line and same thing. Changed the filters and lift pump. No fuel leaking from injectors from what i can tell. I'm surprised the engine even runs on 4 psi. Any idea what may be causing this?

Awesome video👍🏼

How do you ensure all the debris is out aside from compressed air?

i don't understand how coolent couldn't get into the oil also if the orings were bad?coolent coukd push out up top then into the oiling system?

So is it possible to get fuel into the coolant through bad injector cups on a mechanicaly injected dt466... the injectors have no o rings just the copper washers I have no compression gasses coming out from the injector body on the outside of the block.. just wondering if it could still be injector cups or would you lean more toward a cracked head or something

I am getting fuel in coolant. White smoking a lot and smells like raw fuel. Loosing about 3 gal of coolant a week. I pulled all injectors. #2 looks discolored from heat. The bottom injector cup o-ring is mostly missing from #1&2, I haven't pulled the rest of the cups yet? Can missing o-rings cause my problems? I'm thinking I may replace #2 injector and all injector o-rings. Thank you

This just happened to my 2002 GMC 6500 with CAT 3126. Truck had a hard time starting, once it did, I noticed the overflow bottle filling up. Waiting for mechanic, hopefully just the injector seals blew.

Great info. I wish I had a C7 in my F250! :))

Im doing this job on a c-15 acert right now. Does anyone know the part numbers to the tools that pulls and installs the cups?

Was just quoted 3500 plus tax to do injector cups on my c7 is there something I'm missing I expected cat to be a little more expensive but that sounds crazy high

Is there a test to determine this?

Great, in my case it was coolant in the diesel system, but the same problem. 3126 Engine

I wonted to see the o ring do the o ring go in before the cup or after ? Video is grate

just a question after doing a job like this is alright to start it up or is their something special you have to make sure you do before start up?

So I'm getting some coolent in the cylinder but no compresson inton coolant system could a failed cup be the issue? 3406e 5ek

Great video!

Hard head if you got regen engine then he stop there !! Why ?? Can u pls explain ? It was the best part tho.

Is the c12 the same? Great vid .Keep them coming.

I'm getting coolant in my diesel. Will injector cups fix this?

First off great videos. You've helped me a ton. I had this exact issue on my western star 3406. I did every per your video. Mine differed a little in the sense that it has two nuts to be remove from the jake housing and there's two connects that run on top the top of the jake housing and clip in and says torque to 10lbs and had a snap ring. But my issue is after replacing the cups and flush/new coolant, my driver went to start the truck this morning and it attempted to start just once. I just got here and it made no attempt to turn over, the only thing it did was a loud audible Thud or slam.

My fuel return line is so hot. My engine is giving a hot temp sensor read. Can the heat be related to the injection cups needing replacement? I'm in a blind here. Dont just wanna do r&r service. Can anyone help

Thanks for the video. I have to do this to a Detroit 60 series 14 L engine is it pretty much the same process or do I have to remove the cylinder head for that specific engine

I just had my 2015 Detroit DD15 with just over 900k miles repaired. They pressure tested my injector cups and said they were fine. Turns out the cylinder head has a crack. No remanufactured cylinder head in the foreseeable future so they installed a brand new head. That repair cost me 15k.

Hi facing same issue in skoda Fabia, what can be the solution

Hi I just replaced the cups on my injectors. Now when I start the engine has no power and black smoke out the exhaust. My original problem was that it mixed diesel into the cooling system. Any thoughts on what could be happening??? Thanks Al

How do you know the diference when diesel in coolant or oil in coolant ? Mine looks like has some of that but very few little like black points

Good afternoon, I’m a local mechanic down in Houston TX. I have a 2005 Twin Turbo C15 CAT. I want to know if it’s possible to replace the injector cups without having to remove the heads ? Any information would help. Thanks

Always so calm and cool you are! I like my Mechanic to be mellow. I dont want my mechanic sweaty and looking side to side shifty eyed and fidgety when i come to pick up my W9...lmao. Good stuff Adept as always 😎

Great video

I have a 1995. 3116 in a topkick. It's got a miss also and hard cold start with a bad miss and really heavy fuel smell and white smoke on start up. Runs better cold but develops the miss as it gets warmer under load. Is the cups a culprit?

Thank you for your video

Awesome

On the 3406 these will cause coolant in the oil, as these Don have a common rail fuel system

I have 97 freightliner century with a 3406E. I just replaced my injector cups and injector rings. Flushed the cooling system, filled with 50/50, crank the engine, turned on my lights and it was running great. Then the engine just stop. Turned off the ignition, turn ignition back on and noticed that the gauges did not cycle. Turn the key to start and the engine fired up just fine, but none of my electrical gauges are working. No wipers, no ac, engine fan running constantly, windows won’t roll down. When I turn on the headlights it kills the engine. Also noticed when I try to roll down the windows it cuts the engine. Please help! Any idea what’s going on?
