CAT C15 Injector Wiring Harness, Turns Out It's a BIG Job! 

Where would we be without our mum's, they give birth to us, fed us, nurture us and help us work on our trucks 😂👋👋👋

Your not only good driver, you are also a good mechanic. Love your videos. 👍 👍 👍 👍

It's cool seeing the motor run without the valve covers,your brave to work on your own truck!

Very impressive. I get nervous opening up my motorcycle to change the shims. If I screw up, I don't get to go play in the woods. You're working on your livelihood.

Nice to see a young guy doing his own work like an old guy did back in the day. Sometimes you just have to suck it up and do it. Great job bro.

You have a lot of courage - and trust in yourself and your ability to learn and resolve issues. Very impressive- and so calm under pressure. Nice to see you being rewarded. A great channel- inspiring video.

You're a BRAVE man, Matt! No way would I have attempted that on my own! And outside, too.

I miss the old trucks. But trying to keep an old one on the road just got tiring to me. Every trip out was something new to fix. With the newer truck I can go a couple months sometimes with just tightening up a bolt here and there. However being down a week due to an emission sensor really sucks.

The oil can walk through the wire due to capillar effect. In bad case it can walk till the EPU. In germany you can order plugs between the connector and the sensor. It stops the oil from coming into the wires. Sry for my bad english.

Got the skills to pay the bills!

The packout setup is sick driver. Brilliant idea

Your courage is something man... U dont know what those plugs or pipes do and yet u r working on it... Damn..🔥

Im loving the issues videos, really shows the ugly of trucking, makes everything more enjoyable when you fix, upgrade and try different things

OLD TRUCK I have been driving 1985 359 for 28 years KEEP ON TRUCKING BROTHER ✌

This is what I was waiting for! Startling!

13:33 I need so badly such huge "momentum arm", for my seized, dumb, stupid, bloody, stucked oil pan nut 🤣. Just exactly right now!! Good job Matt!! Keep it up bro 💪😎

Great video and great job! Your parents’ place is nice. The bird life there sounds awesome and was a nice soundtrack to your video.

Nothing like a guy who knows how to fix his own truck, I’m sure you saved thousands on this job by doing it yourself. Today lots of guys don’t even know what fuel injectors are let alone work on their own trucks 😂😂 Props to you bro, you got guts.

absolutely love this style of vid

a very good job man!! I really like your videos!! 👍🏻💯

Enjoyed the sense of humor Matt , you need one when working on the moneypit , albeit a lovely looking moneypit .😁 nice looking tool kit by the way . It looked a bit daunting but you did a great job , the shake ometer 5000 looks a handy piece of kit to have 😁 . I must say she sounds great running as always .

Got to admire your braveness (especially you not being a trained mechanic) but as someone else commented .. always cover induction tubes ... and a smear of silicon on multiplug 'seal to casting' would prevent leakage .... You could do with a heavy vehicle mechanic as a friend ! ! ! .... respect to you from England.

Excellent job dude I really love your videos they are very interesting at least you can work on your own truck very nice be safe out there here from Ontario Canada 🇨🇦🇨🇦🇨🇦🇨🇦❤️❤️❤️😎🚛

Seems like she has some prettt good power!!

Great video buddy

Great video!!

Good job dude! Ya know its bad luck not to have a name for your truck. I named my 97 F 150 " Old Mr. Ford"! I just recently named my 2018 Cadillac CTS "Mrs. Finally Paid For"! Be cool--be safe!

Your a funny fella. Hello, Burglar! Knock Knock, must be having a shower. HI Mummy, that's funny and good value. Your a good fella, a Good son.

You got cannon balls to take that project on my man! I earn money to pay people with a higher mechanical IQ than mine to do jobs like that.

Thank you! Just got to the sticking point on mine. Came to RU-vid to see if I really needed to remove a Jake rail to get the damn thing out. Skipped straight to the exact point I needed in your video. Thank you for limiting my swearing today. Guess I'll remove that rail now. 😂😂

I learned that same wire separator trick from david on roadkill!

Only way to keep money in your pocket is to fix it yourself. I have a 17 389 I love tinkering on . Keep up the good videos

I still love working on my truck it’s the only way to go and it gets done properly nearly every time I use a mechanic I regret it. Outside awesome listen to the birds cheeping nice a quiet.saving a small fortune tax free. And really getting up close and personal with your truck. You just can’t put a price on how good that is.well done ✅👍😊👌

Dude, is that Spicoli's Dad's tool set? 🔧 Most excellent Matt 🤙

Sir, I asked you a question, during a previous vid of yours, had from a Riding Shotgun video, and realize you probly have no idea what I'm asking about. Sorry. Semi seriously; do ya learn how to be a mech of these semis at Truck Driving school too? 😂 Hahaha your brave openin that engine up. How coragious. I love hearing the happy birds in the yard too. Awe, shoot rain. Love ya laugh. Peace 😊

my heart sank when the rain started...

That’s a huge job

I don't mean to be critical, but I was so afraid of you hitting one of your bolt/nut holders and knocking them off and nuts and bolts going everywhere. You might put them on the table to be safe when you aren't putting them on or taking them off. Also, please put a cover over the air intake for the turbo. Imagine this; Oh darn, I'm missing a nut, where the heck is it? Can't find it anywhere. Get another one and move on. Start truck and hear rattling in turbo. Uh oh!! I learned these over the years the hard way, hopefully you don't. Nice job, your patience is great, maybe you threw wrenches off camera? :-) My jobs aren't usually complete without racy language and wrench throwing. LOL!! Did you ever think of using a drone with camera system to assist in backing trains? I know you can get them that will lock to your location and follow you.

You did a great job bro. I deleted a previous post thinking you were still a accert motor..my bad the single turbo in my face….my bad. But this is another theory. Its a long shot but the Iva’s are disabled from your tune..There clearaces from the intake rocker are 20 thousand give or take.We know they are disabled…They are hydraulic acctuated pistons like the jakes.They have springs on the actuator pistons to make them retract once the ecm commands. Its a far fetch but maybe one of those dead iva pistons is bumping a intake rocker arm giving you fits

Hope this is not too late. But I had the same issue on a 2003 with the low airleaf suspension. Turns out I accidentally replaced a suspension airspring with one from a non low airleaf suspension and therefore my rear-end height was always out "height specs" . Replaced both rear airsprings with factory bags and problem solve. Good luck

Nice bro ✌️

with the cold start issue it might possibly be injector cups. I would assume they are original to the truck. just food for thought keep up the good work and keeper greasy side down Matt!

Yikes. That’s an “inside” job, as close to a clean environment as possible but you GOT TO DO..what you GOT to do!

Bonjour Superbe présentation sur réparation de injection Je suis un chauffeur routier français je me suis abonné 👍👍👍🤣🤣🤣

I have an 06 acert and had the cold start issue and it was the coolant diverter valve.. either the harness or needs rebuilt/replaced.... Also the jumping I had was my throttle sensor under my peddle but yes could be rear-end. Also replace all fuel lines. Be sure your not getting air in fuel system, ive seen them get fuel from the hand pu.p primer on the secondary fuel filter housing. Hard start can also be your check valve on the secondary fuel filter housing... its just screwed on in sode... its what keeps fuel in ur filters to start. Last would be your cam and crank sensors... they dont alwyas throw codes when they are bad and cause that bucking. And update on the situation would be appreciated, good luck

That was a stressful watch 😱

Man, you guys really got a put what year it is

Read your cat manual your mom is awesome make sure you give her a big pat on the back for helping you . Very cool.😊

The gray smoke when cold is just a bad spray pattern from the injectors getting old when its cold , my 2003 MBN with 1.5 mill 45000 hours did the same , but it ran fine try change the check valves on the fuel filter housing they are 3 , ones a bleed screw and it's solid and 2 have ball valves in My c15 just died and spun a bearing at 1.5 million I ended up getting a MBN ACRERT, with a single turbo conversion 17000 hours on the engine It had the IVAs deleted on the ECM. It just been installed in my FLD 132 and I'm ironing out some bugs

Hell yeah!!!

Must be the Woodstock Ontario on route

You’ve got a lot of courage Matt. I guess it’s hard to get perfection from the old girl… or is it an old boy ? Can you tell us that ?.. at least I think it’s an old boy, cause you said it’s the name of an old cartoon superhero. And I don’t think you want to ride in Woderwoman. Hmmm or maybe you do 😜. just foolin around he he .

That shake could be coming from a trailer tire. Ours does it at certain speeds. The vibration at an idle point I’m fighting myself.

7:10 yikes I thought those 2 little bolts were gonna fall in.

You just have to remove the steel lines at the front of the head and the rocker cover comes off .it will squeeze past them if your mean with it , but risk braking a tab off the cover

3400 series engine are cam in block aka push rod engines and... C15s are cam in head engine aka rockers actuated Is that correct?

So I’ve been watching a few of your videos. Do you think you made a mistake buying this particular truck ? Considering all the problems you’ve had? I was impressed with your shifting video. You have your own authority! Does this mean you have your own customers? Or do you use a broker? And doing the mechanical repairs on your own , is that affecting your loads , or is it really saving you money. Kudos to getting into this with great aspirations

Ask KT3406E. That guy will know what that oil quill thing is

❤

Rtv young man Wac em with rtv a bit

I would have grabbed some Puppers and helped you

Shake o meter 5000. I might steal that one! Lol but i have vibrations thur the truck at idle and driving. I have a frail wire on the injector second one up front. Could that be mines too?

I have something similar going on with my 05 379 C15 Acert. I’m wondering if it’s something in the power converter?

Injectors or harness. Everytime it's happened to us its been one or the other. At this many miles it's hard to get them back to the smoothness of a new truck without buying literally a new truck in parts or literally the truck

Did your new injector harness come with the round plastic retention pieces the nuts go into that go over the 2 studs on the injector. Mine came off in 2 halves and my Cat dealer cant find anything on them

34:03 lol

Should have gotten a Sony, we dont have those problems. Now those zip ties will cut into the wire shielding instead.

see how your external wires look swollen? the connector is sealed so well that when oil starts pushing into the connector it can push right on up thru and into the wire on the other side. that changes the impedance of the wire and messes with your injectors.

I gotta check my injectors on C15 acert, getting diesel in oil, any other ideas what to check for?

Hey you ever find out the problem? I’m going through the exact same problem on mine

How much was wire harness and how long do you think it took

Check your bearings on output shaft of transmission..

Hi

Good job , When your engine is cold what you're talking about , All of them are gonna do it , Just let it warm up on its own , That's a cold start poppin missing everything you're talking about, in your kind of weather pull up a cold START page for truck diesel engines And then you will understand what I'm talking about , The shaking you're talking about , you're correct one of the injectors , But whatever you do just do not replace ONE, replace all 6 if you do not a month later another one's gonna go , you're just gonna keep getting into the engine until you replace all of them , To get the oil and fingerprints off your engine Go buy yourself a couple cans of oven cleaner , Spray all over your engine spray it on everything let it set for about 30 minutes and take a water hose to it Works pretty good , She sounds pretty good MATT

🖐️👏👍🥰

I would just get a whole new harness if you could

Those will break down overtime, zip ties, get brittle or break apart and you will have pieces in your engine

Willing to bet that the vibration issue is a bad harmonic balancer

What's up

Hey buddy did you find your miss??? I got vital info cat has a factory defect in these heads its the injector seats you can remachine them on the truck..the tool# C153055 or C15-3055 it's a two piece set after you do this unless seats are beyond repair...you won't have that miss..try to look up cat 3406e/c15 injector seat repair to learn more...the miss is a common issue stop wasting money I've done all this once seats re.achined injectors seal in seat on head the bottom o ring sits even now.cat will not tell you this or admit it of course they want us buy parts. When injector dosnt seat we get air in fuel...wish I was back in Ontario I could fix that for ya No more combustion( air in fuel) ill check back on ya

whoops ... 🤣

Dont ever sell that truck for one of these new POS

i was so nervous seeing all those bolts sitting on top of the coolant reservoir

Cool video thanks…I will say you ain’t scared of nuthin’ ….great repair job
