600,000 Mile GMC Sierra Leaked Oil EVERYWHERE *Replacing And Deleting Oil Cooler Lines*

[@Mikes84Corvette]

Just want to say THANKS for posting so much content. I hurt my back about a month ago and haven't been able to work on my car at all. Waiting for surgery on the 10th - and watching your videos and looking forward to your daily uploads has helped pass the time and made me forget about the pain for a bit. Anyway - thanks again! Looking forward to more videos!

[@gatlinweidler2218]

I have a 1995 GMC Sierra K1500 with the 5.7L too. I had to replace the O-rings and the gasket on the oil filter adapter last month. The biggest issue I had was finding the right O-rings for the cooler lines. I eventually had to settle on some A/C O-rings simply because they were the closest match to the old O-rings. I don't know how well they'll last me in the long run, but for now I can run it without worrying about dripping oil from the adapter. As you said in the description, quick-disconnects do suck and take a long-ass time to take out and by the time you take them out, you realize you broke them. 😠 I wouldn't do the oil cooler delete bc I made it work, but I didn't do the exact same repair you did. Was fun as hell watching you do something that I'm (for the most part) familiar with anyways, keep up the good videos.

The duramax he bought new, but the gas 3/4 tons he buys at about 300,000 miles for $2000-$3000. I thought that is a lot of money to pay for high mileage ones like that, but he is not afraid of them.

I had to change the gasket on my oil filter housing before on my 1996 GMC Truck. If I remember rightly it wasn't that bad of a job. These old trucks are worth saving instead of scrapping if possible.

[@SoCalSlaughter]

I broke my oil cooler on my 90 Suburban. Looped it til I got home but noticed my oil ran hotter, which lowered my oil PSI when hot. Oil cooler recommended.

[@69Dartman]

The 06 chevy van we have at work completely blew the crap plastic snap on oil cooler lines last year. It left a line of oil and a huge puddle under it from puking everywhere. I noticed a rattle as he pulled into the parking lot and told him that it probably was low on oil and I was going to check it out while he went in to get some lunch. I found a huge puddle and a line of oil leading from the truck. If he'd driven it any farther it probably would have locked up. Chevy truly does some stupid stuff with the lines and fittings that just do crap like we've both seen.

[@BradColemanisHere]

Thanks for the note about newer trucks. I have a 2010s GM truck and the oil cooler lines are leaking right now. I've been nervous to take it on myself due to the problems you faced of not being able to see what you're doing and also me being without some special tool. Makes me nervous.

[@43CPU1]

replaced some oil cooler lines on my old 98 suburban for the same failure. also replaced the disconnect fittings on the block so it would have fresh seals there as well. never leaked after that and no running low on oil either.

[@05milmachine90]

I had trouble with every QD fitting on my 95 Suburban. I deleted every one I had to touch using fittings and hose clamps. So far our 99 Suburban hasn't had any of those issues

[@randalhill6283]

And I thought my 07 Corolla with 257,000 miles on it was a Survivor. Very nice

[@CR7659]

What I ran into with oil lines and later trans lines on a 2002 Express 3500, here in the salt belt, is the ends swell up when they rot and do not come out. You end up cutting them off and change the fitting also. Which I did with salvage yard stuff. On that van it had quick disconnects on both ends, a little clip like the one on your window crank handle holds them in place. For whatever reason I don't think vans use the style on this truck, I also changed some on a 1991 and they were spin on on both ends, in multiple sections, I had a hard time finding lines for that one. But my 95 van, my first van, had a lot of one year only stuff so who knows. That one was a 1-ton van that for some reason had pickup type manifolds and converter (they dump about a 45' angle) instead of what the books said it should have (dump straight down between middle and end ports). I gotta think that changing your fittings to the next style would be as simple as a trip to the junkyard and picking whichever end fittings you're comfortable with and using them on your filter housing. Or changing out the entire oil filter adapter.

[@jamesm568]

I just bought OEM ACDelco oil cooling lines that came with everything I needed for a 97 GMC Sierra which were an exact fit as I didn't have to click anything on but bolt on.

[@effenfish661]

my 95 S10 with 4.3 leaks from the oil cooler lines. it looks like that oil filter adapter is compatible with my engine. thanks JR!

[@_RiseAgainst]

I'm disappointed JR didn't make his own lines. Edit: he covered this! No need to brake those factory seals. But the new ones have a fool proof bolt that holds the lines on. Edit: he covered that too. I guess I let him do his job.

[@WatchJRGo]

Do not break that quick disconnect seal... it won't work again 💯

[@gregorykusiak5424]

You talked about upsizing the oil filter - are there rules of thumb to follow? Bigger is better from a more filter media perspective, and I have absolutely no issue with adding oil system capacity in that way, but is there such a thing as too big a filter if the space is there for it?

[@adriandenson2014]

Am I the only one anxiously waiting for an update on the Aztek ?

[@iowahooch]

I fought mine changing them too but ultimately prevailed. I will say this ,as a longtime chevy truck guy that engines lasted longer after the coolers were added My 95 suburban has 270k untouched.

[@WatchJRGo]

If this was a 96 I think we would've had it the first try, the 95 is the worst quick disconnect design 😬

[@CSXtrackworker]

Its not so much the cooler as it is more frequent oil changes. My silverado is closing in on 300,000 and doesn't have an oil cooler in it. The cooler is more for heavy towing than it is normal driving.

[@SteveBassen]

@@CSXtrackworker yeah I wonder if they were trying to uprate their towing capacity towards the end of the GMT400 run and added it at that point

[@CSXtrackworker]

@@SteveBassen who knows with GM. It's weird what trucks have these and which ones don't. I've seen trucks with towing packages that didn't have the oil cooler and lines and trucks without the towing package that did have them. Normal driving in the summer my oil temp averages about 208 and going up the long mountain highway roads it'll jump to about 220 then cool down when back on flat road.

[@D4x4Bronc]

Ford's OBS oil cooler consisted of only 1 seal and coolant hoses. Never failed ever. All the trucks they failed to put a big transmission cooler on promptly failed though. Not sure if GM did the same. But to get the coolers on the Fords you had to have the towing or cooling upgrade package

APDTY just did a video like yesterday on this exact job for a '94 suburban, and all he had to do was press in the plastic clips to remove them, not use a quick disconnect. Got new adapter fittings too

[@alexsbikesandmotors]

You can just bypass the oil cooler by unbolting the oil filter adapter and screwing the filter directly on the engine. You gotta move the fitting out of the adapter to the engine. But you can fix this for free. Ive done it twice on 4.3's and it works great. You dont need the oil cooler.
