This video covers the process of removing, and replacing, leaky oil lines that run to the radiator on a GMC vehicle. The vehicle repaired in this video is a 1998 Chevy 1500 Silverado with a 5.7L Vortec engine. The oil line repair procedure covered in this video should be the same or similar on many other GMC cars and trucks including Blazer, S10, Trailblazer, C1500, K1500, Silverado, Tahoe, Yukon, Sierra, and and many more. How to repair oil lines that are leaking in a GMC car or truck.

i got both lines one has a sticker that says "in" the other says"out" but they look exactly the same, can i use either one for upper and lower.
Thanks for the clip info with Dorman brand. I'll pay the extra 10 bucks for a Delco.
good Vid ,Man makes me want too do my 95 K5 but what a mess these lines make!
Any idea if this will fit the 1986 Chevy P30 ? In this case the P30 chassis is fitted to a Fleetwood Pacearrow Class A Motor home body. This is a 1-ton chassis I suspect that the C or K 30s would work. Am I correct?
good video.
removing the fan shroud would help.
Whoever designed this line installation system at Chevy should be fired. How can you have a heavy oil hose such as this be just clipped into an "O" ring and expect it to last? Just plain stupid! A heavy oil line attached to a rubber "O" ring. I think the reason Chevy did this was to push their trucks through the asseymbly line faster for more profit.
I have an s10. How do you get to the back bolt that holds the back part of the oil cooler line on? It's in between the hell housing and I want to say the transfer case.
What is the name of the hose that the engine coolant line connects to that feeds the rear of truck?
How much money did you spend on parts total ?
hi guys I have a 1993 Chevy Silverado and looks like the bottom line threads on the radiator are stripped out any tips on how to fix that.
Please help me out! What part numbers are on your lines? Can't find those lines anymore around me. Thanks!
i removed the stroud and water pump fan. gave me allot of room. i didn't use doorman crap. i bought summit heavy duty oil pipes. i also bought 2 barbs for the oil filter housing, clamped both sides. same for feed and return. a year later, not a single speck of oil leak around my pipes. best investment i ever did.
NOOOOO HE USED A FRAM
Ok I have had multiple problems with these oil cooler lines.. The best advice that I can give everyone is to take them off take an Allen wrench and stick it into the threaded pipe on the oil filter adapter kit… Take the threaded pipe and insert it into the block and tighten.. screw the oil filter onto the block and throw the rest of that shit in the trash and it will never leak again…… I'm just trying to save people a lot of headache and money.. Problem solved and good night… Your wasting your time watching any of these videos..
on your lower radiator connector if you remove the upper fan shroud and the 2 10mm bolts to the lower shroud you can pull it back enough to allow you a little more wiggle room for the lower line and thanks for the info about the quick disconnect i wish i would have seen this before i did it all the hard way and of course mine was a frustrating engine swap and i reused the original line one of which is leaking now so i get to do it inside the truck now
What size are the bolts for the oil filter housing?
leaky oil leaky radiator pain in the but. I would like to figure out how to hack and plug off the completely useless oil cooler.
i own a 96 chevy 1500 5.7L and im having problems finding out which line is the return line on the radiatior top or bottom?
The only time you need the oil cooler lines if you are towing something that is extremely heavy like a camper or bobcat.. This is a fix for the small business man…They come out with that so everyone can spend a lot more money to have it repaired when most average people don't tow backhoes with a chevy astro van..
You may have said it in the video, but I must have missed it. Do you know the part number to the fittings and where I can get them? Also, do those by chance come with orings already inside?
I've got a 94 Chevy Cavalier (front wheel drive). My oil line is leaking, and the tubing lines on mine were rusted through worse than his!…lol. I have never changed these before. On mine, since it is front wheel drive, the lines are only about a foot and a half to 2 feet long. Watching a lot of these oil line and transmission line videos, what I don't understand is, why not just use hose fittings and run high temp rubber hose the entire length? Since mine is a short run, on the online auto parts places, mine only cost about $11.00. So, cost isn't the issue. Just seems it would be a lot easier installing hose fittings and not have to fool with all those tube connections. Hose fittings are a lot less hassle than tube lines and connections. I realize if you have a rear wheel drive, and longer lines to run, you may need the tubing for more support while snaking through the motor. But a short run like mine, why not just use hose and hose fittings? Has anyone just ran hose instead? (note to self: get that PV blaster spray, because I'm sure, mine have never been changed and are corroded really bad)
i never replaced the fittings hope i wont be sorry. adv auto wasnt very helpful lol
Mark,
great video, I have used crows feet on the radiator end to make that a little easier. Thanks for all the tips!
