Does anyone have a "how to" on this with pictures? I've heard it's easy, just don't want to much it up.

How To Fix An Oil Leak: Replacing Oil Cooler Lines In A 1999 GMC Jimmy

Sorry about the triple post but does anyone know what the lines from the filter to the engine are called?

Any helpful hints(or pictures) on replacing the oil hoses? That'll be the first order of business on my "Spring Break"

 

i cut the stock ones off, very carefullly, and then used hi pressure rubber tranny line
( about 4 ft) and some adjustable clamps.

been happy with that fix, 16.00

 

Autozone had a dorman replacement in stock for less than $30. Remove the splashpan and the upper radiator shroud. Very easy repair.

Sorry, this is the oil filter - radiator oil lines.

Yeah... Took me 20mins to do it. Couple things that make it really easy is a nice long ratchet extension and a swivel socket joint. Leave the truck on all fours, and jack up the motor until you have clearance to get the old lines out. IIRC, its a 12mm bolt at the engine side. It may be imperial, but I'm pretty sure I used a 12mm and it worked great. One other thing, the clips on the rad part are a PITA to get out LOL so be patient... Otherwise, very easy job, just dirty...

EDIT : I did both lines. I dunno if the OP is doing both, but if you're just doing the cooler lines to the rad, you don't have to jack up the motor, or need an extension.

 

Ok thanks guys! One thing i noticed tho is that my oil cooler hose does not have the clips that hold it to the radiator ( it's a 95).

 

Sorry Im not familiar with a 95. Thought it was a 99. If the connections are threaded at the radiator, be sure to use tubing wrenches or youre going to hate yourself in the morning. If it turns out you have the clips....I have a small pick set that worked bery well. Good luck!

 

Yep, the '95 should have the threaded connections instead of the quick-connect connections. Definitely use flare nut wrenches after spraying the fittings liberally and often with penetrating oil (especially the lower fitting). The nut tends to seize to the line and twist the line when you try to remove it (yep, ask me how I know).

 

'95 has threaded connections, much like the tranny cooler side, only larger. my '97 has the quick-connect with the wire clips.

 

Thank you so much guys!! if i have any other questions i'll let you know
