leaking oil cooler line

[chevyaz]

I have a leak in my oil cooler line at the crimp and was wondering are these hard to replace? its on a 94 gmc 2wd 350 5.7

Not really sure what this particular hose looks like. I assume it's a rubber line that is crimped to a metal tube with a flared nut fitting. If so just make sure you use the proper 5 sided flared nut wrench to loosen it after letting the threads soak for awhile in WD40 or similar product.

Contrary to popular belief, WD-40 is not worth a crap for freeing rusted parts. It's a water displacement spray. If you have rust, use a good quality penetrating oil such as Kroil or PB Blaster. I do agree with Zora about the wrench. It's not that tough of a job, just a little messy.
