Its really not too bad. On my 96, the easiest way is to drop the front skid plate, and use about 3' of 3/8" extensions to get to the rear bolt. On some, the lines will pull right out - on some (like mine) you have to jack the engine up slightly in the chassis to create enough room to remove the lines. The filter-to-radiator set are easy, just don't lose the clips or o-rings.

On my 2wd it was very easy, I did it in about 45 mins including oil change and greased the thing. I had a hell of a time with the one line needing bent a little bit but it wasnt too bad. Check www.rockauto.com for them they showed up next day! I ordered at 12:45 they showed up at my house by 2:30 the next day. I got the dorman brand they are sussposed to be good.

here's one that works, looks like a %5 discount.
Better than nothing... 3B5CEFC2693A


Ordered both lines from the filter to the block, & from the rad to the filter.
total came to like $48 with the cupon code, and $7 shipping. What I like about these is that they come with the little crush gaskets.

I am having them replaced at a shop today, actually. I replaced them myself about 30,000 miles ago and sure enough, they are leaking AGAIN! I don't want to replace them again because I am a slack ass, so the local shop is doing it for $350 (ouch).

Any reason why GM is stupid and hasn't manufactured replacements that don't leak?
