Hi, I'm new here. My wife's '98 astro 4.3L 2WD has started leaking oil. The guy at the Jiffy Lube told her that it was leaking from the oil cooler line. What's involved in fixing this? I can get the part for around $50-$60 on RockAuto, but wonder if I may need a lift to do the repair. If so, I may need to take it to my mechanic, but cash is in short supply. Thanks!
