i got a strange leak on my truck i havent gotten into it too much but it leaves a little spot under whenever i park. its dripping off the ac compressor. what could the leak be coming from?

Color? smell? consistancy? have you been running your a/c before you park? if you need ppl to diagnose you need to be as specific as possible.

 

Your AC compressor could be causing water to condense on the outside of it. The water then drips onto the cement below you car when it is parked. Actually, it is always dripping, but your truck is in motion so you can't see it accumulate. Actually crawl under your truck and catch some of the dropping liquid (if it isn't hot). If it looks, smells, and yes... tastes like water, you're all good. If you are looking at it on the concrete, it may have some oil in it from the parking lot surface and it could mislead you as to what it is.

Another thing to look for... If the liquid only leaks after running the AC or during the operation of the AC, then it's probably condensation. If it drips with the truck running, but without the AC having been used in the last few hours, then it is probably something else. If it quits dripping immediately after you shut your truck off, it isn't condensation.

 

guess i forgot the most important part, its oil.

 

Possibly the oil filter adaptor gasket where the part that you screw the filter into is bolted to the block. Mines leaking now but I'm out of town for 30 days and havn't had it fixed. From what I
ve read, this is a pretty common oil leak. Tracka96

 

Sounds to me like PAG oil from the compressor. The compressor has 8 ounces of clear oil to lubricate it. If it is pag oil and leaks out your compressor will die the "black death", freeze up, and take your serpentine belt out and the idler pulley with it and leave you on the side of the road.
