Hi guys. My 03 h2 had some oil drips under the drivers side front almost under the headlight area. After popping the hood and checking it out I see that the two lines going into the radiator drivers side top...appear to be the culprit. Do I change the fittings or the whole line. Looking for any help and encouragement. Thanks

 

Oil cooler does not go into the radiator. its a separate cooler in front of the radiator. In any event, have you tried to tighten the fittings yet?

I am fairly certain the oil cooler is integrated in the radiator on the driver side and the tranny on the passenger side of the radiator. The external radiators, the small one is a power steering cooler and the one in the middle is the tranny cooler.

 

LoJac is correct. The oil cooler is in the radiator. I suppose it could be the 0 ring inside the fitting. I would replace the lines with GM parts if you suspect the lines have a leak. You do not want to have one blow while driving. Since I don't use my H2 for towing anymore, if my lines went bad, I think I would remove and bypass them.

 

I watched it forever last night till I finally saw it drip. It's coming out around the line right at the fitting. Can the fitting be replaced or do I need to replace the whole line. How hard is it to bypass?
