Re: Oil contamination in cooling system-Any ideas?
Pretty uncommon problem thats for sure, head gasket would make sence.
If you bought it used, I would keep an eye on it, the oil should float on the coolant so you should be able to see an accumulation in the overflow or in the filler neck if it is crossing over... I havent done much cooling system work on the 5.7l wk grand my only other guess would be an oil cooler failure (IF it were internal to the radiator, and i dont think there even is one on the grand).
