Oil light comes on going up mountain, fan motor on when stopped Radiator noise.

I think your onto something. My wife is not the best at discribing what is going on! I questioned her several times and then it gets confusing! :)

I know EXACTLY what you mean! Hope mine isn't looking over my shoulder. LOL! The going up the mountain thing and oil light don't add up! Should have the same problem anywhere if it were pressure or wiring related.

Yes, it doesnt make sense, maybe I am not getting the right picture from my wife. I dont think she knows what those red lights are!!

Thanks for your input....will check on this. I meant new valve cover gasket and seals, not new head gasket. I check the exhaust, smells normal, oil looks good, and anti freeze looks normal as well. I did a pressure check on the cooling system 17lbs slowly leaked down over a 20 minute period. The mechanic said it could have leaked from the radiator cap, because the pressure test converter might have leaked some, not a tight fit.
