I have a 1997 5.2 Liter Dodge Ram and after I shut it off I can hear a hissing type noise. It sounds like its comming from the radiator. Does anyone know what it could be?

Sounds like the AC, has it been hot where you live???

That could definitly be it. Ill have to try not using ac and see if it still happens.

my truck was just in for an oil change and i had them check mine. i was positive it was a pin hole in the coolant system somewhere. it was in fact the leakdown of the air conditioning. the a/c system cools and de-pressurizes etc and you will hear this noise. dont worry about it!
