hello guys, im new to the forum and could use some help. I recently bought a 79 cutlass, and it has no rust and all the glass is good. The body was sanded and primered. The car has NO bondo anywhere and no dents. Odomator reads 45,*** i do not know if it turned over or not. The motor is a 260 v8 that runs good while it is being ran at idle, but when ever i shut it off after about 20mins or so the radiator starts to steam and i can hear a bubbling noise that sounds like it is coming from the reserve tank. Can anyone give me an opinion of what they think might be causeing my radiator to get so hot and why the bubbling noise? Thanx in advance guys!!
