Does engine overheat at idle, or when driving?
Customer: replied 5 years ago.
at idle. i havent driven it yet. it takes about 20 minutes to overheat and fans are working
Not likely that the radiator is totally stopped up. You can confirm this by taking radiator hoses loose and flushing water through the radiator with a garden hose. The most common problem on this engine with overheating is head gasket leakage. You will not normally experience any coolant in the oil or pressure loss of the cooling system. What will normally happen is that with the engine running, the combustion pressure pushes combustion gases into the cooling system, causing the engine to overheat.

Hello! Welcome to justanswer!

Thats a sign of a bad water pump. However if you take out the pump and its impeller is good, the last experts answer is right. Also on the net a few places sell head stud kits that fix your problem permanently. Just google Deville Head Stud kit.
