: Coolant Overflow

07-18-04, 04:21 PM
I have a '94 Deville concours 4.6l. with a overheating problem. I have changed the thermostat and the radiator cap but my car consistantly gives off coolant from the pressure relief hose located just below the cap when the car is warm. which the gives a low coolant level reading. :hmm: Please help.

There are a lot of threads with info on this. It might be a simple overheating problem or it could be headgaskets. Have you checked the water pump belt? It's on the driver side of the engine.

After that you have to do some diagnosing.
A compression test or a cylinder test are good tests to do for this problem.
