over heating 1996 Dodge Intripid

I have replaced three thermostats; replaced the radiator and the car still over heats. Now the AC isn't blowing cold air. Why is the car overheating???? Help I am desperate.

Sounds like you may have a leaking head gasket.
Does your coolant get a lot of air bubbles in it and then start boiling?

No in fact it doesn't boil over. After I had the radiator replaced, it over heated on the first drive. The air conditioner also stopped blowing out cold air.

does it overheat when driving or when you sit at a light? If sitting at a light, your cooling fans could be shot and/or wiring/relays, etc. If it's overheating while you're driving, I agree w/ neon rt; check your motor oil and see what color it is. If it looks like cappucino or a light brown color, your head gasket is blown.

You might have an air pocket in the cooling system still.Air is an enemy of the cooling system.There is a bleeder screw on the thermostat housing.The size is 3/8 and use a very good 6 point socket with a hand ratchet.The A/C,you have a leak that can be hard or easy to find or low on freon
