...thermostat gasket.? Now it is overheating all the time. I didn't have this problem before. I have tried having another thermostat installed, and it still overheats. Everything appears to be working. Any suggestions?
I have a 2000 Pontiac Montana that took to repair shop to replace a leaky...

You may have an airlock in your cooling system

I agree with the hound. The system was probably not purged correctly. If you look at the thermostat housing there is a small brass screw in the top of it. This needs to be open to fill the system since it is the highest point. You can try opening it now and see if the air will purge, but you may also have to drain and refill the system with this open.

sounds airbound, start the engine and open the bleaders up until a steady flow of coolant flows out. One beader is on the coolant tube on the front of the moyor to the left and the other is on the thermostat housing.try the one on the coolant tube first.

Airlock is the likely culprit - however, are you sure the thermostat was re-installed with the correct orientation?
