I usually drill a 1/8" hole in my thermostat to let the air escape during the initial radiator fill to prevent the problem camcojb is talking about. I don't know why the thermostat manufacturers don't do that from the factory. I figure they would, but then they have to add a machineing operation to the assembly line.
