I have a 1973 std beetle. The thermostat is frozen in the compressed (unexpanded) postion. I have an new one ordered; but, I don't understand the exact workings of this device. Does this unexpanded condition mean the blower doors are closed and thus cause overheating of the engine? After removing the thermostat mounting bolt, the unit was pulled up by the rod going to the doors. Since I can pull down and operate the doors, I assume they will be working fine with a new unit.
Am I correct in my assumptions?
