Thermostat could be stuck in the closed position??? Frozen coolant is not as big of a problem as you guys make it. Unitl this weekend, I have been freezing water in the system all winter. I finally added some coolant to the mix this weekend. Upon startup, the engine is cold and does not need coolant. When the engine warms up and needs it, it is usually thawed out (engine heat). If you want proof, come over to Hopkins and I can show you. My laser wasn't driven thursday and friday (2 coldest days in MN). I took it in the garage (non-heated) Saturday and started it and let it run at idle. I watched the gauge and the engine to make sure it didn't overheat. I added some coolant to the frozen water and the car did not even come close to overheating. Maybe it only reached temps of 15 below 0 in Hopkins huh??? The car warmed up and no problems with overheating were discovered. You can take a look and determine weather the coolant is frozen though. Feel the hoses and check the overflow. Have you replaced the thermostat before?
