Here are some causes for a bad coolant sensor-- rich running engine, increased vehicle emissions, engine shutdowm. if the sensor is bad, then when at normal tempurature the sensor is sending incorrect info to pcm. this sensor controls fuel and various functions. it is used to send correct info to pcm. so to compensate for engine management. have a good day !! have it scanned to find problem code. if check engine light is on.

2000 Oldsmobile alero had water in the coolant and it froze over night now it over heats and shoots the coolant out the overflow . I don't think the water pump is out. What else could be wrong?

Very serious.... don't over heat too much or your car will break..... could be the thermostat is hooped... or the water pump.... make sure the car is completely thawed.... but i'd she over heats take her to the mach.... night cost a few bucks but no car costs a lot more
