Is the thermostat in my 2001 chevy malibu bad or just not strong?
I just drove 25 miles and my heater was still blowing cool air but my temperature gauge never went more than a hair above thee 100 mark it is at when I started it. car ran fine all the way without hesitations or over heating. if the thermostat is bad wouldn't the car overheat or is that only when the radiator is low? shouldn't the temperature have been a little higher than just barely above the start up mark even under normal driving conditions? is the thermostat just not strong enough for this below zero weather? Just bought this used car so don't know much about it but have had cars in the past that have overheated and broke down on the way to or from work a lot. only been driving it for a week. don't know about thermostats so wanted to know if a bad one only meant the inside of my car will not be warm or will the engine overheat like when the radiator is low or coolant level wrong and it is blowing cold air into the car for that reason.
