I have a 2002 Honda Civic with 59,000 miles.Last weekend it overheated.There was water in the overfill container.I let it cool down,then added water.It stayed in ad didn*t overheat again.My mechanic thinks it could be the thermostat,but I didn*t tink that would cause it to overheat?

Dear Karen,
First of all, you should always use a 50/50 mix of water/antifreeze for your cooling system. Water has a much lower boiling point and could overheat faster.
As for the thermostat being bad, that could certainly cause your vehicle to overheat. If the thermostat stays closed then the coolant is never allowed to circulate into the radiator to cool down and the vehicle may overheat.
The therostat is definitely a possiblity.
