There are several things that can cause your 1992 Mitsubishi Eclipse to overheat. A malfunctioning water pump or a blown head gasket should be the next things that are checked.
Change your thermostat.
The thermostat on a 99 Mitsubishi Galant is changed by draining the coolant, removing the upper radiator hose, and unbolting the housing. The thermostat can then be removed and a new one put into place.
Each 60K miles.
Sell It!!!!!
your heater will be cold, or your engine can over heat. your car can take a long time to heat up. Your inside heater will be cool, or your engine temp. will over heat.
water pump
every 60 000 miles
My 2001 Nissan frontier 3.3 v6 engine is overheating. I changed the thermostat but it still overheats.
Change the thermostat. lol. Simple but the water pump wont work if the thermostat is stuck closed. Good luck. Kyle
Blown head gasket?

Check the thermostat to see if it was installed correctly. They can get put in backwards.
