∙ 16y agoOverheated engines often cause the head to warp, resulting in a blown headgasket. If the engine blows out the coolant, you have a bad head gasket/warped head. If you're getting coolant in the oil, same thing. If one or two cylinders have very low compression, same thing.
It's not news that anyone wants to hear, but I'd check that first since it's a very common condition after an engine overheats.

∙ 16y agoIf it is leaking coolant. And you changed the thermostat. I would then move to this section. Flush the radiator and the heater core. This can be done at a certified shop with a reliable mechanic.
Flush your radiator coolant and replace thermostat
You might have bad actuator that opens and closes airways.
Check the radiator for full coolant. Check the engines water pump and thermostat, as the engine coolant carries heat from the engine into the heater core.
Blown head gasket?
You could have a bad water pump causing no coolant flow, inoperable radiator fans, a coolant leak,............
The thermostat.
The function of a car thermostat is to ensure that coolant gets to the radiator when it should. It blocks the coolant from reaching the radiator when the radiator is cold, and then lets it flow once it is heated up.
No. The thermostat controls the flow of water through the radiator, not the heating core. Using a thermostat with a higher temperature rating delay the opening of the thermostat (and the flow of water to the radiator) until that higher temperature is reached. This will cause the coolant to run hotter.
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.
The thermostat regulates coolant flow through the radiator by opening and closing based on the engine temperature. When the engine is cold, the thermostat remains closed to allow it to warm up quickly. As the engine heats up, the thermostat opens to allow coolant to flow through the radiator and dissipate the heat.
If there is no fluid coming from the radiator to the thermostat housing, it could be due to a blockage in the coolant system, a faulty water pump, a stuck thermostat, or low coolant levels. It is important to investigate and address the issue promptly to prevent overheating and potential damage to the engine.
