The thermostat on your vehicle controls the flow of coolant based on temperature. When you just start your engine, the thermostat remains closed to accelerate the warm up process. After a few minutes, it opens up to allow the warm fluid to flow. If your vehicle is overheating but not blowing warm air from the heater, the problem is more than likely your thermostat. If the thermostat gets stuck closed, it allows no fluid to flow and ends up overheating the coolant already in the engine. To fix this problem and get your vehicle's heat restored, replace your thermostat. Complete assembly, including housing.
