How to Change the Thermostat on a 1995 Mitsubishi Galant

74

Although the Mitsubishi Galant is an import vehicle, its thermostat is the same type used by most domestic auto manufacturers. The thermostat is located inside the intake manifold to regulate engine temperatures. As the temperature of the Galant’s engine rises, the thermostat allows an increased flow of coolant through the engine. The fluid helps to reduce the engine temperature. When the thermostat stops working, the risk of overheating increases. This could warp the aluminum engine block Mitsubishi installed in the Galant.

Tools Used: Tools, Socket set, Towel

Change the Thermostat

Follow the upper radiator hose to the location where the radiator hose connects to the Galant’s intake manifold. The hose connects to the T-stat housing on the intake manifold. The thermostat rests inside the housing.

Remove the two bolts that hold the T-stat housing onto the intake manifold with a deep-well socket. A small amount of coolant may leak out of the hose as you remove the T-stat housing from the base of the intake manifold. To reduce the amount of leakage, hold the radiator hose in a vertical position as you pull up on the T-stat housing to drain the fluid back into the radiator.

Wipe the surface of the Galant’s intake manifold clean with a towel. Prevent debris such as leaves or gasket material from getting into the hole in which the thermostat rests.

Pull the used thermostat out of the intake manifold. Place the new thermostat into the hole, making sure the end with the spring goes into the hole. Place a new gasket over the thermostat. Place the T-stat housing on top of the gasket. Secure the housing to the intake manifold with the two bolts.

Tips & Warnings: Allow the Galant to cool down before undertaking he jobto avoid burns.
