- Carefully remove the old thermostat and gasket, making sure to note the orientation of the thermostat.
- Clean the surfaces of the housing and engine block to remove any old gasket material.
- Install the new thermostat in the same orientation as the old one, with the spring side facing into the engine.
- Apply a small amount of gasket sealer to the new gasket and place it on the housing.
- Reinstall the housing and bolts or clips, being careful not to overtighten.
- Refill the radiator with the correct type and amount of coolant.
It’s important to follow the manufacturer’s recommendations for the type of coolant to use and the proper torque specifications for the thermostat housing bolts. If you are not comfortable performing this repair yourself, it’s always best to consult with a qualified mechanic.
