Installation Notes and Tips

Before installation, ensure the engine is cool and the cooling system is depressurized. Remove the old thermostat housing carefully to avoid damaging surrounding components. Clean the mounting surface thoroughly before installing the new Dorman 902-2033 housing with the included gasket.
