Installation Notes and Tips

When installing the Dorman 902-5073 thermostat housing, ensure the mating surfaces are clean and free of old gasket material to achieve a proper seal. Use the included gasket and torque mounting bolts to manufacturer specifications. Since the thermostat is not included, verify the condition of the existing thermostat and replace if necessary. The 180-degree housing neck angle should align with the vehicle’s coolant hoses for a correct fit. Bleed the cooling system after installation to remove any trapped air through the integrated air vent.
