Installation Notes and Tips

Verify the vehicle application and compare the port diameters, bolt spacing, and mounting-hole layout before installation. Transfer or replace the thermostat, gasket, seal, and bolts as required by the vehicle service procedure, since they are not included with this housing. Bleed the cooling system after installation using the housing’s air vent to help remove trapped air and restore proper coolant circulation.
