Verify the outlet port diameter, mounting hole count, and neck angle before installation. Because the housing is supplied without a thermostat, gasket or seal, bolts, or O-rings, reuse or source the correct service parts for your application. Clean the mating surfaces thoroughly and inspect the surrounding cooling-system components before reassembly.
