Installation Notes

Verify the inlet diameter, mounting flange width, and overall height against the original part before installation. Clean the mating surfaces thoroughly, inspect the hose connection for wear, and replace any damaged coolant hoses or clamps during service. Because this unit is supplied without a thermostat, reuse or replace the thermostat separately as needed for the vehicle repair.
