Installation Notes and Tips

Verify the vehicle’s engine coolant outlet housing style before ordering, especially on 2001 Ford Explorer, Explorer Sport, Explorer Sport Trac, and Ranger models with threaded sensor style notes. This kit is supplied without a thermostat, so reuse or replace the thermostat separately as needed. Clean the mating surfaces thoroughly before installation and confirm the inlet diameter and mounting flange dimensions match the original part.
