Installation Notes and Tips

Verify the required opening temperature and compare flange and bypass dimensions before installation. Replace the thermostat only after the cooling system has cooled completely, and inspect the housing, gasket sealing surfaces, and coolant condition during service. Confirm vehicle-specific fitment for your exact year, make, and model before ordering, especially on Ford Explorer, Mazda B4000, and Volkswagen Golf or Jetta applications. Part number 13648 should be matched to the original thermostat specification for proper operation.
