Installation Notes and Tips

Confirm the vehicle’s engine and fitment notes before installation, especially on Volkswagen CrossFox and Volkswagen Saveiro applications with model-year-specific housing variations. Transfer or replace the thermostat and sensor only if required by the vehicle configuration, since this housing does not include a thermostat or sensor. Inspect the mating surfaces, replace the gasket and O-rings as needed, and verify the outlet port alignment before tightening the housing.
