Detailed Description

This thermostat housing assembly is engineered for vehicles that require a replacement coolant outlet with the thermostat already integrated into the housing.

Installation Notes and Tips

Confirm the vehicle’s VIN and engine application before ordering, since several listed Jaguar models use VIN-based fitment notes. Inspect the mating surfaces, replace contaminated coolant as needed, and torque fasteners evenly to help the gasket seal correctly. The package contents list the housing, thermostat, and bolts; verify the vehicle-specific service procedure before installation.
