Technical specifications

Installation requirements

Let the engine cool completely before starting. Clamp or drain coolant hoses, disconnect the electrical plug, and swap the valve, making sure hoses are fully seated with secure clips. Top up with the correct coolant, bleed the system and check for leaks. Electrical and cooling repairs are best carried out by a qualified technician.

Before replacing the valve, check the wiring, connector and fuse supplying it, as electrical faults can cause similar symptoms.

Fitment checks before ordering

Confirm the OE number on your existing valve and verify by VIN before ordering.
