Frequently asked questions

What does the Thermostat Cover do?
The Thermostat Cover encloses the thermostat at the coolant outlet of the 3.2 and 4.0L V8 naturally aspirated engine. It locates the thermostat and forms the sealed outlet where the top hose connects, directing coolant to the radiator once the thermostat opens.
When is the thermostat cover replaced?
The Thermostat Cover is typically replaced if it's cracked, corroded or leaking at the outlet, or when servicing the thermostat behind it. On older V8s the cover can weep coolant at the hose neck, so it's worth checking when the cooling system is apart.
Which models and VIN range does this cover fit?
This Thermostat Cover fits the Jaguar S-TYPE (1999-2008) 4.0L V8 NA up to VIN M45254, and the XJ (X308) 3.2/4.0L V8 except supercharged, VIN 812317 to F59525. Use your VIN to confirm the build range before ordering.
