Frequently asked questions

What does the thermostat housing O-ring do?
The thermostat housing O-ring seals the coolant joint between the thermostat/water outlet housing and the engine on Jaguar 3.0L supercharged V6 and 5.0L V8 petrol units. It stops coolant leaking at the water outlet where the thermostat controls flow to the radiator.
When should this O-ring be replaced?
Replace the O-ring whenever the thermostat or water outlet housing is removed. It's typically a single-use seal, and reusing a compressed O-ring often leads to coolant weeping at the joint. Fitting a new one each time the housing comes off is the reliable approach.
Is the thermostat included with this O-ring?
No, this is the O-ring only, not the thermostat or housing. It's the coolant seal that sits between the thermostat housing and engine on the Jaguar V6 and V8 petrol. If you're replacing the thermostat itself, order that separately.
