Frequently asked questions

What does the Thermostat do?
The Thermostat regulates coolant temperature on the Jaguar V8 petrol engine. Mounted in the thermostat housing at the coolant outlet, it stays shut until the engine reaches operating temperature, then opens to let coolant flow to the radiator and hold a steady running temperature.
What are the signs of a failing thermostat?
A failing Thermostat on the Jaguar V8 typically sticks shut and overheats the engine, or sticks open so it runs cool and warms slowly. Erratic temperature readings and weak cabin heat are common clues. Overheating from a stuck-shut unit can cause serious engine damage.
Which models and VIN ranges does this thermostat fit?
This Thermostat fits the Jaguar S-TYPE (1999-2008) 4.0L V8 NA to VIN M45254, XJ (X350, 2003-2009) 4.2 supercharged VIN G00442 to H32732, XJ (X308) 3.2/4.0L except supercharged VIN 812317 to F59525, and XK8 VIN A00083 to A30644. Confirm with your VIN.
