Thermostat for the 4.4L AJ V8 and 4.2L Supercharged V8 petrol engines, fitted within the engine cooling circuit.

The thermostat regulates coolant flow through the radiator by remaining closed until the engine reaches operating temperature, then opening to allow circulation. This gives a rapid warm-up from cold and maintains a stable running temperature under load.

Frequently asked questions

What is the V8 petrol thermostat and what does it do?
This thermostat regulates coolant temperature on the 4.4L AJ V8 and 4.2L supercharged V8 petrol engines. It holds coolant back until the engine warms up, then opens to allow flow through the radiator. The result is a faster warm-up from cold and a steady temperature once the engine is working.
Which vehicles and engines does this thermostat suit?
This thermostat suits the Discovery 3, Range Rover L322 and Range Rover Sport L320 fitted with the 4.4L AJ V8 or 4.2L supercharged V8 petrol engine. It is engine-specific, so check your vehicle runs one of these petrol V8s rather than a diesel before ordering.
How does a faulty thermostat affect the engine?
A faulty thermostat typically causes overheating when stuck shut, or persistent low running temperature and slow warm-up when stuck open. On the 4.4 and 4.2 V8 petrol engine that can mean hard-working cooling fans or weak cabin heat. A new thermostat brings coolant temperature back under proper control.
