Frequently asked questions

What does the Thermostat do?
The Thermostat regulates coolant temperature on the Jaguar V8 petrol engine. Fitted in the thermostat housing at the coolant outlet, it stays closed until operating temperature is reached, then opens to allow coolant to the radiator, holding a stable running temperature.
What are the symptoms of a failing thermostat?
A failing Thermostat on the Jaguar V8 typically sticks shut, causing overheating, or sticks open, leaving the engine slow to warm and running cool. Look for erratic temperature gauge behaviour and poor heater output. A stuck-shut thermostat that overheats the engine risks serious damage.
