Frequently asked questions

What is the Thermostat Assembly and what does it do?
The Thermostat Assembly regulates coolant flow on the Land Rover Defender 2.4L Duratorq TDCi diesel. It brings the engine up to operating temperature quickly and holds it there, opening to let coolant flow to the radiator as the engine warms. It's mounted in the oil cooler and filter housing.
Which Defender does this thermostat fit?
This thermostat fits the Land Rover Defender 2007-2016 with the 2.4L Duratorq-TDCi (140PS) diesel, up to VIN 7A744122. Later vehicles from that build point use a superseding part, so check your VIN against the ceiling before ordering.
What are the signs the thermostat needs replacing?
A failed thermostat typically shows as slow warm-up, a temperature gauge that won't reach normal, or overheating if it sticks shut. On these Defender diesels a stuck thermostat upsets running temperature. Replacing it restores proper coolant regulation.
