Thermostat Housing - engine cooling circuit component for the 3.0L Ingenium six-cylinder petrol engine (AJ20P6 / AJ22P6).

The housing carries the coolant thermostat and forms the junction between the cylinder head coolant outlet and the radiator and heater feed connections, controlling flow through the radiator so the engine reaches and then holds its operating temperature. Supplied as a complete thermostat and housing assembly.

Common failure modes are a leak at the housing or its hose spigots and a thermostat that sticks open or closed, giving slow warm-up, coolant loss or overheating.

Frequently asked questions

What is the Thermostat Housing used for?
The thermostat housing holds the engine thermostat and routes coolant on the 3.0L AJ20P6 petrol engine. This OEM housing helps control coolant flow to regulate engine temperature, directing coolant to the radiator once the engine reaches operating temperature.
Which vehicles and engine does this housing fit?
This thermostat housing fits the 3.0L AJ20P6 petrol High engine in the Discovery 5 2017+, New Defender 2020+, Range Rover L460 2022+, Range Rover Sport L461 2023+, and Velar 2017+, from the Nitra plant build. Confirm your engine and VIN against the noted breaks before ordering.
Does the housing usually come with a new thermostat?
Thermostat housings on these engines are often supplied as an integrated housing with the thermostat built in, replaced as one unit. Check the product images and description for exactly what's included, since fitting a complete housing avoids separating a sealed assembly.
Why do thermostat housings fail on these engines?
Thermostat housings typically fail when the plastic housing cracks or the seal leaks coolant, or when the thermostat sticks and causes overheating or a slow warm-up. Common signs are coolant loss, a temperature warning, or visible weeping around the housing.
