Frequently asked questions

What is the Thermostat Housing Gasket (1341370) used for?

The Thermostat Housing Gasket seals the thermostat housing, or water outlet, to the engine on the 2.7 TDV6 diesel, stopping coolant leaking at that joint. It fits Land Rover Discovery 3, Discovery 4 and Range Rover Sport with the 2.7 TDV6. Land Rover part number 1341370, also listed as 9L438.

How many gaskets are needed to reseal the thermostat housing?

You typically need one Thermostat Housing Gasket per housing on the 2.7 TDV6. Fit a new gasket whenever the housing is removed, as the old one usually won't reseal. If you're also replacing the thermostat's own seal, that's a separate O-ring.

Can the thermostat housing gasket be reused?

Replace the Thermostat Housing Gasket every time the housing is removed. Heat cycling and coolant typically harden the old gasket, so it won't reseal and can weep coolant at the joint. On the 2.7 TDV6 it's standard to renew it during any thermostat or housing work.

How do I confirm this fits my 2.7 TDV6?

This gasket fits the 2.7 TDV6 diesel in Discovery 3, Discovery 4 and Range Rover Sport. Match it to Land Rover part number 1341370 (alternative 9L438) and confirm your engine is the 2.7 TDV6. It seals the thermostat housing/water outlet, not the thermostat itself.
