Frequently asked questions

What does the thermostat housing seal do?
The thermostat housing seal fits between the thermostat housing and its mating face on the engine cooling system. It prevents coolant leaking at the joint where the thermostat regulates flow into the cooling circuit. It's for AJ-Series V8 petrol engines.
Which engines and models does this seal fit?
This seal fits AJ petrol V8 engines: the 4.4 V8 on Discovery 3 (2005-2009), and the 4.2 V8 Supercharged and 4.4 V8 on Range Rover L322 (2002-2009) and Range Rover Sport L320 (2005-2009). L322 fitment applies from VIN 6A000001.
Why does the thermostat housing seal fail?
The thermostat housing seal fails as it hardens and loses elasticity with heat cycling, leading to coolant seepage at the housing joint. A common sign is coolant loss or residue around the thermostat housing. Replace the seal whenever the housing is disturbed.
Should this seal be replaced when opening the thermostat housing?
Yes, replace the thermostat housing seal any time the housing is removed. Once compressed and heat-cycled, a used seal often won't reseal reliably, so fitting a fresh seal on reassembly helps avoid coolant leaks on these AJ V8 engines.
