Frequently asked questions

What is the LR023145LR O-ring for?
The LR023145LR is the sealing O-ring for the thermostat housing on the 4.4L V8 diesel (TDV8). It seats between the thermostat housing and its mating face to seal the coolant joint, keeping the cooling circuit leak-free where the housing bolts up.
When should this thermostat housing O-ring be replaced?
Replace this O-ring whenever the thermostat or its housing is removed on the 4.4L V8 diesel. Old rubber O-rings rarely reseal once disturbed, so fitting a new one during a thermostat job prevents coolant weeping from the housing joint.
Which vehicles does this O-ring fit?
This thermostat housing O-ring fits the 4.4L V8 diesel in the Range Rover L322, Range Rover L405, Range Rover Sport L320 and Range Rover Sport L494. It's specific to the TDV8 cooling system, so confirm your engine before ordering.
