Frequently asked questions

What is the LR010800 O-ring used for?
The LR010800 O-ring is a genuine Land Rover sealing ring between the cylinder block and the water outlet tube at the thermostat housing. It's used on petrol engines only and keeps coolant sealed at that joint.
Where does this O-ring sit on the engine?
This O-ring seals the cylinder block to the water outlet tube, around the thermostat and coolant housing. It fits petrol 5.0 V8 (AJ133) and 3.0 V6 supercharged engines across the Discovery 4 and 5, new Defender L663, Range Rover L322 and L405, and Range Rover Sport.
Should the O-ring be replaced every time it's disturbed?
Yes, this O-ring is typically single-use. Once the water outlet joint is opened, fit a new ring rather than reusing the old one, as a compressed seal can leak coolant. It's standard practice to renew it during any related repair.
