Frequently asked questions

What does the LR100353LR O-ring do?
The LR100353LR O-ring seals the upper joint of the thermostat housing on petrol engines, keeping the coolant circuit leak-tight where the housing meets the engine. It's a Genuine Land Rover seal fitted to 3.0 supercharged V6 and 5.0 V8 petrol applications.
Which engines and models use this thermostat housing O-ring?
This thermostat housing O-ring fits the 3.0 GDI supercharged V6 petrol and 5.0 V8 petrol engines, covering Discovery 4, Discovery 5, Range Rover L405, Range Rover Sport L494 and Range Rover Velar. It's for petrol engines only, not diesel.
Can the O-ring be reused when refitting the thermostat housing?
Replace the O-ring whenever the thermostat housing joint is opened. These coolant seals are typically single-use; the rubber takes a set once compressed, so refitting an old ring usually leads to a slow coolant weep at the housing face.
