Genuine: Original manufacturer part. This product is the original part designed and produced by the vehicle manufacturer.
O-Ring seals the thermostat housing on the K Series 1.8 and KV6 2.5 engines.

It sits at the joint between the thermostat housing and outlet elbow and the cylinder block, maintaining a leak-tight seal in the engine cooling circuit. It is renewed whenever the thermostat or housing is disturbed, so the joint reseals and coolant does not seep.

Frequently asked questions

What is the CDU3858LLR O-ring used for?
The CDU3858LLR O-ring seals the thermostat housing on the engine cooling circuit. It sits at the joint between the thermostat housing, outlet elbow and cylinder block, keeping the joint leak-tight so coolant doesn't seep. It's a Genuine Land Rover seal for the K Series and KV6 engines.
Should the O-ring be replaced when the thermostat is changed?
Replace the O-ring whenever the thermostat or housing is disturbed. Once it's been compressed in service the rubber takes a set and may not reseal, letting coolant weep from the joint. Fit a new O-ring each time the housing is opened.
Which model does this thermostat O-ring fit?
This thermostat housing O-ring fits the Land Rover Freelander 1 (1996-2006) with the K Series 1.8 or KV6 2.5 engine. Confirm your engine type before ordering, as the cooling layout differs between the four-cylinder and V6 units.
