Water Valve - coolant control valve in the auxiliary fuel-fired pre-heater circuit.

The valve opens and closes the heater loop against the main engine cooling circuit, directing coolant through the fuel-burning pre-heater so it can warm the coolant and the cabin independently of the engine running. It is fitted only to vehicles specified with the fuel-fired heater (park heating) option.

A valve that fails to open leaves the pre-heater unable to circulate warmed coolant and the heater will shut down on over-temperature; one that fails to close allows heat to bleed away into the engine circuit, extending warm-up time.

Frequently asked questions

What is the Water Valve (LR167749) used for?
The water valve controls coolant flow in the auxiliary fuel-fired pre-heater, or park heater, circuit. This Bosch OEM valve directs warmed coolant when the fuel-fired heater runs, letting the cabin and engine warm up before driving in cold conditions.
Which vehicles use this pre-heater water valve?
This water valve fits Land Rover models with the fuel-fired park-heater option: New Defender 2020+, Discovery 5 2017+, Range Rover L405 2013-2022 and L460 2022+, Range Rover Sport L494 2014-2022 and L461 2023+, and Velar 2017+. Only vehicles specified with the pre-heater have it.
How do I know if my vehicle has the fuel-fired heater?
Only vehicles ordered with the fuel-fired heater or park-heat option use this valve, so it isn't fitted to every listed model. Look for an auxiliary heater unit in the engine bay or under-body, and use your VIN to confirm the option before ordering.
Why does the heater water valve fail?
Heater water valves typically fail when the internal valve sticks or the electric actuator stops responding, leaving the pre-heater unable to circulate coolant. Symptoms usually include the park heater not warming the cabin or a coolant leak at the valve.
