Frequently asked questions

What is the JHB100590LR heater water hose used for?
The JHB100590LR is the heater inlet hose on the Land Rover Defender 2.5L 300 Tdi. It carries hot coolant from the engine to the heater matrix, feeding the cabin heating system. Genuine Land Rover part number JHB100590.
Where does this heater hose sit on the Defender?
This heater hose runs between the engine cooling circuit and the heater matrix at the bulkhead. It typically routes across the back of the engine bay to the cabin heater feed on the 300 Tdi.
Is this the inlet or outlet heater hose?
This is the heater inlet hose, which feeds coolant into the matrix. The matching outlet hose is a separate part, so check whether you need the inlet, outlet, or both before ordering.
Why do heater hoses fail on the 300 Tdi Defender?
Heater hoses perish, crack, or soften with age and heat cycling, leading to coolant leaks and loss of cabin heat. Replacing a hard or weeping hose prevents coolant loss and overheating.
