The PCH500040 heater hose assembly is designed to manage coolant flow to and from the heater core on your Land Rover Discovery II (1999–2004), ensuring proper cabin heating and cooling system operation.

Over time, heater hoses can become brittle, crack, or leak due to constant exposure to heat and pressure. A failing hose can lead to coolant loss, poor heater performance, or even engine overheating. Replacing the hose assembly restores proper coolant circulation and helps maintain both engine temperature and interior comfort.

This complete hose assembly connects the heater inlet and outlet, providing a direct replacement solution for worn or damaged original components.

Replaces part number JHC100410.

Ideal for repairing coolant leaks, restoring heater performance, and preventative cooling system maintenance on Discovery II models.
