Replace the failed and leaking water pump on your Land Rover, Range Rover or Defender with our new, original equipment (OE) water pump replacement (Part # STC4378OE). The OE distinction means this water pump meets the same quality standards of the part used on the assembly line when your Land Rover was made. Accordingly, our OE Land Rover water pumps are made to the exact specification of your Land Rover Discovery II 1999 – 2004, Discovery I 1994 – 1999, Defender 90 1997, Range Rover 4.0 and 4.6 1995 – 2002 and certain model Range Rover Classics. This water pump also features a quality, OE gasket – a simple but important feature that will lengthen the lifespan of your water pump.

The water pump is a central component of the Land Rover Engine Cooling system. When your water pump fails or leaks, that’s a sure sign that your belts, hoses, viscous drive and thermostat should be replaced as well (You’ll have to remove them to reach your water pump anyway!). Get it all done at once and you won't have to worry about them for another 60k+ miles.
