Not all water pumps are the same and you typically get what you pay for.

What makes this Original Equipment water pump a best bet for your Land Rover Discovery Series II 1999 – 2004, Discovery I 1994 – 1999, Defender 90 1997 or Range Rover 4.0 and 4.6 1995 – 2002?

  • Orginal Equipment means manufactured quality by the genuine manufacturer, just not in a "genuine" box, saving you money!
  • Quality internal bearing and housing (lesser pumps have cheap bearings that can often seize-up much faster over time)
  • A quality OE gasket that is durable and long lasting (compared to other pumps manufactured with non-spec gasket materials that can often degrade and begin to leak in a short period of time)

This new, original equipment (OE) water pump is a direct replacement for Part # STC4378 built by the genuine manufacturer to exact specifications. 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 or Range Rover.

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.

To be honest owning a Discovery 2 was a worrisome ordeal what my water pump went out. thinking that this issue would be expensive and had to replace I was scared. However AB sent me a great quality water pump at a great price.

I replaced the original pump with an aftermarket unit at 150k miles. Just replaced the aftermarket pump with this OE pump at 270k miles. 30k mile difference...not bad. To be fair the aftermarket pump had not "failed" yet. There was an uncomfortable amount of shaft play and I was in the process of changing the timing gears/chain. The OE pump definitely appears to be higher quality. The pump craftsmanship & hardware is more impressive than the aftermarket replacement (thicker reiforced vanes and smooth internal surfaces). The aftermarket pump still had gouges on the inside where the pump had failed prior to being remanufactured. I had no issues with the installation.

It's a water pump that pumps water that all I can say about the pump. When I got it the factory had packed the gasket in a poor position and it had a tear in it. I called AB and they express shipped me a new one. Can't say enough about the service from AB.

This pump came with a really nice gasket. High quality pump. The impeller is no longer brass, but steel- to save future buyers a little confusion. No leaks or overheating.

There is a difference between water pumps. The one which I replaced had a steel impeller. The one from Atlantic British had a brass impeller, which actually makes the part run quieter. Since installing the part, I have drove over 8,ooo miles, from Michigan to Arizona and back twice pulling a 7,ooo lbs pay-load, with NO problems at all, I am very impressed at the quality of the parts that I have ordered from AB.

Nothing can really be said about a water pump, it pumps water. Fits right, easy install as far as water pumps go.

Bought this water pump while on sale. This price matched the lowest anywhere I could find. This pump has a bronze impeller and looks to be significantly better than the one I replaced. No leaks and engine is cool.
