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.

The part was an exact match, and bolted up perfectly the video was a huge hel

your video on how to do it yourself convinced me to purchase from you.

OE vs. Aftermarket

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.

Fits perfect

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.

Pump works great. No leaks or overheating.

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.

runs quieter

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.

Perfect fit

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