Water pump arrived quickly and it fit perfectly with no issues. Truck started and worked so much better than the old water pump.

Bad product
Very disappointed in Atlantic British, I went with them hopping to get good Quality product.. The shipping box was in great shape but the product box was torn on the bottom and my water pump had a deep scratch right on that sealing edge ( see picture) and also the seal that came with it was torn, this will put me another week behind on my build which makes me very upset!

Disappointing quality for AB
I had a similar issue as another reviewer here, however I forgot to take pictures. Several scratches on the mating surface, but I didn't want to wait another week for a new part so I installed it anyway. Also, it comes with a cheap looking cardboard gasket that was pretty significantly warped. Had to leave it under a stack of books for a few hours to get it flat enough to install. Seems to work fine but time will tell how that holds up.Other than that, install went smooth and the truck seems to run well now with no noticeable leaks. I will update if I have issues down the road...

Died after 10k miles.
It died after 10,000 miles and 15 months. The bearings are shot and coolant started coming out of the weep hole.
