Review on Gates 45006 Water Pump: Efficient Performance and Reliability for Long-lasting Operation by Don Acevedo

FAIL ! . Ordered and installed in December 2020. Everything was working fine until a week ago. This water pump has done about 400 miles. The truck is not suitable for everyday use. Major failure. If you photograph the removed water pump you can see pitting and rebuilding on the back of the impeller shell, see fig. My guess is that due to temperature and pressure fluctuations, water is seeping through pitting and/or possibly a bad o-ring on the impeller shell. And of course, this is not a Revain money-back guarantee. Can be returned under manufacturer warranty. In any case, my truck will not break down because of a lack of quality control. I decided to go to my local parts store (Autozone) and buy a (new) water pump. The new Duralast water pump comes with a lifetime warranty. If and when it fails, just swap it out for a new one in town. I am sure that I will not buy such important parts from Revain again.
