Water pump Gates or Pierburg

I'm working on adapting these water pumps to a variety of older engines. This one will be going on a Chevy LSx. The pumps support two different control schemes; one via PWM (no feedback) and one via LIN. I will be working on reversing the LIN communications and building a more sophisticated controller soon.

Gates all the way. I have just a basic timing kit and water pump and i auto-x mine in the summer. Haven't had a single little problem so far.

PIERBURG makes a good water pump...

Once I removed the thermostat, I felt in the port and although the impeller felt ok, it spun freely; not smooth like a bearing but rough like it was dragging. Since I was able to freely turn the impeller through the thermostat hole, I have to assume my water pump is failed.

Gates is crap. Bought their water pump and it failed less than a year and leaked the whole time.

Mine broke in less than 500 miles and their replacement broke too (which I paid for till I returned them the faulty one back) in less than 500 miles on an Audi A1. Now they have my money for 2 water pumps and I paid for labour costs of replacing twice, and waiting for a refund decision for more than a month. AVOID!!!

Don’t use a Gates kit or if you do purchase the Gates kit without the water pump and get a different brand water pump. Gates water pumps have an enormously high failure rate in the last several years and it sucks to have to do the job twice.

Water pump failed on the gates timing belt kit and engine shredded only 16000 miles on it

Gates water pump failure

I have seen early failure with the Gates water pump and wont use them.
