Water pump Gates or GRAF

Had gates on my 06. PITA to replace but never failed, good gasket, ok bearing.

GRAF makes this particular pump without the magnetic impeller, and it’s the best option.

I used a Gates kit which seemed good quality and included a water pump, tensioner and idler pulleys.

Graf is good. They are an OEM (original equipment manufacturer)

I run a Graf pump myself for about 2 months now and it's working fine so far.

Last time I got a new Gates water pump (made in china) the flange position on the shaft was a little different than my old one but it was close enough.

I recently installed a Gates timing belt kit with pulleys and water pump in my 2001 Forester. Unfortunately, the water pump where it mates to the engine was not machined completely flat and had a very small leak. I ended up having my mechanic remove it and put a stock Subaru one in while he was working on my clutch.

Gates pump on my Chevy 5.3 lasted a year and half. That's bullshit.

Installed a Gates water pump on a Toyota Rav4 with a V6. Needed it now and couldn't wait for an OEM or Aisin one from Rockauto. I should have waited because this pump didn't last two months before pissing coolant.

Gates water pumps failed on both my friend's Toyota Echo and my Sienna, his after under a year and mine in about 2 years. Less than 3,000 miles on my Sienna since pump was changed. Ugh. The labor cost, of course, is the bee-atch, more than the pump cost, of course.
