Water pump Gates or Hepu

I have a Gates part with a plastic impeller in my car now and it's been attached to that motor since late 2015 with no issues when it was in my e34 and isn't showing any issues now in my E30.

Hepu is OEM, never had any issues with one.

It's quality components from GermanAutoParts. Hepu WP, Conti belt, and NTN tensioner pulley, damper, and idler pulley.

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.

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.

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.

I bought a Gates water pump off Amazon thinking I could go with a name I trust. Impeller grenaded after 5 months and less than 6k driven.
