Water pump GRAF or Hepu

I have a Graf and I haven't had any problems.

I have 27K miles on a Graf with no complaints.

I installed the aluminum pump (Graf) on the wife's Tiguan and it has worked great since. Have put 40K miles on the metal pump and no issues.

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

It has a hepu water pump

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

I purchase the all aluminum pump made by Graf from FCP euro, they have a lifetime warranty, free shipping and good prices. I removed the manifold to get to the water pump. I had a problem with the cheap thermostat that came with it. It caused my car to run hot.

Update. The replacement HEPU water pump is now leaking.. from the freeze plug…

Replacement HEPU water pump is now leaking… from the freeze plug.. gonna let it ride and try a different brand when I change the belt in 50K miles

I’ve now popped two water pumps. Each of them have sprung a leak from the freeze plug. I seat the pump and o-ring by hand then torque bolts to spec.. each time they’ve been good for about a month or so, then start leaking from the freeze plug.. both pumps have been made by HEPU.
