Water pump GMB or Hepu

New water pump - HEPU $30.00

I have their water pump on my Rx7, it's been A-Okay for over 3 years.

Hepu is OEM, never had any issues with one.

Excellent time to learn to do it yourself and buy a $65 water pump and timing belt kit. Dirty cheap for the miata. Just find a kit with a GMB water pump and a name brand belt.

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

The two timing belts I've done the water pump have been that design.

It was a while ago, but I think I used a HEPU pump when I did mine.

My original plastic impeller pump failed at 145k miles. I replaced with with a metal impeller pump (Hepu IIRC).

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.

I had a defective hepu pump that leaked also. Only had about 20k miles on it
