Water pump OEM BMW or Hepu

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.

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.

Hepu--the bomb,99% reliability,MADE IN GERMANY.

Graf and Hepu make 12v metal impeller pumps, direct fit no mods.

Well made, but they ain't cheap. Here's the diagrams for the N54 setup: http://www.realoem.com/bmw/par...fg=35 The water pump itself is over $500.

i bought the dieselgeek timing belt kit which includes the Behr german Thermostat and Hepu water pump. he says that the stock OE style thermostat is better and the reman OE pump (which now uses metal impellors) is better than the hepu.

Yup that's how my Z3 once tried to kill me. Doing 90kph on the off ramp and the ol water pump decided to retire. In the process dousing my rear wheels in coolant.

This was a Hepu pump. With far less than 60k miles. I'm thinking the coolant had gotten too old. Can't figure why else the pump would wear so fast. Noise statrted after coolant change, am running an AC delete setup.
