Water pump Hepu or Pierburg

Get a pierburg if you can for the water pump. They’re more OEM than Mehle is for water pumps even though both are OE manufacturers.

Graf & Hepu brand water pumps are both metal impeller high quality oem suppliers

I also used a kit from FCP Euro about 8 years ago and it included a HEPU water pump that worked fine for 7 years until I dismantled that car.

Pierberg all aluminium has been good in mine.

Been on my Pierburg full metal one a few years now, no complaints

I replaced mine with a pierburg one. after install it was fine till I hit a decent bump, which led to overheating limp mode (i stopped the car as soon as this happened).

I kind'a have some project and I need to use Pierburg CWA50, all I got in my country is this pump from benz (**A0005001986**), is it same model as Pierburg CWA50? Because the head pump is same but the connector is different (facing upwards). I tried to find specs from this model, the result is empty, can't find any clue about flow rate. I do have original code from Pierburg, which is **7.04933.56.0**, but can't find flow rate either.

I am dealing with a similar issue right now on my CJAA which I changed the timing belt in April this year. Leaking from same spot. Hepu waterpump.

when my original pump went bad, i went to Peirburg so that the plastic housing wouldnt crack. Pump lasted about 20,000 miles, bought another one from fcp euro for the lifetime warranty but this one lasted 20 mins before i got those same codes and overheated.

I've had 2 of these die in less than 1 year. Junk!
