Water pump Gates or Pierburg
I put a gates on my 2005 in August. No issues so far.
Pros: no issues so far
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.
Pros: more OEM
I got a metal impeller gates and I’ve been beating on it for five years or more without any hiccups.
Pros: no hiccups, metal impeller
Vehicle:
BMW
I used a gates water pump on mine and have had no issues
Pros: no issues
Vehicle:
Nissan Skyline
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).
Pros: fine after install
Cons: overheating limp mode
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.
Part number: A0005001986
During COVID, that water pump was on backorder from Ford so I used one from Gates. I guess Gates had a bad batch and 2 of their's failed in the span of less than a year.
Cons: bad batch, failed quickly
The only one to really avoid out of the 5 choices on Rockauto is the Gates, because of the cheap stamped impeller. Personally, I would not go with an aluminum pump body in this application, but that's just my opinion after working on vehicles for a living for 45+ years.
Cons: cheap stamped impeller
I used a Gates pump the first time and it leaked. I uninstalled it, cleaned everything up, regreased all the seals, and reinstalled it it... still leaked. Turns out the Gates water pumps for the ecodiesel are just garbage.
Cons: leaked repeatedly, poor quality
I have Gates start leaking within 10k of installation.
Cons: leaking, short lifespan
Mileage: 10000 km
