Water pump Gates or Pierburg

Pierberg all aluminium has been good in mine.

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

Pierburg ONLY for water pump, no other brand is good.

with water pumps on e9x’s it’s Pierburg or bust.

I went with a gates.

I only use gates kits on any HDI I work on. Out around 30 fitted to friends and family cars I had one water pump bearing fail after 4 months they changed it with no issues but as it was a home fit not garage no labour cost offered no other issues.

Did hear Gates did have a bad batch of 2.0 Blue HDI OEM water pumps with impellers coming loose

I also had the Gates pump leak within 6 months. The input shaft seal was leaking. Gates used to be a great brand but these pumps are garbage.

I’ve gone through about 3 water pumps all within 10-30k kilometres and each time it’s something leaking other than the gaskets. Either the freeze plug starts to leak or the actual water pump does. Luckily i bought it through napa and they’ve been giving me new ones under warranty but the job takes about 4 hours and each time i have to buy new coolant which is starting to get expensive. The cheapest OEM pump i’ve found from mopar was 1000cad which in itself is crazy because the napa/gates are about $170

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.

Good choice on going with Aisin. I had to redo the job on mine after 2 months when the shitty Gates water pump started pissing out the weep hole. Will never buy another Gates pump again.
