Water pump Gates or GRAF

I installed one on me 325i 12k miles ago, no issues so far, it was part of the FCP euro water pump kits

6 months and 4000km on mine. Only found out a while after Graf has a bad rep. But no problems with mine yet.

Update: it was the water pump. Got a new Gates water pump (screws and gasket included). Installed it, no sealant or anything. Works flawlessly. Not a drop anywhere.

When you do get a pump, buy the entire pump (front and back hemisphere) (like a GRAF brand). If this engine has been moving grit, the rear half of the water pump will be worn more open and not be able to move fluid efficiently.

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

Their water pump especially is garbage.

I use the aisin kit or oem honda. I’ve had the tensioners in the dayco kits fail, and the water pumps in the gates kits fail

Have had bad luck with graf metal impeller pumps, multiple failures over 2 different cars.

Mines literally the same story as yours. It’s leaking out the weephole after about a month, less than 1500kms install. Their warranty claim procedure looks as complicated as it can get too

It’s a garbage unit, mine started to weep out from the hole after less than 1500kms. Warranty claim seems extra complicated to deter people from using it too
