Water pump Gates or OEM BMW

153k miles on my original WP. Still going strong too.

Has 137,000 miles on it original water pump. Still good to be used but don’t know when she’ll crap out. Very impressed that I lasted this long.

Had gates on my 06. PITA to replace but never failed, good gasket, ok bearing.

I would STRONGLY recommend you to buy ONLY a BMW stamped WP. I learned my lesson the hard way and want to help you avoid my mistakes. The main thing that fails in electric water pumps is the electronics, and the ones not stamped with a BMW logo often have these issues.

We used to install gates pump and belt kits, but saw too many leaking water pumps well before they were due for another belt. Switched to aisin kits and haven't had a problem.

I went with Gates. My oem pump on my Mazda CX9 failed at 90k.... The bearing failed and the amount of bearing material in the housing was crazy.

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

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
