Why did my new water pump broke again? :$

[oleh]

Its for Bmw 535I with m30 3.5l engine

I just got my water pump replaced 4000 miles ago. Now its leaking from the same spot on the midle around the shaft.

I just wana find out why it broke again?

When i wiggle my fan it feels loose could it be why? or maybe the mechanic put to much tension on the belt?

how did you last one break? mine was loose in the shaft, making the fan be able to wiggle, so i replaced it, havent had a problem yet

it broke the same way you explained it, it got loose in the shaft. And now there is a new one and a same thing happened.

Some units are inferior to others.....I had this happen to me with a Geba (IIRC) pump at 5k miles.

A shitty pattern part instead of OEM, maybe? I went through two "bargain" clutch slave cylinders in less than six months in my E28 until I wised up and bought one from BMW. The price was twice as much, but half the weight and four times the quality, and I haven't had to replace it since.

gotta a blade missing from the engine driven cooling fan ?

Im not sure what brand, but i know it was an aftermarket forsure.
