Yep, definitely swapping to the electric fan because why not. There's a ton of play in the water pump so I'm thinking it was spraying everywhere as the shit went down, but didn't leak out much from the expansion tank.Quote:

lol holy shit, I thought the fan clutch would go before bending the water pump shaft
I think it was the water pump bearings that went first and ended up destroying the belt, not the other way around. That bit to the right is a needle roller that fell out of the front bearing when I removed it. Original BMW part and I believe only a few years old.

I’ve seen worse, but not many. I am convinced hanging that fan clutch off the water pump wears put the bearings a LOT faster than electric fan cars. In the last 15 years I have seen way more failures way more often on auto cars for this reason.
On my last 330 sedan I swapped the fan clutch to an electric fan (car was auto) and it was a noticeable improvement in acceleration. I’ve been told someone did a dyno run and the gain is around 7hp. My car never ran hot, even in the Alabama heat. I also deleted my aux fan to help airflow to the radiator. Hope that helps.
I agree 100% on the fan putting too much axial load on the bearings. I was reading that BMW went with the engine driven fan on the autos because it fails on (clutch locks) whereas the electric fan fails off and there is more overheat damage that can occur on the autos.
IDGAF tho I'm not putting this piece of shit back in there. Gonna cruise the local yards for a manual so I can snag that electric fan and toss the pusher too.
If you dont find one let me know, I’ll check my local yard for you. I know the owner so I can usually get smoking deals.Quote:
