Aluminum water pump pulley?

mdwhalen90 · 07-18-2021, 09:21 AM

Does anyone make an aluminum water pump pulley for e92 s65? Mine has cracked and id like to upgrade it so it doesn't happen again.

The OEM GT4 pump is aluminum. The rest on the market have a metal impeller.
The metal impeller version I have is the GRAF.

Also installed a graf one about 1000 miles ago. So far so good

Do you mean the external pulley, that the belt rides on, or the impeller inside the water pump?

Ah yes, he could mean the pulley on the outside that runs on the belts as it is very easy to crack also.

I'm also looking for that upgrade.

I dont think its advisable to put a metal pulley on the metal waterpump flange. Just stick to the oem composite, put a small amount of silver anti seize on the new one and it will come off fine in the future.

Yes I'm looking for the external pulley mounted to the water pump.

Correct I've looked all over the Internet there are plenty of options for the E46 but not so much the E92. Wasn't sure if anyone knew of any!

I think he meant the pulley not the pump itself. The pulley is plastic.

Edit-I see someone already straightened this point out. My bad.
