Metal water pump pulley???

Does anybody make a replacment metal water pump pulley for the E38 to replace the failure prone plastic pulley?

Do you mean pully, or impeller? the pulley (the part the belt runs on) should already be metal, it's the impeller internal to the water pump (that actually moves the water) that is plastic.

And yes, there are a few available. Best one is from Graf. One great source that really supports the E38 community is oembimmerparts.com. That's where I got my water pump, and it's been great. Max there is a great asset to the community.

We use the Graf water pumps here at the shop.

Let me explain. The ribbed water pump pulley on my E38 is plastic and not metal. Does anybody make a metal replacement ribbed pulley?

Same place I linked you to in my previous post. My OEM pulley is metal, as far as I know. And it's original at 180k miles.

I've never heard of a pulley failing on any E38.
