A thread on Pelican forum indicated that the Water Pump replacement with the Black COMPOSITE material impeller is the preferred choice now
- over the metal impeller version.
Would you agree? Why/why not? Are the earlier problems with composite material becoming brittle a thing of the past?
My car is a 1993 325i E36, M50 engine sedan.
I'm 100% sure my water pump just failed and I need to start that repair project.
I'd appreciate a authoritative answer to this choice. Thanks.
