The water pump on my 90 E34 535i, 5spd, 128k miles is starting to leak. So, what is a good OEM brand for my car. I looked at the EMP Stewart "high performance" water pumps, but they don't make it for my car. I looked at what else is out there and I see several issues:
- mfrs - water pumps are made by an assortment of mfrs: APA, GMB, Hepu, Graf, Meyle, Laso and Seleri;
- price - ranging from up to . In contrast, genuine BMW range from 6 to 6 for a remanufactured!
- propeller material - some are made out of metal, composite (whatever that is) and plastic.
So, what do you people recommend? I'm guessing my original water pump had a metal propeller, want to stay far away from Chinese made ones and well, low price is always good, but I'll pay more for well built.
So, let me know what you think. Thanks
