Water Pump Recommendations

Recommended Posts

I am looking at proactive replacement of the water pump on my 2000 996 C2 Cab. The OEM impeller is plastic. I found this water pump with a metal impeller on-line. A metal impeller seems preferable to me.

Anyone have any recommendations/experience with these?

Thanks

The idea of a metal impeller in the water pump at first seems like a good idea, because sometimes the plastic ones can come "unglued" from the shft and freewheel, not moving coolant. However, there is a downside to using a metal impeller. When the bearings on a waterpump fail, the impeller often can wobble, cut into the the metal parts of the pump, and distribute metal particles thoughout the cooling system.. Many think it better to spread out soft plastic particles than hard metal particles in this way.

Just my $0.02 worth.

Stay with the OEM plstic style, they seem to casue few problems than the aftermarket units, and also seem to live longer...........
