My stamped steel impeller water pump runs as cool as the previous cast impeller pump. Both kept the engine temperature at thermostat while stuck in traffic with the A/C running on hot days - and you can't ask anything more than that.
The original water pump out of my '67 was a stamped steel impeller right from Pontiac. I'd say that would mean that Pontiac was happy with the stamped impeller's performance.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
