    GRAF & HEPU are the metal impeller kings. However, the GRAF has a anti-noise/wear coating on the impeller, you decide? $47 + ship.

    I'm getting parts for a timing belt change. Which pump is better metal or plastic impeller? Which brand is better Graf or Hepu?? Also, Why are there 2 thermostats with different temp. settings? Should I keep standard temp setting or go down a few degrees? thanks.
