Aerospace Components Electric Water Pump

To clear the pump housing, just slot the small hole in the alternator bracket
that is there for the tab in the tensioner. Slot the hole so that the tensioner rotates
clockwise as seen from the front and this will push the belt downward, away
from the pump housing. A 39" belt worked for my case with an AFM 150-amp
alternator and Autospecialties racing crank pulley.
