as far as why you need a new water pump its becuase with a serpentine belt setup, the water pump spins the opposite direction... the water pumps are sometimes called reverse rotation pumps..

Oh yea, I was scared for a moment. The picture was taken during motor installation. I changed it when everything was buttoned up. I wondered why the stock belt was too short.
