The second groove is not used. Additionally, the A/C bearings should be changed if they have not been. The DeLorean water pump has one belt grove. The belt and pulley bearing kit is included in any of the DeLorean vendors tune up kits. In addition, make sure that the belts are correctly installed on the crankshaft pulley.
