Water Pump Installation
Water pump is located on the front of the engine. A drive pulley is mounted on the pump hub, and the fan is attached to the pulley. The fan clutch, if used, mounts to the pulley with bolts through the flange. The fan mounts on the back side of the clutch with separate bolts or studs.
These instructions will help you replace the water pump and fan clutch... In most cases the water can be removed from the top.
Consult a service manual or make a drawing of the routing of any belts or hoses that must be removed or loosened to gain access to the water pump.
