  Q: How Do You Replace a Water Pump?

  A: Disconnect the negative battery cable and drain the cooling system. Remove the cooling fan, shroud, drivebelts, and pulley. For 3.6L engines, also remove the air filter and inlet housing. Detach the hoses from the water pump, replacing deteriorated hoses if necessary. Remove all accessory brackets and the bolts from the water pump. Compare the new pump to the old one and clean the engine and new pump mating surfaces. Apply RTV sealant to the gasket and pump. Carefully mate the gasket and pump and attach the pump to the engine. Reinstall all parts removed and refill the cooling system. Check the drivebelt tension and run the engine to check for leaks.

  Q: How Can You Check the Operation of a Water Pump?

  A: Squeeze the upper radiator hose to check for pressure surge. Check for coolant leaks from the weep or vent hole. Listen for a howling sound at the front of the engine and feel for shaft wear if the water pump pulley is rocked up and down. Don't mistake drivebelt slippage for bearing failure.
