QuestionI recently found a small trace of water coming from the bottom of the water pump(seal).Im wondering the efficiency of just replacing the gasket or how to diagnose if it is the pump in whole.Can I also get a walk through of the pump replacement?I really appreciate your timely response and assistance on this issue!
AnswerDisconnect negative battery cable.
Drain cooling system (Refer to 7 - COOLING - STANDARD PROCEDURE).
Remove fan/viscous fan drive assembly from water pump (2)(Refer to 7 - COOLING/ENGINE/FAN DRIVE VISCOUS CLUTCH - REMOVAL). Do not attempt to remove fan/viscous fan drive assembly from vehicle at this time.
If water pump is being replaced, do not unbolt fan blade assembly from thermal viscous fan drive.
Remove two fan shroud-to-radiator screws. Disconnect the coolant overflow hose.
Remove upper fan shroud and fan blade/viscous fan drive assembly from vehicle.
After removing fan blade/viscous fan drive assembly, do not place thermal viscous fan drive in horizontal position. If stored horizontally, silicone fluid in viscous fan drive could drain into its bearing assembly and contaminate lubricant.

2 - WATER PUMP PULLEY
Remove accessory drive belt (1) (Refer to 7 - COOLING/ACCESSORY DRIVE/DRIVE BELTS - REMOVAL).
Remove lower radiator hose clamp and remove lower hose at water pump.
Remove seven water pump mounting bolts and one stud bolt.
CAUTION: Do not pry water pump at timing chain case/cover. The machined surfaces may be damaged resulting in leaks.
Remove water pump and gasket. Discard gasket
