How do you change the water pump on a TrailBlazer?

Answer by  prabhakarancit (10)

First thing's first drain the coolant, then remove the fan shroud- and remember to disconnect the connector for the fan clutch, remove the fan- be very careful not to hit the radiator with the clutch because it will put a hole in

Disconnect the battery and drain the coolant. Remove fan shroud,fan clutch and water pump pulley. Remove the water pump and apply RTV sealant on gaskets. Now install the water pump.
