'05 Water Pump Replacement


Step 4: Once the fan is loose, remove the 4 bolts holding the shroud to the radiator with a a 11 mm socket.  There are 2 on each side, the lower ones are a pain but they can be reached from the top, I used a 1/4 inch socket drive to get to these.

Finish removing the fan and remove the fan and shroud and set aside.

NOTE:  DO NOT STORE THE FAN FLAT.  The fan MUST be stored VERTICAL.  It has to do with the thermal viscous fan drive so be careful and don't lay it on it side.

Step 5: Loosen the 4 13mm bolts holding the fan pulley to the water pump.  You are just breaking them free while there is belt tension.


If you do not have a diagram of the belt routing on your radiator, I would recommend now taking the time to take a picture, sketch it out or find it in your factory service manual.

Step 6: Using a 1/2 inch breaker bar, move the belt tensioner and remove the serpentine belt.


Step 7: Remove the idle pulley on the left side of the water pump.


Step 8: Place a drip pan under the engine by the water pump to catch any fluid coming out.

Remove the Top radiator hose from the thermostat by squeezing the clamp with a pair of channel locks.  Sears carries a 9 dollar tool for these which I have to say would have made things easier.  But a pair of channel locks will suffice.


Step 9: Remove the heater hose from the thermostat by the same method.
