A. Drain approximately one gallon of coolant from

the radiator (into a clean container for reuse
later) using the drain valve located at the bottom
of the radiator, driver’s side.

B. Remove the upper radiator hose (note hose

orientation), tire iron, upper 1/4" hose and the
three screws securing the surge tank. Rotate
the surge tank out of the way.

C. Disconnect the radiator hose support clamp,

located on the underside of the fan shroud.
Remove the two top fasteners securing the fan
shroud. Do not remove the fan shroud at this
time.

D. Attach the supplied crows foot tool to a 1/2"

breaker bar and slide onto the hex of the fan.
Attach the crows foot with the larger opening to
a 1/2” drive ratchet. Slide onto the four screws
retaining the water pump pulley. Remove the
fan and shroud together. Do not allow the fan to
fall against the radiator.

E. V-10 only - Install the fan spacer onto the water

pump and tighten.

F. Using a 1/2" breaker bar on the vehicles spring

tensioner remove the accessory drive belt.

G. Remove the center balancer screw.

HARMONIC BALANCER AND CRANK PULLEY INSTALLATION

NOTE:

V-8 ONLY - This process can be done with the fan and fan shroud

in place providing your balancer puller is equipped with a 5" or

shorter forcing screw. Removing the fan and fan shroud will

allow eaiser access to the crank pulley and the front of the

engine.

NOTE:

With the fan properly installed, the fan, fan spacer and

water pump assembly will keep itself “tightened” on a

running engine due to its right handed threads.

NOTE:

If the center balancer screw rotates the engine and will

not unscrew. Remove the rubber inspection plug on the

left rear of the block to make the flexplate accessible.

Using an 18mm socket and ratchet, rotate the engine

until a flexplate nut is visible. Place a 14mm deep socket

and extension on the flexplate nut and rotate the engine

counterclockwise until the socket engages with the top of

the access hole. This will block the movement of the crank-

shaft allowing the bolt to be loosened. This operation

may require the assistance of another person.
