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.
2. 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 en-
gine.
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 en-
gages with the top of the access hole.
This will block the movement of the
crankshaft allowing the bolt to be loos-
ened. This operation may require the
assistance of another person.
