First time as member to site. Thanks for the help with the simple fuel filter change. Has anyone ever changed the fan clutch on a 2003 Dodge Ram 3500 diesel. The part for what I can find is only around $70.00, but $400.00 in labor. WOW Any step by steps on this is appreicated

Hey Madhat, if you come up with anything that would be great.The part is only #70.00 but they want $ 260.00 to install. I am mechanically inclined so I dont think I will have a problem, but step by step will make it easier. Thanks for your effert. Doggyman

I have removed my fan clutch and hub along with the hole carrier to replace the baring for my 05. What do you need to know. It was not that hard really.

doggyman

Curious as to how indepth it is to replace fan clutch. Any steps by steps?

LeviMXUSMC

Not to in depth. first thing I did is remove the shroud. I got a cheap fan Clutch removel tool from Advanced that did not work due to being made of cheap metal. You can rent a good fan hub removel tool from just about any parts store..... let me see if I can find the step by step I found last year. Are you just trying to replace the clutch?????

doggyman

yes. All that is bad or failing is the fan clutch. When I took it in to shop I had to remove the hypertech setting and it showed DTC P0483 which is the cooling fan speed and the shop said it was ok now but when I start towing my 5th wheel I should do it. But the part is like $ 70.00 and they want almost $260.. TO DO THE JOB. sURE WITH STEP BY STEP i CAN DO IT, tHANKS FOR THE TIME.dOGGY MAN

RADIATOR FAN - 5.9L DIESEL
REMOVAL
CAUTION: If the electronically controlled viscous
fan drive is replaced because of mechanical damage,
the cooling fan blades should also be
inspected. Inspect for fatigue cracks, or chipped
blades that could have resulted from excessive
vibration. Replace fan blade assembly if any of
these conditions are found. Also inspect wiring harness
and connectors for damage.
(1) Disconnect the battery negative cables.
(2) Remove coolant recovery container (Refer to 7 -
COOLING/ENGINE/COOLANT RECOVERY CONTAINER
- REMOVAL).
(3) Using a fastener removal tool, remove the two
push pin fasteners from the fan shroud lower half.
(4) Unseat the four fastening tabs and remove the
lower radiator shroud.
(5) Disconnect electrical connector.
(6) Remove the electronically controlled viscous fan
drive electrical wire from the upper radiator shroud.
(7) Using a fastener removal tool, remove the wiring
harness bracket from the upper radiator shroud.
CAUTION: Do not remove the fan pulley bolts. This
pulley is under spring tension.
(8) The electronically controlled viscous fan drive/
fan blade assembly is attached (threaded) to the fan
pulley shaft (Fig. 4). Remove the fan blade/fan drive
assembly from fan pulley by turning the mounting
nut counterclockwise (as viewed from front). Threads
on the viscous fan drive are RIGHT-HAND. A 36
MM Fan Wrench can be used. Place a bar or screwdriver
between the fan pulley bolts to prevent pulley
from rotating.
(9) Remove the upper radiator shroud mounting
bolts.
(10) Remove the fan shroud and the fan blade/viscous
drive as an assembly from vehicle.
CAUTION: The electronically controlled viscous fan
drive is vibration and impact sensitive, especially at
the electrical connectors. Do not drop the unit.
(11) Remove the six fan blade-to-viscous fan drive
mounting bolts.
(12) Inspect the fan for cracked, chipped or damaged
fan blades.
CLEANING
Clean the fan blades using a mild soap and water.
Do not use an abrasive to clean the blades.
INSPECTION
WARNING: DO NOT ATTEMPT TO BEND OR
STRAIGHTEN FAN BLADES IF FAN IS NOT WITHIN
SPECIFICATIONS.
CAUTION: If fan blade assembly is replaced
because of mechanical damage, water pump and
viscous fan drive should also be inspected. These
components could have been damaged due to
excessive vibration.
INSTALLATION
(1) Install fan blade assembly to electrically controlled
viscous fan drive. Tighten mounting bolts to
24 N·m (18 ft. lbs.) torque.
(2) Position the fan blade/viscous fan drive to the
vehicle as an assembly.
(3) Install the viscous fan drive assembly onto fan
pulley hub shaft (Fig. 4). Tighten mounting nut to
115 N·m (85 ft. lbs.) torque.
(4) Install upper fan shroud. Make sure the upper
shroud locks into the tabs on the lower radiator.
(5) Install two upper shroud mounting bolts.
Tighten to 11.8 N·m (105 in. lbs.) torque.
(6) Position the electronically controlled viscous
fan drive wiring into the channel in the upper fan
shroud (Fig. 5). Make sure the wiring is not pinched.
(7) Install the lower fan shroud into position and
verify the two locking tabs have seated.
(8) Install two push pin fasteners to lock lower fan
shroud to the main assembly.
NOTE: Verify that the fan drive electrical wire does
not interfere with fan blade travel when the fan
blade is spun by hand.
(9) Connect the wiring harness connector and
install the harness bracket to the upper radiator
shroud.
(10) Install the coolant recovery container (Refer to
7 - COOLING/ENGINE/COOLANT RECOVERY
CONTAINER - INSTALLATION).
(11) Connect the battery negative cables.
NOTE:
Viscous Fan Drive Fluid Pump Out Requirement:
After installing a new viscous fan drive, bring the
engine speed up to approximately 2000 rpm and
hold for approximately two minutes. This will
ensure proper fluid distribution within the drive.
