hey trying to get the engine fan off it won't budge does anyone know for sure if its left hand threads or regular thread.

 

This is from a third gen, but maybe it will be the same...

(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.

 

On those engines I normally wedge a pry-bar or large screw driver between the fan pulley and the timing cover to lock the engine down then use a hammer on the end of the wrench to knock it loose, it is reverse threaded and is very tight so it can take quite a bit to get it loose but once it break's loose it will spin right off, be careful tho, when it comes off it is kinda heavy and the fan will cut the daylights out of your fingers.

 

use an air chisel it works fine too or do as I did and bought the fan clutch tool for 37.00 I have 3 dodges so I need it

 

The barring tool for pre-duramax HMMMV fans will work also if that venue is more accessable for you.

 

It's left hand thread. You will want to "drive it" or turn it toward the drivers side to remove.

 

fschiola: I could be wrong but I think you meant right hand if it loosens toward the drivers side.

 

No, it is definitely left hand thread, and you rotate it to the driver's side to remove it. (righty-loosey, lefty-tighty)

On the common-rail engine they went to a right hand thread because the fan pulley runs off of the backside of the belt.

 

LoL! I get so confused!

 

To take it off always turn it direction of fan rotation. You'll never go wrong that way.
