It is regular threads. You need to use a strap wrench to hold the pulley. Or make one by using a old leather belt. Just wrap the belt around the pulley. Put one end through the belt loop in the opposite direction.

How do i remove the fan and pulley on a 1987 ford ranger 2.9 v-6?


The question is: How remove clutch in order to remove fan mounted on its engine-side face.
  • Generally, the clutch drive half shaft must be uncoupled from coolant pump (impeller drive) half shaft using special wrench kit available as loaner from AutoZone (free with $79 approx deposit).
  • Best done after shroud & radiator remove after coolant drained.
  1. Uncouple coolant pump and fan clutch drive shaft(s) as follows:
    1. span across combo-pulley-sheaves-unit mounting bolt heads with large tool kit wrench, and
    2. span inline clutch coupling nut with small tool kit wrench. Then,
    3. turn small wrench (and coupling nut) CW while resisting with large wrench (CCW) to turn coupling nut until disengaged from coolant pump drive shaft.
  2. Remove fan/clutch assembly.
  3. Note direction of mounted fan hub and fan blades orientation to ensure proper re-assembly.
  4. On rear of clutch assy, remove 4 bolts to disengage and remove fan.
  5. Assemble new fan to clutch (or, preferably, new clutch and new fan) using new bolts and washers provided with fan.
  6. Couple fan-clutch assy to coolant pump drive shaft as per opposite of uncoupling step 1, above. (Turn inline nut CCW to tighten...30 ft-lb.
  7. Check that fan can be hand turned...CW.)
  8. Rest shroud over and onto fan.
  9. Replace radiator; remount shroud; reclamp hoses, and refill and air purge cooling system.

I'M wondering if I should bolt the pully back on and hold it with a strap wrench, then turn that big coupling nut off.I allready have belt off.


If you're referring to removing the fan/fan clutch. Put the bolts in the pulley back in, put the belt back on. Get a long chisel and give the nut one good shot with a hammer. (it's reverse thread) And then spin it off.

I am replacing a water pump on a 1999 dodge durango, 318 ci, 5.2 litre engine. i am already encountering problems, i started removing the water pump assembly, removed all the bolts, the whole things is...


ur supposed to unscrew the fan at that big nut and remave the cooling fan shroud first then youll have all kinds of room. snug the pump back to the motor and break that nut loose. i always use an air hammer and chisel in the left of the top flat on the nuts, it starts it in the right direction and then un threads easy. you have to hold the pump pulley and turn that big *** nut. you can borrow tools from parts store for it if you dont have anything

Removing the cooling fan & fan clutch assembly on a 4cyl. engine.


Ok...the main nut that you arre tring to take off to seperate the two..It is reverse tread....so you have to go the opposite way to take it off. You may also need to go and buy this tool...

Fan removell


The big nut is part of the fan it threads on to the water pump. To remove loosen two of the pulley bolts put a pry bar between these two bolts the use a large wrench on the big nut to thread the fan off the pump. righty tighty, lefty loosey. They also make tools for removing the fan clutch.

The big nut spins counter clock wise. you have to put your pulley bolts back on and make sure they are tight. leave belt on so that you have more resistance to pull against when tring to loosen the nut put a bar inbetween the pulley bolts so it won't slip off and then loosen that big nut looking thing and you should have it from there. to the same thing in reverse order to install it
