Fan clutch screws on to the water pump. You can loosen it with a big adjustable wrench (it is about 1 1/2" or 1 9/16" hex). Leave the bolts for the pulley in so you could wedge a screwdriver under a bolt head to keep the pulley from turning. Give the wrench a hard **** to loosen and it should turn off by hand. Right hand threads so you will be turning it counter clockwise to remove.

its easier to remove with the belts on..but to late for that....you will need to heat up the part that screws onto the pump then take a big screwdriver or small crowbar and wedge it behind the pulley...... the fan will turn off to the right ...reverse threads.....hopes this helps

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.

How to change a water pump?


You will need to remove the upper fan shroud, remove the fan clutch that is threaded onto the water pump it is easiest to get the tool for this or you can use a bar between two of the pulley bolts and use a cresent wrench on the big nut. After you remove the fan clutch there is the small hoses on the top of the water pump and the lower hose on the bottom of pump. Then there are only four bolts holding the pump to the motor. Reinstall in reverse order. Let me know if you need more help.
