  1. 1 Remove the fan and clutch assembly from the fan's pulley. The assembly attaches to the pulley with several bolts on the circumference of the pulley. To remove the bolts, position an open-end wrench over each bolt and turn each bolt in a counterclockwise direction while grasping one of the fan's blades to prevent the fan from turning with the bolt.
  2. Step 2 Pull the fan and clutch assembly away from the engine, then lift the assembly out of the engine's compartment.
  3. Step 3 Remove the bolts which hold the fan to the clutch. The bolts are located on the back of the fan, and can be removed with a open-end wrench.
  4. Step 4 Place the fan and clutch assembly on a flat surface with the clutch facing up, then pull the clutch straight up to disengage it from the fan.

Fan clutch is noisy on my 2003 Chev Blazer. how do i replace it?


The fan clutch is bolted to the water pump with four bolts, and the fan itself bolts to the clutch with four bolts. The easiest is to unbolt the fan clutch from the water pump since the fan may not clear the shroud. Once the four bolts are removed from the water pump the fan should drop down, and you should be able to wiggle it up and out. If not then remove the shroud which should have two bolts on each side. Remove the fan from the clutch, bolt the new clutch on, and do the reverse of removal. Depending on accessories you may have to remove the upper radiator hose but normally you can wiggle the unit out. Do not remove the pulley since this will only add extra work and frustration.

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.

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
