Remove Fan Pulley on Chevrolet 4.3L Waterpump removal

When it is necessary to remove the clutch type fan on a Chevy 4.3L, it can be difficult to turn the large nut without holding the clutch from turning. If you do not have a special holding tool you may break loose the nut by using a small propane torch and a adjustable wrench and small hammer. Solution: Heat the outside of the nut with a small flame from a propane torch. Slowly turn the clutch several times while heating. Next, quickly grab the nut with the wrench and tap the handle, I belive, in the counter clockwise direction. It should break loose easily due to the slight expansion of the nut on the threaded shaft. I've used this method successfully many times. Obviously be aware of gasoline and battery vapors with a open flame. Duh! Hope it works for you

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 remove fan clutch on a 2002 blazer


They make a tool for doing this, but it can be done without it. Use a square bar of something similar to place on the bolts to the water pump, using a large cresent, hold the pulley from turning and turn the large nut the direction of travel (same way the pulley turns). It's easier with the belt on.
