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 am getting a P1481 code, From what I see it could be the Fan Clutch, but would it also cause it to shift at a higher RPMs, It only does it some time.


OK, loss of cooling fan speed. I will say this is plausible. I'll take your word for it (sometimes my online resource is not complete).

Water pump replacement


Disconnect the negative battery cable, then drain the engine cooling system. 2. Relieve the belt tension, then remove the drive belt. 3. Remove the upper fan shroud, then remove the fan or fan and clutch assembly, as applicable. 4. Remove the water pump pulley. 5. If applicable, loosen the clamp(s) and disconnect the coolant hose(s) from the water pump. 6. Unfasten the retainers, then remove the water pump from the engine. Note the positions of all retainers as some engines will utilize different length fasteners in different locations and/or bolts and studs in different locations. To install: 7. Using a putty knife, carefully clean the gasket mounting surfaces. 8. Apply 1052080 or an equivalent sealant to the threads of the water pump retainers. Install the water pump to the engine using a new gasket, then thread the retainers in order to hold it in position. 9. Tighten the water pump retainers to specification: For the 4.3L engine, tighten the bolts and studs to 30 ft. lbs. (41 Nm). 10. If removed, connect the coolant hose(s) and secure using the retaining clamp(s). 11. Install the water pump pulley, then install the fan or fan and clutch assembly. 12. Position the serpentine belt over the pulleys, then carefully allow the tensioner back into contact with the belt. 13. Install the upper fan shroud, then connect the negative battery cable. 14. Properly refill the engine cooling system, then run the engine and check for leaks.

I need instructions to install a clutch fan on 1987 bmw


The fan/clutch assy has left hand thread. Loosen by turning clockwise.

Remove radiator top shroud & air cleaner assy. to gain access.
Remove engine cooling fan by holding the belt drive pulley with a suitable flat bar tool (that fits over the top of the drive pulley attachment bolts), then using a suitable flat spanner to unscrew the fan clutch assy (clockwise). When re-fitting, tighten clutch nut to 30 ftlb.
You may need to use a bit of ingenuity in making the flat bar holding tool, unless you are able to procure the BMW tool #11.5.030.
Good luck
