Rusted bolts on clutch fan

I am having trouble getting the fan clutch off the water pump. The bolts are rusted and I cant bust them loose. I put wd40 on them and let it soak in for few hours and still no luck. Any other suggestions?

Place a screw driver between two bolts on the water pump side of the clutch fan. This will stop the fan from turning when you try to remove the bolts.Make sure to use the box end of your wrench so as to not round off the bolt heads

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 do i get fan clutch loose on 97 ford explorer to put water pump on


Below are the tools used to loosen the fan/clutch from the water pump. Similiar tools can be purchased at harborfreight.com or at some large auto parts stores. The large tool can be attached to a breaker bar. It is positioned over the four water pump pulley bolts while the wrench tool turns the fan nut. It's a bit awkward but works. Good Luck!

Im trying to remove the water pump from my bmw 316i 1996 but i cant get the fan off, hav removed the allan key bolts for the outer part of the fan but cant get the centre piece off to gain access to the...


To get the viscous clutch of the water pump you first need to remove the belt pulley and remove the water pump. Then put the impeller of the water pump in a vice and using a 32 spanner screw the viscous clutch off. Note that the bolt on the viscous clutch is of left hand thread so you have to unscrew the opposite way to a normal bolt.

Cant get the fan clutch nut off the front of the old water pump so the pump can be removed Have Cowl removed the fan loose and Two bolts removed from the Water pump pully and belt loose


Ok, it's best to have the fan belt ON all the way, that way it holds the pulley in place. Then, put your wrench on the nut, and tap the wrench with a hammer. This will break it loose, and then you can unscrew it the rest of the way. It works like an impact wrench.

Unable to remove fan from water pump


Remember, fan has a reverse thread. Righty-tightey, lefty-loosey does not apply. You need a clutch fan wrench. (available at your local auto parts store.)
