I needed the water pump replaced on my truck, 1994 ford ranger splash 4.0, I cant seem to break the nut loose holding the clutch on. I know its left handed threads but just to make sure Im doing this right, standing in front of the engine I need to turn this nut to the right, correct?
Ive tried the nut removal tool, it bent making a nice little rounded off edge on my nut. :temper: I cant seem to get a crescent wrench, or any other wrench down in there just not enough clearance. Anyone have any other ideas on how to get the danged ol nut off?
Any and all help would be greatly appreciated.

Thanks
D. Carey

You need to turn the clutch nut to the left if you are standing in front of the engine. If you turn it to the right, that is right handed threads.

well dont i feel like a ding-ding. If every other nut, bolt Im taking off is turning to the left, and Im told the threads on this thing are reversed, I try to turn it to the right, no wonder my tool broke, grrrrrrrr.
OK well I reckon I go get a new one and try it again.

I don't know so much bout left and right...But clockwise is the correct turning for a "left handed" nut.. Anti clockwise is regular.

If I remember corectly the motors that have regular v-belts have clutch fans with left hand threads as they are driven from the inside of the belt and consequently turn the same way as the motor. The motors with multi-v or serpentine belts have right hand or normal threads as they are driven by the outside of the belt and turn in the opposite direction to the motor. It's usually marked on the top of the fan shroud. If it is actually left hand thread it needs to turn clockwise to remove, as viewed from the fromt of the truck. I usually use a pipe wrench.

Remove waterpump from engine with fan attached and put pulley in vise. Protect it with some wood slabs and only tighten it enough to hold it securely - you don't want to crush it to an egg shape. Use the wrench and a hammer to shock the fan loose.

Finally got the danged thing off. The haynes manual said it was reverse threads so I did what any idiot would do, I turned opposite direction to take off, nope, uh uh, no way, WRONG. I took the pump off with the fan clutch attached, not enough room in between the bolts that hold the pulley on and the fan to get anything that doesnt belong down in there. Took the bolts off, slid a pipe wrench in there and held the fin off the pump with a big ass pipe wrench, twisted the fin right off. Ended up putting two bolts back in pulley to hold it, slid in crescent wrench and used my big ass pipe wrench to hold pulley and off she came, to the left, not the right as the book suggested.
Thanks for everyones input.

The last one I did, I took the pump/clutch/fan out in one piece. Then welded the impeller to the housing before using a large vise and the "spanner" with a length of pipe to break it free.

easiest way i coud do it was a solid steel rod pointed at one end and flat on the other and a big hammer, took the pointed end a hammered a dimple in the nut, then went on an angle and hammered the nut in the left direction and it came off first try every time that ive tried it

clutch fan removal

I replaced the clutch fan on my 92 4.0 tonight. After getting severely frustrated and wasting nearly 2 hours I came to the forum. The long steel rod worked perfectly. I really had to hit it, but it came loose. I found rusted indentions where someone had tried it once before.

Water pump

The first time I replaced my water pump I had pretty much the same experience. After getting it off, I sat the new pump up on the radiator before I put it in place. At that point I noticed an arrow formed in the plastic of the fan shroud that says, "Fan removal direction" or words to that effect. :bawling:
