Default fan clutch removal

I am trying to remove the fan from the water pump pully an a 97 1500 5.2 L. The water pump pully doesn't have any bolts on the front of the pully to hold it from moving when trying to loosen the 36mm nut on the back of the fan. The water pump pully has 4 unthreaded holes. Is there a special tool for this or has anyone ran into this problem and how did you hold the pully?

haha, there is a tool, but everyone has their own way of doing this.

i will start by leaving the accessory belt on and putting a good wrench on the hub, hit the end of the wrench with a good hammer to try and loosen it. one of two things will happen: 1- the hub will loosen and everyone is happy, 2- the waterpump pulley will slip on the belt.

If the pulley slips on the belt you have some options. i normally replace the belt while im in there so i dont really care if i damage it. I take a good size prybar and, with the belt still on (for extra grip), wedge it against the pulley to prevent it from spinning. it will take quite a bit of force, but it will work. the key is the sharp strikes on the end of the wrench with a hammer.

if you feel like it, a bit of heat on the nut never hurts... just be careful.

I made my own tool out of two bolts and a 2x3 piece of wood. I'd take a pic, but I believe it's in a box with my stock clutch fan in storage, but you basically measure the distance between the two holes and then put them in the wood at the appropriate spacing.
I did this only after getting my knuckles bloodied up trying to get the damn thing off when I installed my e-fan.

i use a strap wrench around the water pump pulley and large wrench that fits the nut (dont remember the size), it takes a few tries, but dont have to worry about messing up the belt. its worked for me on several times. or if you have an air hammer you can "chisel" the nut on the fan it wont really hurt anything, maybe scar the nut some but no real damage

You could buy a spanner wrench or just work with what you have already.

You can make a homemade strap wrench with a strip of rubber (like an old serpentine belt) and the end of a ratchet strap that doesn't have the ratchet on it, then put the hook on the frame.

The more you turn the nut, the tighter the strap will get.

Put a wrench on the nut and hit it with a hammer, it usually takes a few tries but always works for me.

My idea worked on my dads truck but not on mine. I grabbed a piece of flat steel and a couple pieces of dowel then made a wrench for it. The steel/bolt deal is a good one if you don't have a welder.

I plan to replace water pump when I install the kegger. What is the distance between centers on this" Anyone know the distance across the two holes opposite each other? I have a few spanners, but don't know if they will fit or if I have to fab something like this.

Thanks.

You can use a flat piece of 1” x 1/8" flat stock with just one hole in the end for the bolt, The bar will rest on the fan nut for the other rest point, you will have room in there for a wrench as well. A nylon strap wrench or a rubber one will work on the pulley as well.
