Any special tool needed to remove the fan on my truck? Or just a large wrench? If so, what size is it, any idea?

06 4.0 sohc.

 

Fan clutch does have special tools for removal but many can do it if they have their own "special" tools.

On the rad support there will be a label that tells you which way the nut is turned to loosen and tighten, my 4.0l OHV(older) has regular threads, i.e. clockwise tightens, counter clockwise loosens.
Some engines use reverse threads because water pump pulley turns the other way.

The Ford wrenches are not too expensive, they are just flat wrenches, one grips 3 of the 4 bolts on the pulley, the other grips the fan clutch nut.
You can often rent a set of these tools for $10, some auto parts stores have loaners.
Post #2 here shows fan clutch wrench set: http://www.explorerforum.com/forums/...d.php?t=430429

You can used a thin crescent or open end wrench on the fan clutch nut, and a strap wrench(like used for oil filter) on the pulley, but it is hard to get a good grip on the pulley.

 

perfect thank you sir, Now I just have to find them somewhere. Im in Canada land.

 

Me too :)

All auto parts stores carry these, Canadian tire will as well.

But usually they only come as a set of 6 to 8 wrenches covering many sizes of fan clutches.
This is where you decide how many times you will need something like this, and then make the call to local tool rental place and get their price to rent the set for 24 hours.
Also call some auto parts stores and see if they sell these wrenches individually.

 

yeah, $70 for a set. I guess that's not too bad really, May just buy it.

 

You also need socket wrench to use most of these as well, although most have socket set already, just a heads up on that.

The fan will have slots/indents between the blades where the nut wrench fits in, this can be helpful :)

 

yep, lots of socket wrenches and breaker bars. I already have lots of specialty tools, just not this one yet! I do all my own work on my vehicles and most the work on my families so I've collected quite a few tools thus far. Just never had to pull a fan off before so I never had these ones yet!

 

and just my luck, the set I bought was missing half the tools. /facepalm

 

And I take it it was the half you needed

 

Of course! Why would it be any other way? Was the last one they had too, so I guess i'll have to order some.

 

just an update, So I never ended up getting the special tools needed. Decided instead to just try something that I came up with, and i'm sure plenty of other people have done before.

I took a strap from a ratchret strap. wrapped it around the water pump pulley and hooked it down into the frame. I then took my giant 36 mm wrench, slapped it on the nut and with all my strength managed to get the nut loose.

worked like a charm! came right off. no special tools needed.

To put it back on I just wrapped the strap around the pulley the opposite way and tightened her down.

 

Good work

Yes, strap wrench, leather belt or old serpentine belt works, have to be careful on some water pump pulleys, if made of thinner steel they can be warped/bent using strap wrench

 

thankfully mine was all good! tried using an oil filter wrench, but there was no way I was getting enough leverage on anything to hold it strong enough other than a strap hooked into the frame. That nut was on there TIGHT. 9 years and 260k kms had done a number on it, had never been removed before.
