Fan clutch removal without tools?

Has anyone here been able to do this without that skinny 35mm wrench and nut holders?

You can probably do it with a standard (not skinny) 32mm wrench and no counter-holder, if you're resourceful and lucky.

Without that wrench, though, it's close to impossible. MAAAAYYYBE a crescent wrench might work?

Super simple just use an airhammer with a long blunt bit. Hit the edge of a corner on the fan nut. just takes a tap to break it loose, then spin it off by hand. Remember its left-hand threaded!!

I was able to remove mine with a standard Craftsman 32mm wrench without the pulley holder.
It had been removed once before by the dealer about 3 years ago, that may have helped.

I also was able to just use the 32 mm Craftsman wrench to loosen it and it unthreaded off pretty easily.

I had the W/P bolt holding tool also but couldn't get the correct angle to use it. Anyways, if the clutch has been taken off before then you probably can just
get by using the 32 mm wrench.

I took mine off with Channel Locks. The nut is not supposed to be _really_ tight. It is a Reverse Thread that is made tight by the rotation of the engine instead of being made loose.

You might have to use a screwdriver (a very long one) wedged across two of the four screws that hold the pulley onto the front of the water pump to stop the pulley from turning while you turn the nut on the fan clutch. The torque on the nut is measured in inch pounds, or very low foot pounds.

The torque spec for it is 40Nm or 29.5 FtLbs (354 InLbs) That really isnt that tight, if you can stop the pulley from turning it should be fairly simple to loosen it unless someone has cranked it down super tight before.
