Fan clutch removal?
 
All right got the wrench from oriellys but do I need something else? I know its a left hand thread but how do you keep the belt from turning?

Actually there are two wrenches required, one to hold the pulley and the other to remove the fan. If you only have 1 then try hitting it with a BFH, it should break loose.

Mine had right hand threads. In fact, on the fan shroud, there was a giant sticker indicating that fact. I took a 1-7/8" wrench and used a grinder to make it narrow enough to fit in there. Then, I clamped a pair of vise grips onto the lip of the water pump pulley to hold it in place.

Where does thebsecond wrench go?

onto the bolts that hold the pulley on.

I pretty sure it's left hand thread as viewed standing in front of the truck. Right hand thread if sitting in the cab. But it's been a few years ... :-X16

It's right hand thread (standard thread ) "Left hand thread" means you turn it to the left (counter clockwise) to tighten. But it is just regular thread, lefty loosy, righty tighty.

Got it off! Just didn't realize that I had the tool to put on the pulley bolts too. It was sloppy and I was afraid of stripping out the bolts but I guess that's how most of them are???? Anyways thanks for the help! My sticker is non-existent, but it is RHT.

The "handedness" of threads will not change based on the direction from which you view them.

Totally agree with that and you are RIGHT, BUT if you look the NUT standing in front of the truck it will turn counter clock wise and if you are sitting in the cab, the NUT turns clock wise, when it is loosening (spl?). :-X04

Right. Stick your right arm out with your thumb pointing towards yourself and your hand partially opened. When you rotate whatever fastener you happen to be working with the way your fingers are pointed, it will advance in the direction your thumb is pointed. If you turn your hand around, you will be rotating the opposite way, but the fastener will also be advancing the opposite way. That's what makes a "Right Hand" thread.

A "Left Hand" thread works the same way, except with your left hand. That's the whole purpose behind throwing the word "Hand" into the description of the thread type.

If you know whether the fastener in question utilizes right hand or left hand threads, all you have to do is use that hand and point its thumb in the direction you want the fastener to advance along the threads, and your fingers on that hand will point you out the way to turn the fastener.

Edit: It's like the "Right Hand Rule" for angular momentum, for anybody who has studied college physics.
