Fan tool (special tool for fan removal)

After running into problems with the pulley moving while trying to break free the fan nut on a '97 S-10, I ventured up to Advance Auto. I was looking for a large wrench to fit the nut, & they lend tools for free. I told them that I was trying to remove the fan & they informed me of a tool especially made for this purpose. They had a whole kit. There's a large wrench that fits over the pulley bolts to hold it in place so the nut wrench can break free & turn the fan nut. This thing was easy as pie to use, & the fan came right off. and the best part is I'll get my money back on the tool when I return it. Many thanks to the ones that gave suggestions, & special thanks to Concrete who already suceeded with these mods. I'll try to attach a few pix. I've already seen close to a 3mpg increase with just a 10psi change in my tires. That's put me at the 30mpg. I'm really anxious to see what this fan removal, & grill block is going to add. I did the grill block with an old house for sale plastic sign covered in duct tape. Walmart has just about any color duct tape you want to buy for $3 & some change. I picked up the chrome & black.

Shoot, can't show the pix yet. The files are too big. I'll have to load them on my desktop where I have PhotoShop to shrink 'em down some, then attach them for all to see.

Here's the pix of that fan tool kit & how I used it on the fan pulley. Plus the chrome duct tape grill block.

Gasgauge,

Congratulations on the fan mod
glad you did not need to use a sawzall like I did
who would have thought there was a special tool kit for a fan removal!

I think you will enjoy this mod
quicker warm ups with economy & performance to boot
not the same as installing a 350
- but I think you will notice a bit quicker revs without that paddle wheel installed

I'm interested to see your gains too!

Good Work,

Argghhhhhh, the truck got hot on me today! Temp guage was reading between 180-185, must be incorrect. Off came the grill block & new order for a scan gauge this aftn. I thought this radiator was big enough for the 2.2 minus fan during the winter. I already took that fan tool back too. guess I'll be investing in a Efan sooner then I thought. Last thing I need to do is burn up that mtr with 87K on the clock. and hear my wife say, I TOLD YOU SO, I TOLD YOU SO......

LOL - I pulled the fan off my friend's lowered S-10 with a screwdriver between the bolts to hold the pulley in place... the only reason I needed to use a screwdriver was because he had already taken the fan belt off... you can use a piece of string and a 1/2" drive socket wrench to lock the pulley in place w/ the belt on.

Use the wrench to loosen the tensioner, wrap the fan's belt around the pulley to make max contact and tie it to itself w/ the string. Slowly let the tensioner go, and you won't be able to turn the fan pulley anymore.

You should be able to use an e-fan from most FWD Chevy models... the radiators are all close to the same size, but you may have to strap it on with something instead of bolting it to the correct locations on the fan shrouds.

If your ever going to use the A/C in the summer make sure you get a fan that flows 2200cfms. If you spring for one of those perma-cools at autozone your still going to overheat in the summer months.
