Hi All
I'm having major problems removing a fan clutch from a 2000 Chevy Blazer so I can access and replace the water pump. I've been working for a day and a half, still no luck. I've tried strap wrenchs, and the guys at the major auto part stores can't seem to give me the right tools or advice.

How can I get this thing off?!?!

Here is a picture of the holding tool that you need.
It fits in the water pump access holes.
You need this or something similar to hold pulley while turning the fan clutch nut...(counter clock wise to remove)
Most parts stores I know of do not have this holding tool.
Snap -on would if you have a driver in your area..
You can call Snap -on and they'll inform you of dealers in your area.
I know that doesn't help you now tho.
Some guys have used a big ,very large channel lock to hold the pulley...if you have that give it a try.
Best if you can get someone to help you,one holding the channel lock and the other on the fan clutch.
What can usually work is if you can hold it secure, then put the wrench on the fan clutch nut and give the wrench a quick good whack with a RUBBER mallet to shock it and break it loose...

Sometimes you can put a wrench on the mounting bolts of the pulley and hold while giving the fan clutch nut a quick whack as explained earlier.
But coming off is one thing,putting on is another..because ,the mounting nut when holding and turning the F/C nut will be going towards tighten (disassembly) and will help hold in place,but when installing the nut will have a tendency to loosen...
Hope that makes sense and helps you
