Thanks for telling me the size of that bolt, but I figured it out yesterday. I went to walmart and picked up a little metric set, and discovered that the 12mm fit nicely!
Got my fan clutch off!!
Got my electric fan installed!!
Got all the wiring done!!
BUT..... something is wrong.
Now, when I crank the truck, I get this nasty clickitty-grinding sound that I believe is coming from the pulley (that had the clutch bolted to it).
SO when I removed the fan clutch, I just took those bolts and put 'em right back into the pulley, tightened it up as good as I can, but it still has some wobble in it. I don't think there's enough thread left in the bolt to crank it down any farther... what did I do wrong?
Other than the pulley wobbleing and screaming, the truck does seem to run a bit rough... is that because the pulley may have been turned a half-inch or so in the process of removing that fan clutch?
Help! this is my daily driver!
