Fan clutch screws on to the water pump. You can loosen it with a big adjustable wrench (it is about 1 1/2" or 1 9/16" hex). Leave the bolts for the pulley in so you could wedge a screwdriver under a bolt head to keep the pulley from turning. Give the wrench a hard **** to loosen and it should turn off by hand. Right hand threads so you will be turning it counter clockwise to remove.

The headlights on the envoy are the easiest parts of the car to repair. You just pull the two tabs at the top of the headlights, screw out the bulb containers and you are good to go

Sounds like you may have disconnected the battery. Does the rough idle only happen when the defroster or A/C is on? If so clean your throttle body with throttle body cleaner with the battery disconnected. When finished, drive it for 5 or so miles with the defroster / AC off to let the computer relearn the settings. This will solve your problem.
