I was advised that when taking the fan off of the front of my motor the big bolt has to be removed by turning it counter clockwise (reverse thread). Putting a cresent wrench on it and hitting it with a hammer doesn't seem to break it free.
Any trick or is it a regular thread that needs to come of the normal way?

Motor mount bolts need to be totally removed. If you can get at the front pulley from underneath put a wood block on it and jack from there. Watch your fan at the shroud to make sure it don't bind up might have to remove the shroud or fan
The best way is to remove the fan shroud, the motor mounts bolts and jack the engine up by a piece of wood under the front pulley and a jack. as you are jacking,make sure nothing is hitting the fire wall at the distributor or other parts. You should now be able to access all of the pan bolts.
Check the rotation of the bolts. My 99 Suburban was reverse threaded. I messed with it for an hour trying the lefty loosie/ righty tighty normal thinking before realizing it was reverse threaded and I needed to turn them to the right to loosen them.
remove belt drain radiator remove fan shroud remove fan /pulley remove top hose on water pump and lower hose un bolt water pump remember mark bolts because lower longer need sealant due to they go into water jacket remove and clean around both water openings before setting in place hook up upper bypass hose easier to hook up before install--replace and rebolt everything
you need a special tool , a fan nut tool , it's like a 1-1/2 " ,actualy
a little smaller , i use a 1-1/2" wrench and smack it with a rubber
mallet , but there is a tool for it , i think checkers auto has a loan
-a-tool program , but to buy it is expensive , it is normal threaded
- counter clockwise is off . a special tool holds the 4 bolts on the
pulley and the other part of the tool fits on the big nut . sorry i
can't fix ya , cuz who has a 1-1/2" wrench or the special wrench in
there home arsinal .
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.
