Hi guys, all of you have been very helpful in the past and I want to thank you all. My problem this time is that I think my clutch fan needs to be replaced... I have ordered the parts and a replacement fan. The question I have is:

Do I need any special tool to remove the fan and clutch fan? Thank you all once again for your time and help

Do a search, once you see how its done its incredibly easy. there is a hole in the back of the pulley hub and a groove in the housing. line them up, put a strong pin in there to hold position, put a cheater on your front Allen wrench and its off. My special tool was an allen wrench with the short arm ground down shorter, long arm taped to a long screwdriver. Now it takes longer to R&R the fan shroud than the clutch

Go to Home Depot or Lowe's and look in the hardware section for their small radius steel rods. I got one that was about 1/4 or 3/16 inch diameter. Take it back to your house and use a pair of Vise Grips to bend the end about 1/2 inch from the end. Use this end in the slot to keep the pulley from moving. This is the cheapest way to make this tool.

thank you guys.. listen.. I took a look under the hood this weekend because I been hearing this clicking and noise, which has been getting progressively louder of the last week. It looks like the fan blades have been striking one of the pulleys and have been ground and chipped to the point to where I need to replace the fan.. now I am not sure if the clutch fans is really bad or if I am having a problem with the pulley.. does any one know why this could be happening? What would cause the fan blade to hit the pulleys? only thing I can think of is the pulley has become lose over time but that does not make since with my logic... Has any one ever had this problem? Thank you which again for you all of your help and advise

Bad motor mounts?

bad motor mounts? That does not make sense, can you please elaborate? if the mounts are bad how can that cause the fan blades to hit the pulleys? Both the fan blades and pulleys are attached to the motor which is stationary.. I am confused..

MARINE_V, it's possible the fan blade is contacting the black distributor cover. If you fail to engage the vertical slot the cover protrudes forward and contacts the fan, or the retainer piece broke off due to old age and the cover is contacting the fan blade. If the motor mounts were bad it's likely the fan would be contacting the radiator shroud.
