My fan is loose, I have checked the belts and they are still good, not warped, cracked. Not quite sure what it could be a friend suggested it could be the bearings if that is the case how do I get my fan out? Thanks for your help.

If the fan is loose then it could be the fan clutch and/or the water pump. The latter is usually the cause and the shroud and belt and coolant have to come out. Then take out the water pump. Best to do this when the engine is cold so as not to get burned

Check for fan wobble by pushing on fan fins. If pulley moves with fan, then water pump bearings are bad. Will need water pump. You can get a loaner tool set for removing fan clutches at any parts store. Basically big thin wrenches. May need to use a hammer to impact the wrench to break it loose. Best to do with belt still on. May have to use a tool to hold the pulley in place such as a long pry bar. To remove fan clutch with fan, shroud will need to be removed as well.
