:bonk:Need to replace water pump on '06 with the 4.2L. Cannot separate the fan shaft from the water pump. Looks to be simple....should just unscrew? Is there something special you have to do to separate the water pump from the fan shaft? Can it be done without taking the shroud out and disassembling the fan clutch? There is enough room to remove the pump if I can just get the fan shaft loose. Any help would be greatly appreciated.
