: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.

search threads...."fan clutch removal".....tons of good info there...you need a BFW.....big f'n wrench to remove the nut from the front of the water pump....there is a special tool made, but look at the pics posted and the write ups by the hundreds of people that did their change....i did mine, took about 2 hours and yes, the fan shroud has to come out......good luck...
