Re: 2005 Grand Jeep Cherokee 4.7 L Fan clutch
I changed my water pump on my 05 GC 4.7...clutch nut loosens counterclockwise like normal..researched this cause I thought it may have reverse threaded, not the case. Don't remember wrench side..32mm? I soaked area with PBBlaster thinking corrosion would be a problem but not the case. I fitted an adjustable large crescent wrench and gave it a firm tap CCW and she loosened first try, not even having to hold the fan blades to keep from moving. If you need to stabilize the clutch, there are holes in the belt pulley where you can put an allen bolt through(a hex head won't clear outer rim) from the back and attach a length of chain from the driver's side of pulley to some area on the driver's suspension,etc. which will keep the clutch from turning. I had this all set up thinking I'd need it but, as above, happily surprised.
Edit..did you remove the water pump with clutch attached ??!
Hope this helps...
