Water Pump Pulley on 2003 Jeep Liberty

How do you tighten the pulley on the water pump? The water pump pulley is loose and this caused my belt to come off track...

You may have a worn out water pump that is causing the pulley to wobble, which is VERY common on Jeeps. You can check this by grabbing the water pump pulley and seeing if there is any play or movement. There should be none at all. Of course, do this with the Engine OFF!
