Serp. belt slipping

[90sabre]

Today while driving my 99 Ram I heard a noise which turned out to be my serp belt tension pulley. Upon examination the pulley is moving back and forth creating a loud clicking noise. What should I do about this? I appreciate any help on this matter.

After looking at it in the daylight it seems its my water pump, the pulley attached to the pump is actually whats moving and there is fluid leaking from the water pump.
Any tips on how to replace this? Am I gonna need any special tools for this?

The hardest thing on this is to remove the fan, which is connected to the waterpump. Other than that it's easy, also make sure your tensioner is ok at ths same time, a lot of these pumps fail because the tensioner gets stuck and kills the waterpump bearing. Also make sure that you put the right bolts back into the right waterpump hole. I seen people re-install the wrong bolts and kabooom. Because some of these bolt lead into water passages and stuff I also so 1 vehicle where the bolt went right though the front cover, also make sure that you put thread sealant on any bolt that goes into a water bypass/ coolant passage. good luck

Thanks for the info, i got the new waterpump in succesfully. I was looking at everything closely tonight after the install and i noticed the tension pulley does have slight movement in it, not enough to affect the other pulleys, but is this normal?
