Question about 2002 GMC Envoy
With the engine shut off I can grab the fan assembly and the whole thing is loose. The bolts holding the fan on are tight.
If the pulley is loose and the bolts are tight, chances are the water pump bearing has failed.

The tensioner pulley may be faulty. There should be a lot of tension on the pulley to keep the belt tight. If the tensioner can be moved easily, it should be replace.

Hi Cro,Seems to me as if you may have a problem with your water pump. If your vehicle is loosing coolant, that will confirm it. With the engine off and the key removed from the ignition open the hood and check for any looseness in the water pump by taking hold of the fan blades and shaking back and forth (If they're plastic be careful not to apply to much force, or you may break them!). If there is play you'll need a replacement pump!Best regards Johngee10
