yea almost without a doubt fan clutch.. pretty easy to replace, make sure you leave the serpentine belt attached to the pulley, using a 12 or 10mm hand held wrench (i forget which) you need to take off the 4 bolts that attach it, when i was doing it my fan kept turning! so what i had to do was use a pipe to extend the wrench and hit it quickly with a hammer to serve as sort of an impact wrench, also had to take the top of the fan shroud off, that was easy though, i think 4 clips and maybe 2 screws... all in all should take u 30-45 minutes
