Mine is new and it squeaks; cheap crap from China. So, I'll look around for a Gates or Goodyear or ?

Far as a bearing squeaking goes, a trick we used often was to take a spray bottle with water in it and squirt the belt with the engine running. If it stops squeaking, it is the belt. Otherwise, it may be a bearing and for that a mechanic's stethoscope is handy.

Sometimes noise from a bearing travels thru the block to make it difficult to tell exactly where a squeak is coming from - in spite of using the probe on the stethoscope. A trick Marc Haibeck also uses is to remove the probe and just use the rubber hose as a makeshift directional pickup to poke around the front of the engine. That sometimes works when results with the metal probe is ambiguous.

Hope this helps.
