Just a belt or more?

Just purchased my first Tundra, it's a 2013 CrewMax Limited. I purchased of Facebook Marketplace so I anticipated having to do some stuff to it. The seller mentioned some belt squeal when cold, and it has done so as he mentioned. But today (day 3 of ownership) it continued beyond the warm up. It is quite damp outside and that may have something more to do with it. I have already ordered a new Continental belt and plan to install this weekend. Any thoughts on pullies going bad with just 113,000 miles?

 

You can possibly determine if the belt is the culprit by spraying water on the ribbed side of the belt as it spins. This only works if the squeal is at idle. If squeal temporarily disappears, then the belt is most likely the culprit. If no change in squeal, then it most likely is a bearing - idler or tensioner pulley, water pump, fan clutch, AC, or alternator. A less likely source is crank pulley seal. To test the bearings, remove the belt and rotate each pulley by hand. It should spin smoothly and have no fore/aft nor side-to-side play. From my experience some fore/aft play in the PS is normal - most of the PS in vehicles I’ve tested have some play, about 1mm. The water pump bearing can be tricky because the fan clutch attaches to it and it has it’s own bearing, although it is rare for a fan clutch bearing to go bad. You would have to separate them which can be an involved process.
