Sell the truck. It's broken 
Belts are super easy to replace. Some YT videos while you work will help guide you. Not sure the mileage, but usually a good idea to replace the idler pulley and such while you are there too - at the very least, inspect them to make sure they are not the cause of your belt issues. Sometimes, those sprays can make it worse. Overall a fairly cheap fix to replace the majority of potential problems related to a squeaky belt.
Also a good idea to invest in a Haynes Manual. One quick read through and you'll be hooked.
