T1N Sprinter Series - 09 - Serpentine Belt Removal and Pulley Check (for Anna)

A fellow T1N owner, "Anna," is experiencing a horrible squealing noise under the hood and wants to check the pulleys to see if any are faulty/broken. Lacking a little confidence because she hasn't done this herself before, I made a quick video giving some basic tips to hopefully help her out.
Partway into this video, I misspeak and call the 17mm socket a "60 point" socket. oops.
