So I’ve had some “belt squeal” for months, no big deal just get some dish soap, right? Turns out it wasn’t the belt, but the pulley, so now the belt isn’t tight enough to give power to the alternator. I was trying to limp it home, but it died on the highway, luckily on a downward grade so I could coast it in neutral onto the shoulder. I’m going to thank my Dad so much tomorrow for the AAA subscription, really handy to have in these situations.
