Interesting day. Was bringing our 06' F450 home from delivering Christmas Trres. No trailer. Noticed all of a sudden no power steering, brakes hard to push, and battery light on. I was really close to shop so limped it in. Right before I got back "check gauges" light came on and temperature gauge was pegged. Pulled in to nursery and serpentine belt was hanging out the bottom of engine and truck spewing coolant out of degas. Belt didn't brake, somehow came off pullies. Getting it towed on Monday. Hopefully didn't damage anything else. Truck is stock other than Bullet Proof EGR, 58v FICM, and Oil Cooler.
