Back when I was driving a 72 Pinto as a DD, I was on the way to a morning appointment driving down the main street of a town when the engine suddenly stopped. Fortunately, there was an empty parking spot nearby so I wheeled in and popped the hood. It didn’t take long to notice that the timing belt had broken and was sticking out of the shroud.
I was dressed in suit and tie, but I had a few tools in the trunk so I took off my jacket, rolled up my sleeves and proceeded to take off the cover. I then walked several blocks to a Ford dealership and purchased a new belt (which fortunately they had in stock) walked back, lined up the pulleys and replaced the belt and cover.
I had phoned my appointment that I would be a bit late so I drove to a nearby service station where I cleaned up, put my jacket back on and drove to my destination. I was only about an hour late.
