How do you change the timing belt on a 1994 Mazda B-2300?

I am working on this. It is not a good idea. If the belt broke, I was told the valves may have hit the pistons. If you are looking to replace a worn belt, go get it done at an auto shop. The belt needs a special tool, and adjustment. It takes 2 hours to replace the belt, and you need a wheel puller.
