How do you replace a timing belt on a 1994 ford escort 1.9L after the timing belt breaks?

It would be a good idea to get a Haynes repair manual at your local parts place for $20. It will pay for itself the first time you do anything. There are 27 steps to R and R the timing belt. btw your engine is a non-interference engine which means that when the belt breaks your engine doesn't get any damage. So get a manual and do it yourself.
