My escort (99, 2.0, SOHC) died the other day, after hours checking it out I discovered that the timing belt was toast (missing a good dozen teeth) - this is a Zero tolerance engine but I check all the valves, and compression seemed good enough, so I figured a new belt was a cheap fix in the slim chance the engine was still good. After installing the belt the engine ran great. I did notice that the tensioner didn't really seem to be spring loaded anymore - I could tighten it with an Allen wrench and it seemed to stay tight but I could also loosen it and it would stick out of the way without using a drill bit to hold it. So - should I replace it? or is it ok? how much tension should be on it?
