Q--How do you find out whether an engine is free-wheeling or interference? I have seen you give the answer for specific engines quite often. I have a 2002 2.5-liter Subaru Impreza.
A--There are several sources for this information, but the one I find most convenient is the Timing Belt Replacement guide on the Web site hosted by the Gates Rubber Co. (www.gates.com). It not only lists makes, models, years and engines, it has a nice graphic explaining the difference between an interference and non-interference engine.
