Wife's PT Cruiser snapped a timing belt

For some good advice on this subject may I suggest you go to www.ptcruiserlinks.com. Everything I've read there says that the engine is a non interference engine. They say that when the timing belt is changed that you should also change the tension-er and water pump. And also it is said that this belt is a real pain to install correctly and often suggest that unless you are a very skilled mechanic, it might be best to have it done in a shop.
