Where can you find a timing belt installation diagram?
Go to your auto parts store, (a good at that) and buy the shop manual for your car and yr. All the details will be in it with pictured diagrams, k.
The Hayes repair manual for the Mystique has good diagrams with step by step illustrated instructions for timing belt removal and installation. You can find them in most auto parts store and they run around $20.00. In my opinion, I believe the Hayes manuals for this particular make and model are better than the Chilton manuals.
