My Protege has about 108,000kms on it, so I would like to be precautious and get the timing belt done early, while it's still intact and doesn't cost a fortune to fix if it were to break. Also, knowing how much money I would save by doing it myself...with only some reference to how-to videos and info on the Web... would you advise me doing so? Or should I leave the work up to an experienced and trusted mechanic? I am a Mazda and general car enthusiast, but I do not have much experience doing my own mechanical work on vehicles. However, I might become proficient at it, if I were to try and learn and gain experience from doing so.
