Subject: timming belt repair.
Question: (99 mitsubishi eclipse, 2.0L, Rs)- how would i replace my timming belt? Where would we find a reliable belt?
Answer: My apologizes, but I do not answer "How do I install..." questions. Those are much too time consuming and it would probably not be thorough enough. The 2.0L Eclipse engines are very particular and the timing belt is not an easy install. If you want to risk it, get yourself a good service manual. You WILL destroy your engine if the timing belt is set wrong.

Not only is the procedure a sticky one, but you'll also want to have a top quality belt. I would recommend going to your local Mitsubishi dealership to purchase the belt.

If you do not decide to do the job yourself, be sure to have a qualified mechanic to do it.
Good luck!
