The thing you will have the most chance of screwing up is installing the balance belt. Before removing the timing belt you should have all the crankshaft and cam gear timing marks lined up. This does not guarantee that the balance shaft is aligned. Once you have the old balance belt off, you need to spin the small gear on the right side. It has an arrow and notch in the gear that line up at the 11 o'clock position. When you spin the gear by hand it should self center toward the 11 o'clock position, not at the 5 or 7 o'clock positions. Just spin it clockwise until it centers at 11o'clock. It's the one thing mechanics not familiar with Mitsubishi's miss and it gives you a real shaky idle and low rpm.

If you have over 70,000 miles on the motor, replace the water pump and all the pulleys including the balance belt tension pulley.
