At what mileage interval should the timing belt 2000 mitsubishi eclipse be changed?

i just bought the car from a private party and the seller was not from the U.S so he did not speak or understand english. Buying the car from him was hard enough but it was such a good price. so i cant find out if he changed the timing belt. the car has 76,000 miles. also is there a way to check to see if the timing belt was changed?

Every 60,000 miles. At 120,000 change the water pump, the tensioner and the timing belt pulleys. Don't forget to replace the balance belt and balance belt tension pulley, that's the one that will break first and take out the main timing belt.(4 cylinder only). It's hard to tell if the belts were changed. I'd only go to a factory trained mechanic for Mitsubishi repairs, other mechanics really screw them up bad.

A dealer can look up where the car was sold and check maintenance records, give it a try and have them check for open recalls while you're there.
