Yes it is a inteference engine. I just changed my timing belt last week. in the instrutions that came with the belt,waterpump and bearings . says this is a 1.6L interference motor. I had 50,000 miles on my aveo the belt look good what suprised me was the old belt said gates power grip daewoo made in korea. if these belts brake at 60,000 i am suprised gates has there name on it. I put a gates made in u.s.a. back on it.
