I have a 1.6 E-TECH ll engine in an 05 Aveo. The Chevy dealership told me to have the timing belt inspected at 30k and replaced at 60k. They told me they have had some come in with a broken belt at 62k-76k and since it is an interference engine have had major engine damage. Seems the pistons run into the valves when it goes. I have several questions. Has anyone had a timing belt break? How many miles were on it when it went? How much does the dealer charge to replace the belt? I want to do it myself, but can't find a Haynes manual for it. Are there any publications that would tell about this?
Has anyone replaced it themselves? Thanks in advance!
