@David09 - I like the fact that these belts last longer than regular belts, according to the article. There must be differences in cog belts, however, even those used as timing belts.
I had to change a timing belt on a Honda at only 65,000 miles. Apparently this is standard for the Japanese cars, but I would have preferred if I had not had to change it until 165,000 miles instead. At 65,000 miles, I will have to make that replacement at least twice during the life of the car.
