Have you ever touhgt that this belt is too thin? Here in Finland, we have lot of problem, how long this timing belt last. My last original timing belt has only 30 000 km and I lost 4 valves. The timing belt doen?t snap, it loose it?s thoots. Before that my timing belt last 18 000 km.
Now I changed that belt and but 1" belt in. We have in Finland custom made 1" belt, which have two adjustable camshaft pulleys , couple of extra parts, which you need to install this belt,

And if you change your belt allways change your waterpump, because you can?t take it off without taking out the timing belt.
I take off my balancer shaft belt, because of that 1" timing belt. It don?t fit anymore, because 1" belt take so much space.
