Well I just hit the big 100k on my 2000LC with no major problems (knock on wood) and am bringing the truck in for service. I am getting mixed messages about what to do and need some advice. Obviously, I am doing the timing belt, seals, water pump & S- Belt at the same time, but two different dealers have told me they have not seen failures on the tensioners or idler pulleys. Question is has anyone had failures & when? Can it wait till 200K?
