serpentine belt and hose replacements
When do you replace serpintine belt and radiator hoses on diesel engines? Last year I replaced all heater hoses & tank radiator hoses. Autos are generally 5 years.

Belt life is not all that predictable, so frequent inspection is a better strategy than trying to make a maintenance decision based on years in service (for many industries, operating hours tends to work better). I am just home from a motorcoach tour in which our year-old Prevost coach threw a serpentine belt at about 30,000 miles and had to be towed 200 miles to a service center for Volvo diesels. Upside of that one was riding in a 50-year old MCI, as the final solution of our tour company's efforts to find replacement coaches. We had three different replacements in a 18 hour period.
