Ferrari recommends that you replace your belts every 15,000 miles or every three years to insure that they do not become brittle, causing them to break, which could result in serious engine damage. This Testarossa had never had a belt service in its entire 27 years of existence. (keep in mind that it did sit without use for many years becasue of this) The belts were so brittle that Craig was able to break the main belt apart with his hands. The entire engine assembly must be removed to perform this service. The removed engine is shown with the old belts removed, and the new ones installed. The last three photos show the cleaned up and finished product. The following video shows Craig breaking the belt.
