How the Belt Breaks Down
The timing belt can suffer wear and tear caused by engine fluids that are corrosive, high temperatures of 500 degrees or higher, as well as other components that work, including plastic and metal that could scratch the belt. The timing belt can be worn out faster in the event that you utilize your vehicle to travel through difficult and dusty terrains or drive more often than others and also have a higher mileage on your Odometer. The belt may wear out faster when there are other problems within your engine that need to be examined and are causing the parts in the engine to operate slower or more quickly than they are supposed to.
The rubber of the timing belt could break, crack, or get damaged over time, rendering it inedible. It is recommended that it be replaced every 80,000 to 100,000 miles by a certified technician.
