Many experts urge replacing belts at specific recommended intervals to prevent your car from breaking down. Losing a belt today means big trouble for the engine because serpentine belts are used on most engines to turn the water pump, alternator, power steering pump and air conditioning compressor. The timing belt keeps the crankshaft and camshaft mechanically synchronized to maintain engine timing.
Why Do I Need This Service?
It’s not easy to know the true condition of a belt by its outward appearance because most belts fail from the inside out. Belts break down with heat, mileage and age. Every time a belt passes around a pulley, it bends. Flexing produces heat that causes the rubber to harden over time. In addition, if the belt is loose or slips, the wear process can be accelerated. When the timing belt breaks, most of the time means serious damage to the engine and expensive repairs. |
Typical Service
Most modern vehicles today are equipped with serpentine belts and self adjusting belt tensioners. Serpentine belts should still periodically be checked for signs of wear and for looseness. Most car manufacturers suggest replacing serpentine belts every 40,000 to 50,000 miles. Because of the severity of the damage it can cause, the replacement of the timing belt is the most important preventive maintenance service of your vehicle. Service intervals for the timing belt varies from manufacturer to manufacturer, though most of them fall between 60,000 to 100,000 miles. |
