CHECK SERPENTINE AND TIMING BELTS Serpentine and timing belts can spell disaster if they broke down in the middle of the road. The timing belt is responsible for controlling the rotation of the crankshaft and the camshaft. It also directs the opening and closing the valves located in the engine to allow a free flow of air in and out of the car. Basically, it coordinates most of the engine’s functions. Proper functioning of the timing belts dictates that the valves must open and close at the appropriate time. They have to also be in the right position to do this. If there is any breakage in the belt, it will cause the valves to have different opening times for each cylinder eventually causing deadly damage. A serpentine belt, on the other hand, is a single, continuous belt that powers key components including power steering, alternator, air conditioning, and water pump. With the introduction of the rubber technology, serpentine belts now last longer (between 50,000 and 100,000 miles). Continuous exposure to friction and heat causes the serpentine belt to wear out. When this happens, replacement should be done.
