The timing belt is responsible for transferring the rotation power produced by the crankshaft to the camshaft, which in turn causes the valves to move, providing fuel and air to the cylinders, as well as expelling exhaust fumes. If the timing belt is not performing its function as it should, perhaps because it is stretched or damaged, this process does not happen in the precise synchronized fashion that it must to produce efficient engine performance. In this situation, your vehicle could develop such as rough idling and acceleration, excessive exhaust emissions, loss of engine power, backfiring and poor fuel efficiency. For this reason, it is critical to be sure that your vehicle is equipped with a quality timing belt, such as the Dayco timing belt. Dayco has been a leader in innovation and design since its founding in 1905, and has built a sterling reputation for quality in every product it makes, including the Dayco timing belt. If a poorly operating timing belt is not replaced promptly, chances are that it will break leaving the vehicle at a standstill and the driver stranded. That is all that happens with most engines, but if your vehicle has an interference engine, there can be expensive engine damage as a result of a broken timing belt. A quality Dayco timing belt can help avoid such problems, as it reliably does its job, keeping your vehicle running as it should.
