Timing Belt Replacement

Timing Belt Replacement in Philadelphia, PA

The timing belt, or timing chain on some vehicles, is a belt that synchronizes the rotation of the engine’s crankshaft and camshaft with the opening and closing of your engine’s valves. Depending on applications, in instances it also drives the water pump. When the crankshaft turns, the timing belt turns the camshaft. The Camshaft operates the valves in the cylinder head, while the crankshaft allows the pistons to move up and down. Your vehicle’s engine operates in four phases: intake, compression, combustion, and exhaust. During the intake phase, intake valves open and exhaust valves close as fuel and air enter the cylinders. As the air and fuel is mixed, compressed, and ignited by spark plugs during the compression and combustion phases, the valves close. The remaining air and fuel is pushed out of the exhaust valve during the exhaust phase. The timing belt is responsible for synchronizing this process and for opening and closing valves during normal engine operation. A broken timing belt depending on engine configurations might create catastrophic damage and will be costly to repair and leave you stranded on the side of the road.
