The Engine Timing Chain helps to coordinate the opening and closing of numerous valves inside of your engine. This car part is an essential component in the combustion process of your vehicle.

Put very simply, an air-fuel mixture enters your engine's cylinders when the Engine Timing Chain opens the intake valves. The Engine Timing Chain then closes those intake valves in order to begin the essential combustion and compression processes. In the end, this air-fuel mixture turns into the energy needed to keep your vehicle driving efficiently on the road.

Because the Engine Timing Chain maintains such an integral process within the engine, damage is typically caused by general wear and tear over time. Sometimes, although the possibility is rare, a poorly functioning Engine Timing Chain can even lead to things like engine failure. An engine that's failed can be costly to fix and many times, irreparable. Keep your Nissan in good shape by getting a new Engine Timing Chain as soon as you notice any potential issues or concerns.

If the Engine Timing Chain on your Nissan stops working the way it's supposed to, you may experience other symptoms as well. Your engine may misfire. Your motor oil might become dirty due to metal shavings falling from the worn timing chain. And as the Engine Timing Chain slacks and weakens, you may hear rattling noises when driving on the road.

If you suspect that your Nissan's Engine Timing Chain is on its way out, get a replacement as soon as possible. This chain is critical when it comes to keeping your engine in great working order.
