Essential Auto Part: Chain Tensioner Assembly

To keep your vehicle running at its optimum efficiency, it's imperative to maintain perfect condition of the internal combustion engine. One integral part of this engine that often goes unnoticed is the Chain Tensioner Assembly.

Why Do You Need a Chain Tensioner Assembly

The chain tensioner assembly is designed to apply the appropriate tension to the timing chain connecting the engine's crankshaft and camshaft. Precisely timed coordination between these two parts is crucial to keep the engine's valves opening and closing at the right times during each cylinder's intake and exhaust strokes.

How Does a Chain Tensioner Assembly Work

The chain tensioner assembly ensures optimal tension at all times, compensating for variations during operation. It uses a spring and a hydraulic piston to apply a specific amount of force to the timing chain. This extended force prevents the timing chain from becoming too tight or too loose, therefore providing the correct tension needed for an efficient engine.

What Happens if a Chain Tensioner Assembly is Broken

If the chain tensioner assembly fails, the timing chain may become too loose or too tight. This varying tension can lead to a variety of problems, including engine misfires or complete engine failure. Signs of a faulty chain tensioner assembly may include a rattling noise from the engine, poor engine performance, or the 'Check Engine' light on your dashboard.
