The timing chain on your vehicle ensures the valves on the engine close and open at the proper intervals. It's essential that the timing chain has the proper tension to keep the camshaft and crankshaft's rotation in sync and the engine valves opening and closing at the correct intervals. The Engine Timing Chain Tensioner ensures the timing chain in your Nissan has the right amount of tension to keep your engine working like it's supposed to.
Over time, your Nissan's timing chain can stretch. The Engine Timing Chain Tensioner helps keep the timing chain in the right place and under the right amount of pressure, despite any stretching that might occur. If your vehicle's Engine Timing Chain Tensioner is damaged or old, it could cause the timing chain to become loose and fall out of place. This could cause the timing chain to break if the vehicle is running when it happens. Without a functioning timing chain, the engine pistons and valves may collide, and your Nissan's engine will be unable to run.
If your Engine Timing Chain Tensioner needs to be replaced, you may notice a rattling noise coming from your engine. A metal-on-metal sounding rattle could signify that your timing chain has lost tension and is probably starting to wear out. In time, a loose timing chain may lead to additional problems, such as oil leaks.
If you think the Engine Timing Chain Tensioner on your vehicle is old or damaged, it's important that a professional technician inspect the tensioner to repair or replace it, as accessing the Engine Timing Chain Tensioner can be difficult.
If it's time to replace your Engine Timing Chain Tensioner, we recommend that you replace it with a genuine tensioner from Nissan Parts. Locate your nearest authorized Nissan service center for professional installation.
