The timing chain on your vehicle makes sure the engine valves are opening and closing at the right intervals. The timing chain must have the right amount of tension to keep the rotation of the camshaft and crankshaft in sync and the engine valves opening and closing at the correct intervals. Your vehicle's Engine Timing Chain Tensioner makes sure the timing chain maintains the correct tension level to keep your engine running as designed.
Over time, your Nissan's timing chain can stretch. The Engine Timing Chain Tensioner is there to make sure the timing chain stays in place and under the correct amount of pressure, even if any stretching occurs. If your vehicle's Engine Timing Chain Tensioner is damaged or old, the timing chain could lose tension and fall out of place. If the vehicle is running when the timing chain falls out of place, it could cause the chain to snap. If the timing chain isn't functioning, the pistons and valves could collide, and the engine might stall.
If your Engine Timing Chain Tensioner needs to be replaced, you may notice a rattling noise around the engine bay. A metal-on-metal sounding rattle could signify that your timing chain has lost tension and might be worn out. Over time, a loose timing chain may lead to additional problems, such as oil leaks.
If you believe your Engine Timing Chain Tensioner is damaged or worn out, it's important that a professional technician inspect the tensioner to repair or replace it, as the timing chain is typically difficult to access.
If your Engine Timing Chain Tensioner needs to be replaced, replace it with a new OEM replacement tensioner from Nissan Parts. Locate your nearest authorized Nissan service center for professional installation.
