An oil pressurized tensioner that keeps the chain that runs from the crankshaft to camshaft or the chain that runs from camshaft to camshaft, from becoming loose and jumping a tooth or more causing engine damage or out of sync crankshaft to camshaft timing.

• Helps keep your engine operating as it should
• Ensures the timing chain receives the proper amount of tension
• Replace when worn out or damaged

Your INFINITI's timing chain ensures the valves on the engine close and open and the proper intervals. The timing chain must have the right amount of tension to keep the camshaft and crankshaft's rotation in sync and make sure the engine valves are opening and closing at the right intervals. Your vehicle's Engine Timing Chain Tensioner makes sure the timing chain receives the proper amount of tension to keep your engine working like it's supposed to.

Over time, your INFINITI's timing chain can stretch. The Engine Timing Chain Tensioner helps keep the timing chain in the right place and under the appropriate amount of pressure, even if any stretching occurs. If the Engine Timing Chain Tensioner on your INFINITI is worn out or damaged, 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. Without a functioning timing chain, the pistons and valves could collide, and your INFINITI's engine will be unable to run.

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, like an oil leak.

If you suspect your INFINITI's Engine Timing Chain Tensioner is damaged or failing, it's important to have a professional INFINITI technician inspect and repair or replace the tensioner, as accessing the Engine Timing Chain Tensioner can be difficult.

If you need to replace your Engine Timing Chain Tensioner, replace it with a new OEM replacement tensioner from INFINITI Parts. Get help with professional installation at your nearest authorized INFINITI service center.
