Tensioner Belt.
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

The timing chain in your INFINITI 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 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 INFINITI maintains the correct tension level to keep your engine working like it's supposed to.

Your INFINITI's timing chain may become loose over time. The Engine Timing Chain Tensioner helps keep the timing chain in the right place and under the appropriate amount of pressure, regardless of any stretching that may occur. If the Engine Timing Chain Tensioner on your vehicle is broken or worn out, it could cause the timing chain to become loose 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 valves and pistons can collide, and your INFINITI's engine will be unable to run.

One obvious sign of an Engine Timing Chain Tensioner that needs to be replaced is a rattling sound coming from under the hood. A metal-on-metal sounding rattle could signify that your timing chain has lost tension and might be worn out. Over time, a timing chain that has become loose may lead to other troubles, like an oil leak.

If you suspect your INFINITI's Engine Timing Chain Tensioner is damaged or failing, 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 it's time to replace your Engine Timing Chain Tensioner, purchase a new replacement tensioner from genuine INFINITI Parts. Locate your nearest authorized INFINITI service center for professional installation.
