Guide Chain, Slack Side.
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 on your vehicle ensures that the engine valves open and close at the correct 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. Your vehicle's Engine Timing Chain Tensioner makes sure the timing chain has the right amount of tension to keep your engine running as designed.

Your INFINITI's timing chain may become loose over time. The Engine Timing Chain Tensioner keeps the timing chain in the correct position and under the right 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. If your timing chain isn't working as it should, the engine pistons and valves may 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 noise around the engine bay. 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 rattling loose timing chain can lead to other issues, 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 it can be a difficult process accessing the Engine Timing Chain Tensioner.

If your Engine Timing Chain Tensioner needs to be replaced, purchase a new replacement tensioner from genuine INFINITI Parts. Locate your nearest authorized INFINITI service center for professional installation.
