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 ensures the valves on the engine close and open and the proper intervals. It's essential that the timing chain has the proper tension to keep the rotation of the camshaft and crankshaft in sync and the valves of the engine closing and opening at the proper intervals. Your vehicle's Engine Timing Chain Tensioner makes sure the timing chain has the right amount of tension to keep your engine operating as it should.

Eventually, your vehicle's timing chain can loosen. The Engine Timing Chain Tensioner helps keep the timing chain in the right place and under the correct amount of pressure, despite any stretching that might occur. If the Engine Timing Chain Tensioner on your vehicle is broken or worn out, 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 valves and pistons can collide, and your INFINITI's engine will be unable to run.

A clear sign of a damaged Engine Timing Chain Tensioner may be a rattling sound coming from under the hood. If you hear a metal-on-metal sound, it might signify that the timing chain is loose and is probably starting to wear out. In time, a rattling loose timing chain can lead to other issues, such as oil leaks.

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

If it's time to replace your Engine Timing Chain Tensioner, purchase a new replacement tensioner from genuine INFINITI Parts. Find your closest authorized INFINITI service center for help with professional installation.
