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 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 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 receives the proper amount of tension 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 correct amount of pressure, despite any stretching that might 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 engine won't be able to operate.

If your Engine Timing Chain Tensioner needs to be replaced, you may notice a rattling noise coming from your engine. A metal-on-metal sound may mean the timing chain has too much slack in it and is starting to wear out. Eventually, a timing chain that has become loose may lead to other troubles, like an oil leak.

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 accessing the Engine Timing Chain Tensioner can be difficult.

If your Engine Timing Chain Tensioner needs to be replaced, we recommend that you replace it with a genuine tensioner from INFINITI Parts. Locate your nearest authorized INFINITI service center for professional installation.
