Your INFINITI's timing chain ensures that the engine valves open and close at the correct intervals. It's important that the timing chain has a balanced 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 that the timing chain maintains the correct tension level to keep your engine running as designed.

Eventually, your vehicle's timing chain can loosen. The Engine Timing Chain Tensioner is there to make sure the timing chain stays in place and under the appropriate amount of pressure, even if any stretching occurs. 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. Without a functioning timing chain, 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 sound coming from under the hood. If you hear a metal-on-metal sound, it might signify that the timing chain is loose and might be worn out. In time, a rattling loose timing chain can lead to other issues, such as oil leaks.

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 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. Get help with professional installation at your nearest authorized INFINITI service center.
