The timing chain in your INFINITI ensures that the engine valves open and close at the correct intervals. The timing chain must have the right amount of tension to keep the camshaft and crankshaft's rotation in sync and make sure the engine valves are opening and closing at the right 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.

Over time, your INFINITI's timing chain can stretch. The Engine Timing Chain Tensioner helps keep the timing chain in the right place and under the appropriate amount of pressure, even if any stretching occurs. If your vehicle's Engine Timing Chain Tensioner is damaged or old, it may cause the timing chain to loosen and fall out of place. This could cause the timing chain to break if the vehicle is running when it happens. Without a functioning timing chain, the engine pistons and valves may collide, and the engine might stall.

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 is starting to wear out. Eventually, a loose timing chain may lead to additional problems, such as 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 it's time to replace your Engine Timing Chain Tensioner, we recommend that you replace it with a genuine tensioner from INFINITI Parts. Get help with professional installation at your nearest authorized INFINITI service center.
