- 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. The timing chain must have the right amount of tension to keep the crankshaft and camshaft rotations synchronized 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 working like it's supposed to.
Your Nissan's timing chain may become loose over time. The Engine Timing Chain Tensioner is there to make sure the timing chain stays in place and under the right amount of pressure, even if any stretching occurs. If your vehicle's Engine Timing Chain Tensioner is damaged or old, 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 your timing chain isn't working as it should, the valves and pistons can collide, and your Nissan'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 starting to wear out. Eventually, a rattling loose timing chain can lead to other issues, such as an oil leak.
If you suspect your Nissan'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, we recommend that you replace it with a genuine tensioner from Nissan Parts. Find your closest authorized Nissan service center for help with professional installation.
