DON'T LEAVE IT TOO LATE!
It may not sound like much, but the cambelt is essential to the welfare of your Nissan.
The cambelt ensures that the moving components within your engine are all kept in perfect timing. As the rubber belt will start to deteriorate over time, it is a Service item and will need replacing periodically.
We recommend that you change it every 5 years or every 90,000 miles, whichever comes first. If you leave it too late and the belt fails, there is a high probability of major engine damage and your car could require a new engine.
