When Should I Change The Timing Belt? The US service manual states that the timing belt should be replaced at 72 months (6 years) or 90,000 miles. The vast majority of NSXs hit 6 years well before they are anywhere near 90k miles so many owners are wondering if they really need to change the belt at 6 years. The safe answer is to replace it per the maintenance schedule.
The expected lifespan of your timing belt is specific to your car and engine configuration, usually between 60,000 and 100,000 miles. The manufacturer's recommended intervals are a safe guideline; you probably won't need to replace your belt any earlier [source: Allen].
