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.
Most dealers recommend changing the timing belt every 90,000 miles. Depending on driving habits and conditions the belt may last longer. I have heard of belts lasting 180,000 miles! The first gen LS's (1990-1994) have a non-interface engine, so if the timing belt breaks it's not going to damage the engine. If it breaks you'll just be stranded.
