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.
Replacing a timing belt is a more involved and costly procedure, typically running from at least $500 to more than $1,000, depending on vehicle. Even worse, on some engines if the timing belt breaks, the pistons may continue to move up and down, and in the process bend valves that have lost their timing mechanism.
