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 majority of the cost is labor, because many parts need to be removed from the engine to gain access to the belt. A typical timing belt will only cost between $25 and $50, but the repair takes at least a few hours. The labor cost to replace a timing belt can range from $200 â $900. Timing belt replacement should be conducted by a professional mechanic as it is an advanced project that requires one to disassemble the engine to be able to remove the old belt.
