The Greenfield Fire Territory participates in the Hancock County Technical Rescue Team. The Team was created to pool the resources of the Greenfield Fire Territory and the Sugar Creek Township Fire Department to enhance the response to technical rescue situations. The Greenfield Fire Territory is the busiest fire department in Hancock County, responding to more than 3400 emergency calls annually. Approximately 80% of those calls are emergency medical responses.
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.
By the past I'm referring to the infamous Fiat timing belts of the 70's. If you didn't change these belts on the exact mileage they specified, then you could almost guarantee that it would break and total the engine. Their expected life span was no more than 30,000 miles max if I remember correctly.
