However, it's important to note that this replacement interval is based on normal operating conditions. If the vehicle is driven in severe conditions, such as dusty, muddy, or wet environments, or if it's used for towing or racing, the timing belt may need to be replaced more frequently.
It's always a good idea to consult with a qualified mechanic or refer to the specific maintenance schedule for your vehicle's model and year to determine the exact timing belt replacement interval for your 2004 Ford Mustang V6.
