When to change timing belt on 2009 Ford Fusion?

The timing belt on a 2009 Ford Fusion should typically be replaced every 100,000 to 120,000 miles, or according to the maintenance schedule outlined in the owner's manual. It's important to inspect the belt regularly for signs of wear, such as cracks or fraying. If you notice any unusual noises from the engine or if the vehicle has difficulty starting, it may be wise to have the timing belt checked sooner. Always consult a professional mechanic for specific recommendations based on your vehicle's condition.
