On a Mazda 3, the cam belt (timing belt) should be changed every 60,000 to 100,000 miles, depending on the specific model year and engine type. It's crucial to consult your owner's manual for the manufacturer’s recommendations. Additionally, if you notice any signs of wear, such as cracking or fraying, it's advisable to replace the belt sooner. Regular maintenance can prevent engine damage and ensure optimal performance.
