The 2005 Ford Focus MK2 1.6 100 bhp engine is equipped with a timing belt (cambelt) rather than a timing chain. It's important to adhere to the manufacturer's recommended replacement interval for the cambelt to avoid potential engine damage. Always refer to the owner's manual or a trusted mechanic for specific maintenance guidelines.
About 50,000 miles is recommended for ALL serpentine belts.
