When to change a cam belt on a 207 hdi?

The cam belt on a Peugeot 207 HDi should typically be changed every 100,000 miles (approximately 160,000 kilometers) or every 10 years, whichever comes first. It's essential to consult your owner's manual for specific recommendations, as intervals can vary based on the engine type and driving conditions. Regular inspections should also be performed to check for any signs of wear or damage. If you're unsure, it's best to consult a professional mechanic.
