The cam belt (sometimes called the timing belt) on your Ford Fiesta 1.6 Zetec-S should be changed every 120,000 miles or every 10 years, whichever comes first. However, it's important to note that this is only a general guideline; the actual life of your cam belt will depend on several factors, such as:
* Driving conditions: If you drive in dusty or dirty conditions, your cam belt will wear out faster.
* Engine load: If you often carry heavy loads or tow a trailer, your cam belt will wear out faster.
* Climate: If you live in a hot or humid climate, your cam belt will wear out faster.
For these reasons, it's important to have your cam belt inspected regularly by a qualified mechanic, and to have it replaced if it shows any signs of wear. If your cam belt fails, it can cause serious damage to your engine, so it's important to take preventive measures.
Here are some signs that your cam belt may need to be replaced:
* A ticking or knocking noise from the engine
* A decrease in engine performance
* A rough idle
* A check engine light
If you experience any of these symptoms, it's important to have your car checked out by a qualified mechanic as soon as possible.
