When to change my Ford C-Max's timing belt?
When should I change the timing belt on my 2011 Ford c max automatic 2.0l t
Our answer:
Hi Sheila,
The pre-2011 2.0-litre petrol engine used a timing chain, so we assume you mean the 2.0-litre diesel engine. Its belt should be changed at least every 200,000km or 10 years - whichever comes first.
