What is the recommended period to change the cambelt on a 1.8K Series. Looking through my owners hand book it says 48,000 miles. My service record shows it was done by the previous owner in 2012, at the time the car was 8 years old but had only done 4500 miles. 7 years later it's on 11000 miles. I'm guessing I need to get it done soon by virtue of age if not miles,am I right? What else should I look to be getting done at same time, water pump? Any and all advice welcome, thanks in advance.
