BELT UP

I recently bought a 2007 Volvo C30 T5 with 100,000km. I’m confused as to when the timing belt should be replaced, with different sources — people and online — saying it should be after 10 years/150,000km, or 12 years/ 180,000km. Can you help?

Volvo Australia is a more reliable source than online “experts” and its official line is: “Auxiliary belts, timing belt with tensioner and idler pulley are due to be replaced at 180,000km or maximum 10 years.” If the timing belt snaps your engine will be toast, so if the previous seller didn’t produce a receipt for the work, please get it done without delay.
