A year ago I got a Forester petrol. Built 2009. Now the workshop thinks that with regard to the age (only 56000km on it) the timing belt is to be changed, which surprises me, since I had a timing belt change so far with used vehicles of other manufacturers so about 100 – 120 000Km, with these vehicles usually around the 7 -10 years were timing belt destruction at the Subaru-Forester petrol 7 years and 56000km?
