Hello all, apologies as this has more than likely been asked before however I couldn't find my answer on a search...
I have a Z20LEL engined Astra on a 54 plate, I just booked in for a service and MOT.
I asked about getting the timing belt and tensioners changed as the service booklet (if I am reading it right) says it is 6 years or 60k miles.
However, the girl at service reckons she has checked with the tech and it is not due until 10 years or 100k miles.
Can anyone confirm please, what is the correct interval for the timing belt & associated bits on this engine?
