When should I change the cambelt of Astra 1600 petrol regular, 2018. Done 39000 km.
Hi Tarek,
Assuming this is the non-turbo engine in the Astra J should be changed at least every 150,000km or six years - whichever comes first. However, most 2018 Astras would be the newer 'K' generation and the only 1.6 petrol engine is the turbocharged one, which has a timing chain, not a belt.
