When to change an Opel Astra's timing belt?

Hi Eddie,

You've not told us what engine you mean, so here's a list of the most common engines. Note that timing chains don't have a change interval and they should last the life of the engine if scheduled oil changes are carried out and all else is well.

 - 1.2-litre petrol: timing chain
 - 1.3-litre CDTi diesel: timing chain
 - 1.4-litre petrol: timing chain
 - 1.6-litre petrol (both turbo and NA): timing belt - change every 150,000km or 10 years
 - 1.7-litre CDTi diesel: timing belt - change every 150,000km or 10 years
 - 1.8-litre petrol 125hp: timing belt - change every 90,000km or six years
 - 1.8-litre petrol 140hp: timing belt - change every 150,000km or 10 years
 - 1.9-litre CDTi diesel: timing belt - change every 150,000km or 10 years
