Gears
No its all connected by gears.
Engine code X22DTH This engine is fitted with a timing chain
At about 51000 miles for 1.8 petrol
All Vauxhall 2.2 petrol engines in Astra and Zafira have a chain. The Sintra and the Omega are belt driven as they were fitted with what was in effect a bored out version of the X20XEV which was belt driven.
This is Not a chain Nor a belt if it is the 2.5TDS. This engine is timed using 'geared pulleys' just like a Gearbox. There is no requirement for adjustment or replacement of anything to do with timing. If it is anything other than this It will more than Likely be a chain if it's diesel or belt if it is the vauxhall petrol engine depending on the size of the engine. I have a 1998 2.5 TDS LWB Frontera which doesn't require either!
Its a belt but its the rollers that fail check out www.v6technicians.co.uk they know all bout this engine It has a timing belt. Only some diesels or the 2.2 petrol Vectra's have timing chains.
Which engine?

Belt :)
The timing belt on a Vauxhall Astra 55 petrol model should typically be changed every 60,000 to 100,000 miles, or according to the manufacturer's recommendations found in the owner's manual. It's also advisable to replace the timing belt if there are any signs of wear, such as cracks or fraying. Regular maintenance checks can help ensure the timing belt is in good condition, as a failure can lead to significant engine damage. Always consult a qualified mechanic for personalized advice.
Timing belts normally changed every 60,000 miles but if just aquired the car best to get a new one on for peace of mind
