yes, well maybe the 2.5 liter engines have a chain, that's a v6 i think, dunno about the diesels.
No its a timing chain, Which does not need to be replaced...
It's a cambelt.
vauxhall recommend 100,000 miles or ten years
1-3-4-2 #1 being at the cambelt end of the engine.
i paid £100
Have recently just had mine done on a 52 vectra at 65,000 but l think this was a little late vauxhall recommend 40,000 but you have to renew all tensioners and waterpump, comes as a kit, costs me £200 to have this done at my local garage.
