    Zafira B Cambelt Intervals

    Hi

    This may seem like a daft question but my dad and I are moving to Zaffy B's within this week and I am wondering though when the cambelt kit and waterpump should be replaced?

    06 & 56 plated cars

    My mum however still has her Zaffy A and loves it so shall get to drive both styles.

    I have been told the new timing is 100k or every 10yrs is this right?

    Cheers

    Roy

    Cambelt interval depends on the engine - many petrol Vauxhalls were originally down as an80,000 mile interval, however as many were snapping around the 50-56,000 mark, they reduced this to every 40,000 miles. No idea on more recent engines, or those with timing chains and not belts.

    On the CDTi diesels, the official figure is 100000 miles or every 10 years. However, what has happened to some is for the water pump to fail around the 60000 mile mark and throw off the still-intact cambelt.

    For the 16v CDTi this isn't as terminal as it sounds, as it has special rocker arms that snap if the cambelt or pump goes... this protects the valves from the impact of the pistons, meaning you'll just need to replace the snapped rockers and cambelt/water pump and you're good to go again! Head removal not required

    The 8v on the other hand doesn't benefit from this, so if the cambelt goes it's probably toast.

    I would say the basic rule applies: if you don't know for certain, get it done.

    I don't understand why they can't do this for all models, or is a money making ploy? Am I being too cinnical?

    Blimey god knows now lol the car i am moving to is nothing really special its a 1.6 16v again and is basic which means I can add my small touches like tints wheels etc which are planned for in the new year.

    Are the 1.6 chain or belt driven?

    Cheers

    In that case, 40000 is the magic number

    And they are belt driven.

    Change interval for the 1.6 and 1.8 litre engines is 150000km (~95k miles) or 10 years and for the 2.0 Turbo 120000km (~75k miles) or 8 years.
    2.2 is chain driven.
    For 1.9 diesels it's 150000km (~95k miles) or 10 years.
