    I wonder if anyone can help?.. for the last 13 years I have owned a
    virtually trouble-free Astra 1.6 petrol estate and have replaced the cam
    belt on several occasions, I have never experienced any problems setting the
    belt tension by twisting it through 90 degrees.

    However I have just acquired a very sound diesel version which is fitted
    with the 17D engine, not knowing when the belt was last changed I would like
    to replace it as soon as possible, I appreciate that I will have to use a
    cam shaft alignment tool , however on the several sources I have looked at
    there appears to be dire warnings about failing to use a tension meter, can
    I still use the method I used on the old petrol version, or will this lead
    to premature belt failure?

    Thanks in advance.

    If I remember correctly the tension pulley has markers on it, So you can
    tell if it has the correct tension.
    Don't think it matters if the belt snaps, it's not know as an interference

    Thanks, but as far as I can gather the 17D engine still retains the water
    pump as the adjuster, it's the17DR and 17DTL engines that have the

    Had one of these - - if the cambelt breaks it damages the engine. The
    valve rockers are designed to break (on the Vauxhall engine) and are
    relitivly cheap to replace. However the engine can be damaged such that
    the cylinder head has to come off to replace a bent valve (he says
    looking at the £300 bill).
    I strongly advise you to change the water pump and belt tensioner at the
    same time.
    Guess how I found out?

    Thanks Dave for your comments, however I still need to know if it's possible
    to ajust the belt 'by eye', or whether It's 'essential' to use the correct
    tensioning meter and cam locking tool, in which case unless I can hire a kit
    at a reasonable price, it may be cheaper and a lot less hassle to get the
    job done through a local Vauxhall agent.

    Any decent Garage will be able to do the job. They have a book with
    tools and settings etc. Last but one cambelt change on SWMBO Astra ('94
    1.7D no turbo) cost about £100. Water pump replaced at the same time
    because there was excessive play in the bearings. It was making a
    horrendous knocking noise, a very, very lound metalic "clack". Belt
    broke 18 months later because of a "forign object in the casing". Hey Ho
    goodbye £300 (rocker arms etc).

    Thanks again for your input Dave, I was lucky with this one, I recently
    bought it for £200, H Reg with 117,000 miles on the clock, two local owners
    [I knew the last one] and body wise in virtually showroom condition, so
    worthwhile spending money on getting it up together, there was only 50 miles
    on the clock between the last two MoT certificates!

    The previous owner had died and his widow just wanted to be rid of it,
    however I don't think the months of standing around without being used has
    done it any favours, as judging by the amount of juddering when accelerating
    and de-accelerating I suspect an engine mount/s have given up the ghost,
    otherwise a very nice drive, so tomorrow it looks like another thing that I
    will have to try and find out about is would it be advisable to change all
    three mounts, how difficult would that be, and roughly how much would it

    No idea on costs I'm afraid.
    There is a throttle damper fitted above the injector pump. On SWMBO
    Astra it had seiezed making the throttle action very stiff there was a
    little judder when it was removed.
    Water in the diesel filter (replace it about £8) or oil/rust on the
    clutch face would also cause the same judder. Don't know how much
    clutches cost but there wasn't a lot of adjustment left on the old Astra
    when it was part/exed last week at 95,000 miles so yours could be shot?

    Again thanks for your pointers Dave, however I'm pretty certain that it's an
    engine mount/s, especially as the guy who put it through its MoT reckoned
    that one was 'soft', I'll let you know how I get on.
