    What antifreeze should I put into this thing? AIUI, they're somewhat
    fussy (the 2.5l aluminium straight-6) and the earlier 3l had an
    infamously poor reputation for block leak problems, whether caused by
    poor castings or by incorrect antifreeze.

    Unipart have just given me the "They're all the same, guv" response.
    They also offered an OAT, which could have been made from oatmal for all
    the advice the guy in the shop could offer.

    I'm loathe to go and buy Volvo's magic fluid, because I doubt very much
    if it's any better than many other equally comparable products -- but
    how to tell ? Is there any standard quality rating system for
    antifreeze? What is the Volvo stuff anyway, just a corrosion inhibited
    ethylene glycol with a low phosphate content?

    Even my Bosch handbook seems quiet on antifreeze grading. Is a more
    recent edition (6th or 7th) any more informative?

    Thanks for any advice

    The Saab guys swear by Mercedes antifreeze. It's not super expensive and it
    plays nice with alloy engines. The 900 engine is prone to head gasket
    failure if you use the green stuff in it.

    Seems to be some 'alchemy' surrounding antifreeze. Any good ethelene gylcol
    based stuff will do. Important thing is concentration and to change when

    I've heard bad things about the composition of the 'green' stuff
    (phosphates) but we don't get it in europe...

    That certainly isn't true. Neat ethylene glycol might be a great
    antifreeze, but it's not a corrosion inhibitor.

    Also a number of major car makers in the last 15 years have switched to
    "long life" coolants. Ford went with organic acids, others (including
    Volvo) found some variant of ethylene glycol. "Simple" ethylene glycols
    aren't a substitute for either.
    Yes we do.

  5. Make sure you get pure anti freeze as some are full of water and a tad of
    anti freeze .Make sure its a top brand not a unknown who cares product .Be
    sure its rated for anti freeze anti corrosion anti boil,all three .Mke sure
    its for aluminuim .BP SHELL ESSO MOBIL NULON CASTROL .The blocks had a
    problem with thin wall porosity ..

    Zerex G-05 fluid is my choice for modern Volvos. It is specifically
    approved by Mercedes and is a very similar formulation to the Volvo
    factory stuff.

  7. I think pretty well all decent anti-freeze is now suitable for aluminium
    engines - unlike at one time. I've been using Halfords stuff for many
    years on my Rover SD1 which has an all alloy engine (apart from the twisty
    bits obviously) and recent examination showed the interior of the water
    jacket to be like new. I change it every couple of years. Usually because
    a hose has burst etc rather than scheduled. ;-)

    Are you in Europe? AFAIK, Valvoline don't supply it around here (UK)
    Does anyone know a UK source for it?

    I'm also a bit surprised - I thought this was an OAT coolant, and the
    Volvo one wasn't?
