    I recently pulled my radiator to have it flushed and fix a few cracks. I disconected the overflow container to use the connections for hooking up to something else. About how much fluid should i put in my radiator?

    Would you sugest a 50/50 mixture of water/anti-freeze?

    Only if you will be were it gets really cold !
    Try to guess the coldess it will be and give your guess an extra 10 degree's.
    When I lived in Seattle winters got to 20 degs once every 10 years, so I figured it may get to 10 degs.
    Depending on your flavor of Anti- frez, usually on the back it will tell ya what ratio will egual what degs.
    More is always better ?
