    Default What to do when you loose your radiator cap.

    I saw this the other day and realizied there is always another way to do things.
    IF you keep finding the rad cap missing this is a sure way to fix it even if it does not have a pressure valve.

    That looks exactly like mine, the Old Farmer I bought it from lost the cap some where along the line. Just need to keep a little antisieze on the plug.

    Thats an affirmitive on that point, I learned at a real early age from my Dad to "make do" with what you've got to work with.

    Maybe that Cat is a puker and the cap is an attempt to keep coolant in it.

    Tough time's or parts scarce/goldplated maybe in the 50s in north Q.L.D. or both??

    This rotor came with the first cat I brought 5u 12968 which ran the pony great! I replaced it with a new goldplated rotor and put the hand crafted one back in the new box!!

    Default rad cap

    My 30 with the cold weather package has a threaded rad cap that looks just like the one that just sit in the radiator. Jason

    What would you think they've used for welding rod? - it looks very shiny given its years....

    If I was going to weld a pipe fitting like that onto the cast iron top, I'd have used a high nickel content rod; Ni Rod 66 or 99. That's about what it looks like was used. .or something similar.
