    Get yourself a can of dye penetrant & start looking for cracks.

    You could drill a ⅛" hole on the flange.

    Radiator good? At this point keep an eye on everything, belt adjustment, coolant level.

    How cold do you get there at night?

    Put in antifreeze, change the oil...what else?
    Fire it up, then retourqe the bolts after it warms up

    Radiator is brand new. i expect it to last longer than anything else.

    In fact, no more than 50/50. It's protection qualities actually diminish as it goes beyond 50%

    its been unseasonably warm, with temps in the low 40's.
    after tonight though, the hammer drops. freezing temps for the next 5 months. I love WI weather. tonight will be the last night of me working comfortably in my unheated shop.
