    With the polar vortex upon us how cold does it have to get for you not to shut off your truck for anything........?


    My personal line is -15F . At that temp she runs period. All night/day whatever...

    Added fuel treatment (double dose) and hit the air system twice with alcohol ...

    How do you add alcohol to air system on the truck?

    I set my barrier at about minus 10 depending on the wind .

    Couple of ways....

    Pull main supply line off compressor and dump it in there . It’s not great for your air drier cartridge but it beats a frozen line...

    Also I dump some in the tank directly. ...

    And finally fill the glad hand lines for the trailer....

    Why do you guys use the weather channel term - polar vortex?

    It is an arctic blast. :)

    The wind doesn't really matter, the temps on the truck won't drop beyond -10 if the air temps are -10.

    By the way, I ask to keep the trucks running when it hits 10 degrees, hi-idle and not put on defrosters, just plain heat with no air on.

    I'd say depends if you have treated fuel. I caught hell the other day when my reefer gelled the fuel. Forgot last time I filled it was with Georgia fuel. Even though it was running nonstop it froze up at -1 in Wisconsin. That was a $283 bill at transport refrigeration.

    I’m guessing reefers don’t return any fuel to the tank......?

    They return a little but not much ...anything below 10 mine goes to continuous and always on continuous overnight when cold .
    Never had a problem but most of my fuel is bought in northern states .
