    Ram air adds air to the intake, not air through the radiator...so no.

    Make sure you have a good radiator, thermostat and drive with the plow a little low to allow airflow.

    Drive with the plow down as low as possible angled to the right. This comes right out of an 80's Myer install guide (for Ford). Try different positions.
    You may need a new fan clutch, the fan should be "roaring" when it's hot.
    To test it, the book says to block the radiator (Grill side) with a piece of card board turn heater off and listen for the fan to engage,just don't let it over heat real bad.
    The fan blades may be tried too,mine were so rusted I was afraid one would fly off some day. Belt/belts may need replaced or adjusted.
    If all else fails engage emergency cooling---> Heat set to vent and blower on high.
    If it starts to run hot plowing, I pop the hood and let the safety catch hold it from coming open for more air flow.
