    4WD Radiator - Is the second radiator always in use?

    Hello all,

    So I have the second, horizontal radiator below my AC condenser. Is the second radiator always in use once the thermostat is open? Is there any valving or additional thermostat between the second radiator and the main radiator?

    As far as I know, that second 'horizontal radiator' is the evaporator for you air-con, not a second motor radiator, and they do not share fluids.

    On my van, there is the horizontal AC condenser in the normal place, and directly below it is a second motor radiator. Here is the diagram for the second radiator.

    I drained my whole system from the horizontal one, I feel if there was valving it would not have drained or refilled properly. Make sense?
