Duster Survivor Radiator Dilemma

FROM STANT i stand corrected... i wonder why they sold them before as i was saying.. thats the selling point that hooked ,e on them years ago.... bad stant..bad!

Does Stant have a fail safe thermostat?
All thermostats will fail in either a closed or open position; there is no such thing as a thermostat that will fail in a “safe” position. Although some brands may claim a thermostat fails in a safe position, it simply locks itself open while it is in a full stroke open position. It will not spring open if it fails in a closed position.
