I installed this on my Ford Super Duty Diesel Truck to help with the engine getting too cold and not producing enough heat in the cabin. I live in Montana and it sometimes drops into the -20s F (ambient, -40sF with windchill).. routinely in the winter we are in the negative and nearly always below freezing. I would get 'luke warm' air from my heater on the really cold days which isn't great. Once I added this, I get good hot air form the heater in about 10-15 minutes in negative temps.
