Get it in the garage if you can,heated or not.Ive used a salamander heater before useing old tarps to make a tent over the front half of the vehicle and the heater.Make sure the tarp is over the top of your heat sorse a couple feet.Ive melted a few.Also have the hood open and the radiator cap off so air can circulate.One of the first things to look at when starting is the temp guage.With the heater on high and the engine running youl notice that the temp guage rised but your only getting cold air from the heater.If its frozen youll peg the guage pretty quickly.
