I have 2006 Blazer. Antifreeze needs to be at right level or no heat. Instead of changing my thermostat for very cold temperatures I use a grill snap on guard that adds plenty of heat to the cab and is adjustable. Gasoline will not burn well if the engine is too cold in severe winter driving. If you are losing at lot of antifreeze use the copper sealer and not the aluminum sealers.
