Brrr! The weather is definitely getting colder and having enough heat in your car is important. Not only to keep our bodies warm, but also because heat is needed to remove any fog or ice build-up on your windshield.
There are a few reasons why your car’s heater is not getting hot enough. First, your car may need more antifreeze in the radiator. If this is the case, there most likely is a leak somewhere in the system.
Another reason for low heat would be a bad thermostat. A thermostat maintains an engine’s optimum operating temperature by regulating the flow of coolant to the radiator.
