Block heaters are generally an optional piece of equipment installed at the dealership in northern climates. They are installed in holes in the engine block where the frost plugs are normally located (frost plugs allow freezing coolant to expand without cracking the engine block). Best way to tell if your car has a block heater is to look for the 110V cord and plug poking out from the front grille. If it has one, plug it in when the temperature is forecast to drop below -10 C (20 degrees F) overnight.
