It is connected to normal AC power overnight or before driving, via regular power plugs that are fed through a vehicle's grille. This allows easier starting in cold temperatures, by keeping the coolant warm. Heater is also available for motor oil so that the oil does not gel and its viscosity remains low. The rapid heat circulation caused by block heater also aids the initial vaporization of fuel in the engine; because of this effect, block heater reduces pollution, as poor fuel vaporization causes much higher emissions.
