Engine Coolant Heater

In very cold weather, 0°F (−18°C) or colder, the
engine coolant heater, if your vehicle has this
feature, can help. You will get easier starting
and lower fuel usage during engine warm-up.
Usually, the coolant heater should be plugged in
a minimum of four hours prior to starting your
vehicle. At temperatures above 32°F (0°C), use of
the coolant heater is not required. Your vehicle
may also have an internal thermostat in the
plug end of the cord. This will prevent operation of
the engine coolant heater when the temperature
is at or above 0°F (−18°C) as noted on the cord.
