Engine Coolant Heater (If Equipped)
2.4L Engine
3100 Engine
In very cold weather, 0°F (- 18 O C) or colder, the engine
coolant heater can help. You’ll get easier starting and
better fuel economy during engine warm-up. Usually,
the coolant heater should be plugged in
a minimum of
four hours prior to starting your vehicle.
