Engine Heater - Chevrolet Malibu 2012 Owner's Manual

9-20 Driving and Operating

Engine Heater

The engine coolant heater can
provide easier starting and better
fuel economy during engine
warm up in cold weather conditions
at or below 18°C (0°F). Vehicles
with an engine coolant heater
should be plugged in at least four
hours before starting the vehicle.
An internal thermostat in the
plug-end of the cord may exist
which will prevent engine coolant
heater operation at temperatures
above 18°C (0°F).
To Use the Engine Coolant
Heater
1. Turn off the engine.
2. Open the hood and unwrap the
electrical cord. With a 4 cylinder
engine, the engine coolant
heater cord is located near the
air cleaner box on the passenger
side of the engine compartment.
With a V6 engine, the engine
coolant heater cord is located
on the driver side around the
battery box. See Engine
Compartment Overview on
page 10 6 for more information
on location.

WARNING
Plugging the cord into an
ungrounded outlet could cause an
electrical shock. Also, the wrong
kind of extension cord could
overheat and cause a fire.
WARNING (Continued)
You could be seriously injured.
Plug the cord into a properly
grounded three-prong 110-volt AC
outlet. If the cord will not reach,
use a heavy-duty three-prong
extension cord rated for at least
15 amps.
3. Plug the cord into a normal,
grounded 110-volt AC outlet.
4. Before starting the engine, be
sure to unplug and store the
cord as it was before to keep it
away from moving engine parts
and prevent damage.
The length of time the heater should
remain plugged in depends on
several factors. Ask a dealer in the
area where you will be parking the
vehicle for the best advice on this.
