Engine Coolant Heater
The engine 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 heater should be plugged in at least
four hours before starting. 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).
If the vehicle has the DURAMAX
®
Diesel engine, see
the DURAMAX
®
Diesel manual for more information.
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord. The
cord is secured to the Engine Compartment Fuse
Block with a clip. Carefully remove the wire tie
which bundles the electrical plug. Do not cut the
electrical cord.
3. Plug the cord into a normal, grounded 110-volt AC
outlet.
{
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.
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.
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. If you do not, it could be
damaged.
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.
