Engine Heater

If the vehicle has a diesel engine,
see the Duramax diesel supplement
for more information.
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. 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.
The cord for the engine
coolant heater is located on
the driver side of the engine
compartment and is attached to
the hose for the power steering
reservoir.
3. Plug it 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
and prevent damage.
Driving and Operating
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.
