Engine Coolant Heater - Pontiac G6 2009 Owner's Manual

Engine Coolant Heater

The engine coolant heater can provide easier starting
and better fuel economy during engine warm-up in cold
weather conditions at or below 0°F (−18°C). Vehicle
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
0°F (−18°C).
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
On the 2.4L L4 ECOTEC
coolant heater cord is located near the air
cleaner box on the passenger' side of the
engine compartment. On the 3.5L, 3.6L and
3.9L V6 engines, the engine coolant heater cord is
located on the driver side around the battery box.
See Engine Compartment Overview on page 5-14
for more information on location.
3. Plug the cord into a normal, grounded 110-volt AC
outlet.

CAUTION:
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.
The length of time the heater should remain plugged
in depends on several factors. Ask a dealer/retailer
in the area where you will be parking your vehicle for
the best advice in this.
