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). Vehicles
with an engine coolant heater should be plugged
in at least four hours before starting. Some models may
have an internal thermostat in the cord 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. The
engine coolant heater cord is located near the air
cleaner box on the passenger side of the engine
compartment. See Engine Compartment Overview
on page 6-14 for more information on location.
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/retailer in
the area where you will be parking the vehicle for the
best advice on this.
