Engine Coolant Heater

Your vehicle may have an engine coolant heater.

In very cold weather, 0°F (−18°C) or colder,

the engine coolant heater can help. You will get

easier starting and better fuel economy during

engine warm-up. Usually, the coolant heater

should be plugged in a minimum of four hours

prior to starting your vehicle. At temperatures

above 32°F (0°C), use of the coolant heater is

not required.

To Use the Engine Coolant Heater

1. Turn off the engine.

2. Open the hood and unwrap the electrical

cord. The cord is located on the driver

side of the engine compartment, behind the

battery.

3. Plug it 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. If you do

not, it could be damaged.

How long should you keep the coolant heater

plugged in? The answer depends on the outside

temperature, the kind of oil you have, and some

other things. Instead of trying to list everything here,

we ask that you contact your dealer in the area

where you will be parking your vehicle. The dealer

can give you the best advice for that particular area.
