Engine Coolant Heater (Option)
In very cold weather, 0°F
(- 18 O C j or colder, the
engine coolant heater
can help.
A 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 won’t reach, use a
heavy-duty three-prong extension cord rated
for
at least 15 amps.
You’ll 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.
To Use the Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
3. Plug it into a normal, grounded 110-volt AC outlet.
~
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 don’t, 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
GM dealer in the area where you’ll be parking your
vehicle. The dealer can give you the best advice for that
particular area.
