In
very cold weather,
0°F
(-
18OC)
or colder, the engine
coolant heater can help. 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.

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.

After you’ve used the coolant heater, be sure
to
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 Buick dealer in the area where you’ll be parking
your vehicle. The dealer can give you the best advice for
that particular area.
