ENGINE COOLANT HEATER (ENGINE
BLOCK HEATER) (OPTION)
(CANADA ONLY)
In very cold weather, O°F (-1S”C) 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 outlet.
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 fie. You could be seriously injured. Plug
the cord into
a properly grounded three-prong 110-volt outlet. If
the cord won’t reach, use a heavy-duty three-prong extension
cord rated for at least 15 amps.
NOTICE:
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 weather, the kind
of oil you have, and some other things.
Instead
of trying to list everything here, we ask that you contact a Cadillac
dealer in the area where you’ll be parking your vehicle. The dealer can
give you the best advice for that particular area.
