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
1
10-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.
4.
Before starting the engine, be sure to unplug and
store the cord as
it
was before to keep it away from
hot pipes, manifold or 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 Chevrolet dealer in the area where you’ll be
parking your vehicle. The dealer can give you the best
advice for that particular area.
