Engine Coolant Heater
(If
Equipped)
In
very cold weather,
0°F
(-
18°C)
or colder, the
engine coolant heater
can help.
3. Plug
it
into
a
normal, grounded
1
IO-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.

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 Engine Coolant Heater
1.
Turn off the engine.
2.
Open the hood and unwrap the electrical cord.
The engine coolant heater electrical cord
is
located
on
the
driver's side
of
the engine compartment, near
the power steering reservoir.
4.
Before starting the engine: be sure to unplug and store
the cord
as
it
was before to keep
it
away from moving
engine
p~u-ts.
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 dealer
in
the area where
you'll
be parking yo~~r
vehicle. The dealer can give you the best advice
for
that
particular area.
