To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The engine coolant heater cord is located near
the engine air cleaner/filter.
3. Plug i
.
lto a normal, grounded 1 IO-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 dealer in the area where you'll be parking
your vehicle. The dealer can give you the best advice for
that particular area.
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.
