To Use the Engine Coolant
Heater
1. Turn off the engine.
2. Open the hood and unwrap the
electrical cord.
The cord for the engine coolant
heater is located on the driver
side of the engine compartment
and is attached to the hose for
the power steering reservoir.
3. Plug it into a normal, grounded
110-volt AC outlet.
WARNING
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.
WARNING (Continued)
Plug the cord into a properly
grounded three-prong 110-volt
AC outlet. If the cord will not
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 moving engine parts
and prevent damage.
The length of time the heater should
remain plugged in depends on
several factors. Ask a dealer in the
area where you will be parking the
vehicle for the best advice on this.
