To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord. The
cord is located in the engine compartment, on the
passenger’s side of the vehicle, near the right
side engine mount.
3. Plug it into a normal, grounded 110-volt AC outlet.
{
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 fire. You could be seriously
injured. 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. 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.
You may wish to use your coolant heater to improve
ease of starting at temperatures between 0°F (
−
18°C)
and
−
20°F (
−
29°C). Keep the coolant heater plugged in
for a minimum of four hours. At temperatures below
−
20°F (
−
29°C), the coolant heater should remain
plugged in for at least eight hours. It will not harm either
the coolant heater or the vehicle to leave the coolant
heater plugged in longer than the times stated. Be sure
to remove and store the cord before starting the
engine. See Diesel Fuel Requirements and Fuel System
on page 5-2 for information on what fuel to use in
cold weather.
