To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord. On a
vehicle with a 2.2L L4 (LN2) engine, the electrical
cord is located near the engine oil dipstick. On a
vehicle with a 2.4L L4 (LD9) or 2.2L L4 ECOTEC
(L61) engine, the electrical cord is located in front of
the coolant surge tank on the passenger’s side.
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 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 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.
