To Use The Engine Coolant Heater - Pontiac 2008 Grand Prix Owner's Manual

To Use the Engine Coolant Heater

1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The cord is located above the engine air
cleaner/filter. See Engine Compartment
Overview on page 5-12 for more information
on location.
3. Plug the cord 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, making sure to
keep it away from moving engine parts. If this is
not done, the cord could be damaged.
How long should the coolant heater be kept plugged in?
The answer depends on the outside temperature, the
kind of oil that is in the vehicle, and some other things.
Instead of trying to list everything here, we ask that
you contact your dealer/retailer in the area where the
vehicle will be parked. The dealer/retailer can give
you the best advice for that particular area.
