Engine Coolant Heater - Buick 2009 Enclave Owner's Manual

2. If the engine does not start after
5-10 seconds, especially in
very cold weather (below 0°F
or −18°C), it could be flooded with
too much gasoline. Try pushing
the accelerator pedal all the way
to the floor and holding it there as
you hold the key in START for up
to a maximum of 15 seconds.
Wait at least 15 seconds between
each try, to allow the cranking
motor to cool down. When the
engine starts, let go of the key
and accelerator. If the vehicle
starts briefly but then stops again,
repeat these steps. This clears
the extra gasoline from the
engine. Do not race the engine
immediately after starting it.
Operate the engine and
transmission gently until the oil
warms up and lubricates all
moving parts.
Notice: The engine is designed
to work with the electronics
in the vehicle. If you add electrical
parts or accessories, you could
change the way the engine
operates. Before adding electrical
equipment, check with your
dealer/retailer. If you do not, the
engine might not perform
properly. Any resulting damage
would not be covered by the
vehicle warranty.

Engine Coolant Heater

The engine coolant heater can
provide easier starting and better
fuel economy during engine
warm-up in cold weather conditions
at or below 0°F (−18°C). Vehicles
with an engine coolant heater should
be plugged in at least four hours
before starting. Some models
may have an internal thermostat in
the cord which will prevent
engine coolant heater operation at
temperatures above 0°F (−18°C).
