See Battery - North America 0256.
Charging
This section explains the process
for charging the high voltage battery.
Do not allow the vehicle to remain in
temperature extremes for long
periods without being driven or
plugged in. It is recommended that the vehicle be plugged in when
temperatures are below 0 °C (32 °F)
and above 32 °C (90 °F) to
maximize high voltage battery life.
When using a 120-volt AC electrical
outlet, it will take approximately
13 hours to charge the vehicle with
the 12 amp AC current setting or
19 hours using the default 8 amp
AC current setting. When using a
240-volt charging station, it will take
approximately 4.5 hours to charge
the vehicle. Charge times will vary
with outside temperature. There are
three ways to program how the
vehicle is charged. See
Programmable Charging
0119.
The charging system may run fans
and pumps that result in sounds
from the vehicle while it is turned
off. Additional unexpected clicking
sounds may be caused by the
electrical devices used while
charging.
While the charge cord is plugged
into the vehicle, the vehicle cannot
be driven.

248 Vehicle Care
Cooling System (Engine)
1. Engine Cooling Fans (Outof View)
2. Engine Coolant Surge Tank and Pressure Cap
{Warning
The electric fans under the hood
can start up even when the
engine is not running and can
cause injury. Keep hands,
clothing, and tools away from any
underhood electric fan. If the coolant inside the coolant
surge tank is boiling, do not do
anything else until it cools down.
The vehicle should be parked on a
level surface.
The coolant level should be up to
the cold fill line. If it is not, there
might be a leak at the radiator
hoses, heater hoses, radiator, water
pump, or somewhere else in the
cooling system.
{Warning
Heater and radiator hoses, and
other engine parts, can be very
hot. Do not touch them. If you do,
you can be burned.
Do not run the vehicle if there is a
leak. If you run the engine, it
could lose all coolant. That could
cause an engine fire, and you
could be burned. Get any leak
fixed before you drive the vehicle.
If there seems to be no leak, with
the engine on, check to see if the
cooling fans are running. If the
engine is overheating, the fans should be running. If it is not, the
vehicle needs service. Turn off the
vehicle.
Cooling System (High
Voltage Battery)
During vehicle operation and also
during charging, the high voltage
battery cells in the vehicle are kept
within a normal operating
temperature range. If the high
voltage battery cell temperature
rises above the normal operating
temperature range, the battery
cooling system turns on the air
conditioning compressor and cools
the coolant until the correct battery
cell temperature is reached. If the
high voltage battery cell temperature
falls below the normal operating
temperature range, a high voltage
heater, located in the battery, heats
the coolant until the correct battery
cell temperature is reached.
During high voltage battery system
cooling, you may feel temperature
changes at the air vents due to the
extra load on the system.

9807421) - 2017 - CRC - 11/18/15
250 Vehicle Care
The coolant needs to be replaced at
the appropriate interval. See
Maintenance Schedule0326.
Checking Coolant
The vehicle must be on a level
surface when checking the coolant
level.
The power electronics and charger
modules coolant reservoir is located
in the engine compartment. See
Engine Compartment
Overview 0242.
1. High Voltage Battery
Coolant Reservoir 2. Power Electronics Coolant
Reservoir
Check to see if coolant is visible in
the power electronics coolant
reservoir (2). If coolant is visible but
the coolant level is below the cold
fill line on the side of the reservoir,
there could be a leak in the cooling
system.
The power electronics cooling
system supports the operation of
sensitive electronics.
The power electronics cooling
system should only be serviced by a
qualified technician.
Engine Coolant
The engine cooling system in the
vehicle is filled with GM Premix
DEX-COOL engine coolant. See
Recommended Fluids and
Lubricants 0334. The coolant
requires changing at certain
intervals. See Maintenance
Schedule 0326. The following explains the cooling
system and how to check and add
coolant when it is low. If there is a
problem with engine overheating,
see
Engine Overheating 0253.
What to Use
{Warning
Adding only plain water or some
other liquid to the cooling system
can be dangerous. Plain water
and other liquids, can boil before
the proper coolant mixture will.
The coolant warning system is set
for the proper coolant mixture.
With plain water or the wrong
mixture, the engine could get too
hot but you would not get the
overheat warning. The engine
could catch fire and you or others
could be burned. Use GM Premix
DEX-COOL coolant.

Chevrolet VOLT Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
9807421) - 2017 - CRC - 11/18/15
Vehicle Care 251
Use GM Premix DEX-COOL engine
coolant. If using this mixture,
nothing else needs to be added.
This mixture:
.Gives freezing protection down
to−37 °C (−34 °F), outside
temperature.
. Gives boiling protection up to
129 °C (265 °F), engine
temperature.
. Protects against rust and
corrosion.
. Will not damage aluminum parts.
. Helps keep the proper engine
temperature.
Caution
If improper coolant mixture,
inhibitors, or additives are used in
the vehicle cooling system, the
engine could overheat and be
damaged. Too much deionized
water or clean drinkable water
can freeze and crack engine
cooling parts. The repairs would
(Continued)
Caution (Continued)
not be covered by the vehicle
warranty. Use only the proper
mixture of engine coolant for the
cooling system. See
Recommended Fluids and
Lubricants0334.
Never dispose of engine coolant by
putting it in the trash, pouring it on
the ground, or into sewers, streams,
or bodies of water. Have the coolant
changed by an authorized service
center, familiar with legal
requirements regarding used
coolant disposal. This will help
protect the environment and your
health.
Checking Coolant
The vehicle must be on a level
surface when checking the coolant
level.
Check to see if coolant is visible in
the coolant surge tank. If the coolant
inside the coolant surge tank is
boiling, do not do anything else until
it cools down. If coolant is visible but the coolant level is not at or
above the cold fill mark, add GM
Premix DEX-COOL engine coolant
at the coolant surge tank, but be
sure the cooling system is cool
before this is done. See
Engine
Overheating 0253.
The coolant reservoir is on the
passenger side of the engine
compartment. See Engine
Compartment Overview 0242.
The coolant level should be at or
above the cold fill line on the
coolant surge tank. If it is not, there
could be a leak in the cooling
system.
How to Add Coolant to the
Coolant Surge Tank
{Warning
You can be burned if you spill
coolant on hot engine parts.
Coolant contains ethylene glycol
and it will burn if the engine parts
are hot enough. Do not spill
coolant on a hot engine.

Caution
If the pressure cap is not tightly
installed, coolant loss and
possible engine damage may
occur. Be sure the cap is properly
and tightly secured.
Engine Overheating
The vehicle has an indicator to warn
of engine overheating.
If the decision is made not to lift the
hood when this warning appears,
get service help right away. See
Roadside Assistance
Program0345.
If the decision is made to lift the
hood, make sure the vehicle is
parked on a level surface.
Then check to see if the engine
cooling fan is running. If the engine
is overheating, the fan should be
running. If it is not, do not continue
to run the vehicle, and have the
vehicle serviced.
Caution
Running the engine without
coolant may cause damage or a
fire. Vehicle damage would not be
covered by the vehicle warranty.
Washer Fluid
What to Use
When adding windshield washer
fluid to the vehicle, be sure to read
the manufacturer's instructions
before use. If operating the vehicle
in an area where the temperature
may fall below freezing, use a fluid
that has sufficient protection against
freezing.
Adding Washer Fluid
Open the cap with the washer
symbol on it. Add washer fluid until
the tank is full. See Engine
Compartment Overview 0242 for
reservoir location.
Caution
. Do not use washer fluid that
contains any type of water
repellent coating. This can
cause the wiper blades to
chatter or skip.
. Do not use engine coolant
(antifreeze) in the
windshield washer. It can
damage the windshield
washer system and paint.
. Do not mix water with
ready-to-use washer fluid.
