Caution
Do not use anything other than a
pre-mix of DEX-COOL coolant
that meets GM Standard
GMW3420 and deionized water.
Anything else can cause damage
to the hybrid cooling system
components and the vehicle,
which would not be covered by
the vehicle warranty.
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 line, add GM
Premix DEX-COOL engine coolant.
Be sure the cooling system is cool
before this is done. See Engine
Overheating 0 253.
The coolant surge tank is on the
driver side of the engine
compartment. See Engine
Compartment Overview 0 241.
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
Spilling coolant on hot engine
parts can burn you. Coolant
contains ethylene glycol and it will
burn if the engine parts are hot
enough.
