Black plate (11,1)Cadillac Escalade Hybrid - 2012
Vehicle Care 10-11surge tank pressure cap and
DMCM cooling hoses, are no
longer hot. Turn the DMCM
coolant surge tank pressure cap
slowly counterclockwise (left)
about one full turn. Wait
30 seconds.
2. Then keep turning the DMCM
coolant surge tank pressure cap
slowly, and remove it.
3. Add the pre ‐ mixed DEX ‐ COOL,
available at your dealer, to the
DMCM coolant surge tank until
the level reaches the FULL
COLD mark. 4. Turn the ignition to ON/RUN
without starting the engine. The
hybrid cooling pumps will run
and any trapped air will purge to
the surge tank.
5. Add the pre ‐ mixed DEX ‐ COOL,
available at your dealer, until the
coolant level is maintained at the
FULL COLD mark. This should
take no longer than two minutes
of hybrid cooling pump
operation.
If the level cannot be kept at the
FULL COLD level, the vehicle
may need service. See your
dealer.
6. Then replace the DMCM coolant
surge tank pressure cap. Be
sure the pressure cap is
hand-tight and fully seated. Notice: Using tap water, cooling
system sealers or conditioners in
an attempt to stop coolant leaks
can damage the DMCM and
engine cooling systems. Never
use tap water, cooling system
sealers or conditioners in your
cooling system.
Battery This vehicle has a standard 12 ‐ volt
battery and a high voltage hybrid
battery.
Refer to the replacement number on
the original battery label when a
new standard 12 ‐ volt battery is
needed.
Only a trained service technician
with the proper knowledge and
tools should inspect, test, or replace
the hybrid battery. See your dealer
if the hybrid battery needs service.
The dealer has information on how
to recycle the hybrid battery. There
is also information available at
