Cadillac Escalade Hybrid - 2011
10-12 Vehicle Care
1. Park the vehicle on a level
surface and turn the vehicle off.
Remove the DMCM coolant
surge tank pressure cap when
the DMCM cooling system,
including the DMCM coolant
surge 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.
