Buick 2009 Enclave - Manual (Page 291)

Notice: If extra inhibitors and/or
additives are used in the
vehicle’s cooling system, the
vehicle could be damaged. Use
only the proper mixture of
the engine coolant listed in this
manual for the cooling system.
See Recommended Fluids
and Lubricants on page 6-11 for
more information.
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 recovery tank. If the
coolant inside the coolant recovery
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 FULL COLD
mark, add a 50/50 mixture of clean,
drinkable water and DEX-COOL
coolant at the coolant recovery tank,
but be sure the cooling system is
cool before this is done. See Engine
Coolant on page 5-18 for more
information.
The coolant recovery tank cap has
this symbol on it.
When the engine is cold, the
coolant level should be at or above
the FULL COLD line marked on
the recovery tank.
When the engine is hot, the level
could be higher than the FULL
COLD line. If the coolant is below
the FULL COLD line when the
engine is hot, there could be a leak
in the cooling system.
If the coolant is low, add the
coolant or take the vehicle to a
dealer/retailer for service.
How to Add Coolant to the
Recovery Tank
{ CAUTION
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.
Notice: This vehicle has a
specific coolant fill procedure.
Failure to follow this procedure
could cause the engine to
overheat and be severely
damaged.
If coolant is needed, add the proper
DEX-COOL
® coolant mixture at
the coolant recovery tank.
