Checking Coolant - Chevrolet 2009 Equinox Owner's Manual

Notice: If an improper coolant mixture is used,
the engine could overheat and be badly damaged.
The repair cost would not be covered by the vehicle
warranty. Too much water in the mixture can freeze
and crack the engine, radiator, heater core, and
other parts.
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 6-13 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 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 a 50/50 mixture
of clean, drinkable water and DEX-COOL
the coolant surge tank, but be sure the cooling system
is cool before this is done.
The surge tank is located on the driver's side of the
engine compartment. See Engine Compartment
Overview on page 5-12 for more information on location.
When your engine is cold, the coolant level should be
at the COLD FILL line. When your engine is warm,
the level should be at the COLD FILL line or a
little higher.
The coolant level should be at the COLD FILL line.
If it is not, you may have a leak in the cooling system.
