engine coolant CADILLAC ESCALADE EXT 2003 2.G Owner's Manual

{CAUTION:
Adding only plain water to your cooling
system can be dangerous. Plain water, or
some other liquid such as alcohol, can boil
before the proper coolant mixture will. Your
vehicle's coolant warning system is set for the
proper coolant mixture. With plain water or the
wrong mixture, your engine could get too hot
but you wouldn't get the overheat warning.
Your engine could catch ®re and you or others
could be burned. Use a 50/50 mixture of clean,
drinkable water and DEX-COOL
žcoolant.
Notice:In cold weather, water can freeze and crack
the engine, radiator, heater core and other parts.
Use the recommended coolant and the proper
coolant mixture.
{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. Don't spill coolant on a hot engine.

3. Then ®ll the coolant surge tank with the proper
mixture, to the FULL COLD mark.4. With the coolant surge tank pressure cap off, start
the engine and let it run until you can feel the upper
radiator hose getting hot. Watch out for the
engine cooling fan.
By this time, the coolant level inside the coolant
surge tank may be lower. If the level is lower, add
more of the proper mixture to the coolant surge tank
until the level reaches the FULL COLD mark.

Windshield Washer Fluid
What to Use
When you need windshield washer ¯uid, be sure to read
the manufacturer's instructions before use. If you will
be operating your vehicle in an area where the
temperature may fall below freezing, use a ¯uid that has
sufficient protection against freezing. See
Engine
Compartment Overview on page 5-12for reservoir
location.
Adding Washer Fluid
Your vehicle has a low washer ¯uid message that
comes on when the washer ¯uid is low. The message is
displayed for 15 seconds at the start of each ignition
cycle. When the LOW WASHER FLUID message
is displayed, you will need to add washer ¯uid to the
windshield washer ¯uid reservoir.
The windshield washer
¯uid reservoir is located in
the engine compartment
toward the front of the
vehicle on the driver's side.Open the cap with the washer symbol on it. Add washer
¯uid until the tank is full.
Notice:
·When using concentrated washer ¯uid, follow
the manufacturer's instructions for adding
water.
·Don't mix water with ready-to-use washer ¯uid.
Water can cause the solution to freeze and
damage your washer ¯uid tank and other parts
of the washer system. Also, water doesn't
clean as well as washer ¯uid.
·Fill your washer ¯uid tank only three-quarters
full when it's very cold. This allows for
expansion if freezing occurs, which could
damage the tank if it is completely full.
·Don't use engine coolant (antifreeze) in your
windshield washer. It can damage your
washer system and paint.
