engine coolant CADILLAC ESCALADE ESV 2009 Owner's Manual

If No Steam Is Coming From The
Engine Compartment The ENGINE OVERHEATED STOP ENGINE or the
ENGINE OVERHEATED IDLE ENGINE message, along
with a low coolant condition, can indicate a serious
problem.
If you get an engine overheat warning, but see or
hear no steam, the problem may not be too serious.
Sometimes the engine can get a little too hot when you:
Climb a long hill on a hot day.
Stop after high-speed driving.
Idle for long periods in traffic.
Tow a trailer. See Towing a Trailer on page 5-44 .
If you get the ENGINE OVERHEATED STOP ENGINE or
the ENGINE OVERHEATED IDLE ENGINE message
with no sign of steam, try this for a minute or so:
If the overheat warning is displayed with no sign of
steam:
1. Turn the air conditioning off.
2. Turn the heater on to the highest temperature and
to the highest fan speed. Open the windows as
necessary. 3. In heavy traffic, let the engine idle in N (Neutral)
while stopped. If it is safe to do so, pull off the
road, shift to P (Park) or N (Neutral) and let
the engine idle.
If the temperature overheat gage is no longer in the
overheat zone or an overheat warning no longer displays,
the vehicle can be driven. Continue to drive the vehicle
slow for about 10 minutes. Keep a safe vehicle distance
from the car in front of you. If the warning does not come
back on, continue to drive normally.
If the warning continues, pull over, stop, and park the
vehicle right away.
If there is no sign of steam, idle the engine for
ve minutes while parked. If the warning is still
displayed, turn off the engine until it cools down.
Also, see “Overheated Engine Protection Operating
Mode” later in this section.

Overheated Engine Protection
Operating Mode If an overheated engine condition exists and the
ENGINE POWER IS REDUCED message is displayed,
an overheat protection mode which alternates ring
groups of cylinders helps prevent engine damage.
In this mode, you will notice a loss in power and engine
performance. This operating mode allows the vehicle
to be driven to a safe place in an emergency. Driving
extended miles (km) and/or towing a trailer in the
overheat protection mode should be avoided.
Notice: After driving in the overheated engine
protection operating mode, to avoid engine damage,
allow the engine to cool before attempting any repair.
The engine oil will be severely degraded. Repair the
cause of coolant loss, change the oil and reset the oil
life system. See Engine Oil on page 6-15 .Engine Fan Noise The vehicle has electric cooling fans. You might hear
the fans spinning at low speed during most everyday
driving. The fans can turn off if no cooling is required.
Under heavy vehicle loading, trailer towing, and/or
high outside temperatures, or if you are operating the
air conditioning system, the fans can change to
high speed and you might hear an increase in fan noise.
This is normal and indicates that the cooling system
is functioning properly. The fans change to low speed
when additional cooling is no longer required.
Power Steering Fluid See Engine Compartment
Overview on page 6-14 for
reservoir location.
6-33

Adding Washer Fluid The vehicle has a low washer uid message in the DIC
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 WASHER FLUID LOW ADD FLUID
message displays, you will need to add washer uid to
the windshield washer uid reservoir.
Open the cap with the
washer symbol on it.
Add washer uid until the
tank is full. See Engine
Compartment Overview on
page 6-14 for reservoir
location. Notice:
When using concentrated washer uid, follow
the manufacturer’s instructions for adding
water.
Do not 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 does not
clean as well as washer uid.
Fill the washer uid tank only three-quarters
full when it is very cold. This allows for uid
expansion if freezing occurs, which could
damage the tank if it is completely full.
Do not use engine coolant (antifreeze) in your
windshield washer. It can damage the vehicle’s
windshield washer system and paint.

When the CHANGE ENGINE OIL SOON message
appears, the following services, checks, and inspections
are required:
❑ Change engine oil and lter. See Engine Oil on
page 6-15 . Reset oil life system. See Engine
Oil Life System on page 6-18 . An Emission
Control Service.
❑ Lubricate chassis components. See footnote #.
❑ Visually check for any leaks or damage.
See footnote (j).
❑ Inspect engine air cleaner lter or change indicator
(if equipped). If necessary, replace lter. See Engine
Air Cleaner/Filter on page 6-19 . See footnote (k).
❑ Rotate tires and check ination pressures and wear.
See Tire Inspection and Rotation on page 6-69 and
“Tire Wear Inspection” in At Least Once a Month on
page 7-10 . ❑ Inspect brake system. See footnote (a).
❑ Check engine coolant and windshield washer uid
levels and add uid as needed.
❑ Perform any needed additional services.
See “Additional Required Services” in this section.
❑ Inspect suspension and steering components.
See footnote (b).
❑ Inspect engine cooling system. See footnote (c).
❑ Inspect wiper blades. See footnote (d).
❑ Inspect restraint system components.
See footnote (e).
❑ Lubricate body components. See footnote (f).
❑ Check transmission uid level and add uid as
needed.

(f) Lubricate all key lock cylinders, hood latch assembly,
secondary latch, pivots, spring anchor, release pawl, rear
compartment hinges, outer tailgate handle pivot points,
latch bolt, fuel door hinge, and folding seat hardware.
More frequent lubrication may be required when exposed
to a corrosive environment. Applying silicone grease on
weatherstrips with a clean cloth will make them last
longer, seal better, and not stick or squeak.
(g) Inspect system. Check all fuel and vapor lines
and hoses for proper hook-up, routing, and condition.
Check that the purge valve works properly, if equipped.
Replace as needed.
(h) Change automatic transmission fluid and filter if the
vehicle is mainly driven under one or more of these
conditions:
In heavy city traffic where the outside temperature
regularly reaches 90°F (32°C) or higher.
In hilly or mountainous terrain.
When doing frequent trailer towing.
Uses such as found in taxi, police, or delivery
service.
(i) Drain, flush, and refill cooling system. This service
can be complex; you should have your dealer/retailer
perform this service. See Engine Coolant on page 6-25
for what to use. Inspect hoses. Clean radiator,
condenser, pressure cap, and filler neck. Pressure
test the cooling system and pressure cap. (j) A fluid loss in any vehicle system could indicate a
problem. Have the system inspected and repaired and
the fluid level checked. Add fluid if needed.
(k) If driving regularly under dusty conditions, inspect
the filter at each engine oil change.
(l) Visually inspect belt for fraying, excessive cracks, or
obvious damage. Replace belt if necessary.
(m) Check vent hose at transfer case for kinks and
proper installation. Check to be sure vent hose is
unobstructed, clear, and free of debris. During any
maintenance, if a power washer is used to clean mud
and dirt from the underbody, care should be taken to
not directly spray the transfer case output seals.
High pressure water can overcome the seals and
contaminate the transfer case fluid. Contaminated fluid
will decrease the life of the transfer case and should
be replaced.
(n) Severe Service: Change transfer case fluid if the
vehicle is mainly used for trailer towing or driven in city
traffic, wet environment, or high ambient temperatures.

Owner Checks and Services These owner checks and services should be performed
at the intervals specied to help ensure vehicle
safety, dependability, and emission control performance.
Your dealer/retailer can assist with these checks and
services.
Be sure any necessary repairs are completed at once.
Whenever any uids or lubricants are added to the
vehicle, make sure they are the proper ones, as shown
in Recommended Fluids and Lubricants on page 7-13 .
At Each Fuel Fill It is important to perform these underhood checks at
each fuel fill.
Engine Oil Level Check Notice: It is important to check the engine oil
regularly and keep it at the proper level. Failure to
keep the engine oil at the proper level can cause
damage to the engine not covered by the vehicle
warranty.
Check the engine oil level and add the proper oil if
necessary. See Engine Oil on page 6-15 . Engine Coolant Level Check Check the engine coolant level and add DEX-COOL ®
coolant mixture if necessary. See Engine Coolant
on page 6-25 .
Windshield Washer Fluid Level Check Check the windshield washer uid level in the
windshield washer uid reservoir and add the proper
uid if necessary.
At Least Once a Month
Tire Ination Check Inspect the vehicle’s tires and make sure they are
inated to the correct pressures. Do not forget to check
the spare tire, if the vehicle has one. See Inflation - Tire
Pressure on page 6-62 . If the vehicle has a spare tire,
check to make sure it is stored securely. See Changing
a Flat Tire on page 6-78 .
Tire Wear Inspection Tire rotation may be required for high mileage highway
drivers prior to the Engine Oil Life System service
notication. Check the tires for wear and, if necessary,
rotate the tires. See Tire Inspection and Rotation on
page 6-69 .
