2004 CADILLAC ESCALADE EXT coolant temperature

Engine Overheating
You will ®nd a coolant temperature gage on your
vehicle's instrument panel cluster. SeeEngine Coolant
Temperature Gage on page 3-42. In addition, you
will ®nd an ENGINE COOLANT HOT, ENGINE
OVERHEATED and a REDUCED ENGINE POWER
message in the DIC on the instrument panel. See
Driver
Information Center (DIC) on page 3-49.
Overheated Engine Protection
Operating Mode
If an overheated engine condition exists and the
REDUCED ENGINE POWER 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 your 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 and change the oil.
See
Engine Oil on page 5-11.
If Steam Is Coming From Your Engine
{CAUTION:
Steam from an overheated engine can burn
you badly, even if you just open the hood. Stay
away from the engine if you see or hear steam
coming from it. Just turn it off and get

problem. Have the system inspected and repaired and
the ¯uid level checked. Add ¯uid if needed.
Owner Checks and Services
These owner checks and services should be performed
at the intervals speci®ed to help ensure the safety,
dependability and emission control performance of your
vehicle. Your GM Goodwrench dealer can assist you

Whenever any ¯uids or lubricants are added to your
vehicle, make sure they are the proper ones, as shown
in
Recommended Fluids and Lubricants on page 6-13.

necessary. SeeEngine Oil on page 5-11for further
details.
