Cadillac 2008 SRX - Manual (Page 310)

Adding Coolant
If more coolant is needed, add the proper DEX-COOL ®
coolant mixture at the surge tank, but only when the
engine is cool.
{ 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.
When replacing the pressure cap, make sure it is
hand-tight and fully seated.
Coolant Surge Tank Pressure Cap
Notice: If the pressure cap is not tightly installed,
coolant loss and possible engine damage may
occur. Be sure the cap is properly and tightly
secured.
The coolant surge tank pressure cap must be fully
installed on the coolant surge tank. See Engine
Compartment Overview on page 5-12 for more
information on location.
Engine Overheating
There are two engine hot messages that could be
displayed in the Driver Information Center (DIC).
See DIC Warnings and Messages on page 3-53 for
more information.
If the engine is overheating, then you will find a coolant
temperature gage and a coolant warning light on the
instrument panel. See Engine Coolant Temperature
Gage on page 3-40 and Engine Coolant Temperature
Warning Light on page 3-40 for more information.
