Engine Coolant - Cadillac 2015 SRX Owner's Manual

Caution
Using coolant other than
®
DEX-COOL can cause
premature engine, heater core,
or radiator corrosion. In addition,
the engine coolant could require
changing sooner. Any repairs
would not be covered by the
vehicle warranty. Always use
DEX-COOL (silicate-free) coolant
in the vehicle.

Engine Coolant

The cooling system in the vehicle is
®
filled with DEX-COOL
coolant. This coolant needs to be
checked and replaced at
appropriate intervals. See
Scheduled Maintenance on
page 11-1.
The following explains the cooling
system and how to check and add
coolant when it is low. If there is a
problem with engine overheating,
see Engine Overheating on
page 10-16.
What to Use
Adding only plain water or some
other liquid to the cooling system
can be dangerous. Plain water
and other liquids, can boil before
the proper coolant mixture will.
The coolant warning system is set
for the proper coolant mixture.
With plain water or the wrong
mixture, the engine could get too
hot but you would not get the
engine
overheat warning. The engine
could catch fire and you or others
could be burned. Use a 50/
50 mixture of clean, drinkable
water and DEX-COOL coolant.
