What To Use - Cadillac 2008 SRX Owner's Manual

What to Use

Use a mixture of one-half clean, drinkable water and
®
one-half DEX-COOL coolant which will not damage
aluminum parts. If you use this coolant mixture, you do
not need to add anything else.
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
would not get the overheat warning. Your
engine could catch fire and you or others could
be burned. Use a 50/50 mixture of clean,
drinkable water and DEX-COOL
5-24
®
coolant.
Notice: If you use an improper coolant mixture, your
engine could overheat and be badly damaged. The
repair cost would not be covered by your warranty.
Too much water in the mixture can freeze and crack
the engine, radiator, heater core, and other parts.
If you have to add coolant more than once or twice a
year, have your dealer/retailer check your cooling
system.
Notice: If you use extra inhibitors and/or additives in
your vehicle's cooling system, you could damage
your vehicle. Use only the proper mixture of the
engine coolant listed in this manual for the cooling
system. See Recommended Fluids and Lubricants on
page 6-12 for more information.
