Chevrolet 2006 Epica, Owner'S Manual

Page: 244 / 368

What to Use
Use a 50/50 mixture of clean, drinkable water and
coolant that meets GM specification 1825M, which will
not damage aluminum parts. You can also use a recycled
coolant conforming to GM specification 1825M with a
complete coolant flush and refill. 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 the proper
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 four times a year,
have your dealer 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
Part D: Recommended
Fluids and Lubricants on page 6-25 for more
information.
