How to Check and Add Fluid
You do not need to check the fluid level unless you
suspect a clutch problem. To check the fluid level, look
at the markings on the reservoir. If the fluid reaches
the MAX line, the fluid level is correct.
Engine Coolant
The following explains your cooling system and how to
add coolant when it is low. If you have a problem
with engine overheating, see
Engine Overheating on
page 5-28
.
A 50/50 mixture of clean, drinkable water and the proper
coolant will:
• Give freezing protection down to −33°F (−36°C)
• Give boiling protection up to 258°F (125°C).
• Protect against rust and corrosion.
• Help keep the proper engine temperature.
• Let the warning lights and gages work as they
should.
What to Use
Use a 50/50 mixture of
clean, drinkable water
and
coolant that meets GM Specification 1825-M, which
won’t damage aluminum parts. You can also use
a recycled coolant conforming to GM
Specification 1825-M with a complete coolant flush and
refill. If you use this coolant mixture, you don’t 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.
