What to Use:
Use a mixture of clean water (preferably distilled) and antifreeze that meets
“GM Specification 6038-M,” which won’t damage aluminum parts. Also use

a complete coolant change. If
you use these, you don’t need to add anything else.

for the proper coolant mix. With plain water or the wrong mix, your
engine could get

To Check Coolant: When your engine is cold, the coolant level should be at
ADD, or a little higher. When your engine is warm, the level should be up to
FULL HOT, or a little higher.
To Add Coolant: If you need more coolant, add the proper mix at the
coolant recovery tank.
A
Turning the radiator pressure cap when the engine and radiator \
are
hot can allow steam and scalding liquids to blow out and burn you
badly. With the coolant recovery tank, you will almost never have to
add coolant at the radiator. Never turn the radiator pressure
cap-even a little-when the engine and radiator are hot.
Add coolant mix at the recovery tank, but be careful not to spill\
it.

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. Don’t spill coolant on a hot engine.

So, it isn’t a good idea to “top off” your brake fluid. Adding brake fluid won’t
correct a leak.
If you add fluid when your linings are worn, then you’ll have \
too much fluid when you get new brake linings. You should add (or remove)
brake fluid, as necessary, only when work is done on the brake hydraulic
system.
If you have too much brake fluid,
it can spill on the engine. The fluid
will burn if the engine is hot enough. You or others could be burned,
and your vehicle could be damaged. Add brake fluid only when work
is done on the brake hydraulic system. I
Refer to the Maintenance Schedule to determine when to check your brake
fluid. See “Periodic Maintenance Inspections” in the Index.
