Downloaded from www.Manualslib.com manuals search engine When the correct fluid level is obtained, push the dipstick back in all -
the way.
ENGINE COOLANT 7
The following explains your cooling system and how to add coolant when (. I
it is low. If you have a problem with engine overheating, see “Engine
Overheating” in the Index.
The proper coolant for your Cadillac will:
0 Give freezing protection down to -34°F (-37OC) .
0 Give boiling protection up to 262 F (128 C) .
0 Prote-ct against rust and corrosion.
Help keep the proper engine temperature.
Let the warning-lights work as they shoula.
What to Use
Use a mixture of one-half clean water (preferably distilled) and one-half
antifreeze 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. Use GM
Engine Coolant Supplement (sealer) with any complete coolant change.
If you use this mixture, you don’t need to add anything else.

A CAUTION:
brning the radiator pressure cap when the engine and radiator
are
hut 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.
A CAUTION:
You can be burned if you spil1 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.
I
NOTICE:
Your radiator pressure cap is a 15 psi (105 ma) pressure-type
cap and must be tightly installed to prevent coolant loss and
possible engine damage
from overheating. Be sure the arrows
on
the cap line up with the overflow tube on the radiator filier
neck.
When you replace your radiator pressure cap, a GM cap is
recommended.
