To Check Coolant:
When your engine is cold, the
coolant level should be at "FULL COLD,'' 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
CAUTION:
Turning the radiator pressure cap when the
engine and radiator are hot can allow steam and
scaldlng 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.
