MAINTENANCE
COOLANT LEVEL CHECK
Coolant Level
To check level, lift hood and look at "see-through" coolant reservoir
(1).
It is not necessary to remove radiator cap to check coolant level.
WARNING:
To help avoid danger of being burned:
D Do not remove reservoir cap while coolant is "boiling".
D Do not remove radiator cap while engine and radiator are
still hot.
Scalding fluid and steam can be blown out under pressure
if either cap is taken off too soon.
When engine is cool, check coolant level in reservoir.
A normal coolant level should be between "FULL" (3) and "LOW"
(4) level marks on reservoir.
If coolant level is below "LOW" level mark, remove reservoir cap (2)
and add proper coolant to reservoir to bring coolant level up to
"FULL" level mark. Then, reinstall cap and align match marks on
tank and cap.
NOTE:
D If proper quality antifreeze is used, there is no need to add
extra inhibitors or additives that claim to improve system.
They may be harmful to proper operation of system, and are
unnecessary expense.
D When installing reservoir cap, align arrow marks on reser-
voir and cap.
