MAINTENANCE
COOLANT LEVEL CHECK
WARNING:
To help avoid danger of being burned:
Do not remove reservoir cap while coolant is “boiling”,
and
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.
To check level, lift hood and look at “see-through” coolant reservoir.
It is not necessary to remove radiator cap to check coolant level.
When engine is cool, check coolant level in reservoir.
A normal coolant level should be between “FULL” and “LOW”
marks on reservoir.
If coolant level is below “LOW” mark, remove reservoir cap and add
proper coolant to reservoir to bring coolant level up to “FULL” mark.
Then, reinstall cap.
NOTE:
If recommended quality antifreeze is used, there is no need
to add extra inhibitors or additives that claim to improve sys-
tem.
They may be harmful to proper operation of system.
When installing reservoir cap, align arrow marks on reser-
voir and cap.
