6B-6 ENGINE COOLING
MAINTENANCE
COOLANT LEVEL CHECK
To check level, lift hood and look at “see-through” coolant reser-
voir tank.
It is not necessary to remove radiator cap to check coolant level.
When engine is cool, check coolant level in reservoir tank (1).
A normal coolant level should be between FULL mark (2) and
LOW mark (3) on reservoir tank (1).
If coolant level is below LOW mark (3), remove reservoir tank cap
(4) and add proper coolant to tank to bring coolant level up to
FULL mark (2). Then, reinstall cap (4) and align match marks (5)
on tank and cap (4). WARNING:
Do not remove radiator cap to check engine coolant level; check coolant visually at the see-through
coolant reservoir.
Coolant should be added only to reservoir as necessary.
As long as there is pressure in the cooling system, the temperature can be considerably higher
than the boiling temperature of the solution in the radiator without causing the solution to boil.
Removal of the radiator cap while engine is hot and pressure is high will cause the solution to boil
instantaneously and possibly with explosive force, spewing the solution over engine, fenders and
person removing cap. If the solution contains flammable anti-freeze such as alcohol (not recom-
mended for use at any time), there is also the possibility of causing a serious fire.
WARNING:
To help avoid danger of being burned :
do not remove reservoir tank cap while coolant is boil-
ing, and
do not remove radiator cap while engine and radiator
are still hot.
Scalding fluid and steam can be blown out under pres-
sure if either cap is taken off too soon.
NOTE:
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.
When installing reservoir cap, align arrow marks on
reservoir and cap.
