4RUNNER (1998)
The top portion of the label shows the
oil quality by API (American Petroleum
Institute) designations such as SJ.
The center portion of the label shows
the SAE
viscosity grade such as SAE 5W- 30.
ºEnergy- Conservingº shown in the
lower portion, indicates that the oil
has fuel- saving capab ilities.
The ILSAC (International Lubricant
Standardization and Approval Commit-
tee) Certification Mark is displayed on
the front of the container. Look at the see- through coolant
reservoir when the engine is cold.
The coolant level is satisfactory if
it is between the ºF (Full)º and ºL
(Low)º lines on the reservoir. If the
level is low, add ethylene- glycol
type coolant.
The coolant level in the reservoir will
vary with engine temperature. Howev-
er, if the level is on or below the ºLº
line, add coolant. Bring the level up
to the ºFº line.
Use only ethylene- glycol type coolant.
See information in the next column.
If the coolant level drops within a
short time after replenishing, there
may be a leak in the system. Visually
check the radiator, hoses, radiator cap
and drain cock and water pump.
If you can find no leak, have your
Toyota dealer test the cap pressure
and check for leaks in the cooling
system.
CAUTION
To prevent burning yourself, do
not remove the radiator cap when
the engine is hot.
Coolant type selection
Your coolant must contain ethylene-
glycol antifreeze. In addition to pre-
venting freezing and subsequent dam-
age to the engine, this will also
prevent corrosion. Further supplemen-
tal inhibitors or additives are neither
needed nor recommended.
Read the antifreeze container for in-
formation on freeze protection. Follow
the manufacturer 's directions for how
much to mix with water. The total ca-
pacity of the cooling system is given
in Part 8. We recommend 50% solu-
tion be used for your Toyota, or a
sufficient quantity to provide protection
to about -35
C (- 31 F).
NOTICE
Do not use alcohol type antifreeze
or plain water alone.
