engine.
6.

Stop engine and cool it down.

Cool down using a fan to reduce the time.

If necessary, refill radiator up to filler neck with coolant.

Refill reservoir tank to Max line with coolant.

Repeat step 5 through step 7 two or more times with radiator
cap installed until coolant level no longer drops.

Check cooling system for leaks with engine running.

10. Warm up engine, and check for sound of coolant flow while

running engine from idle up to 3,000 rpm with heater tempera-
ture controller set at several positions between COOL and
HOT.

Sound may be noticeable at heater water cock.

11. If sound is heard, bleed air from cooling system by repeating

steps 5 through 7 until coolant level no longer drops

Clean excess coolant from engine.

LIQUID GASKET APPLICATION PROCEDURE

NLLC0039

Use a scraper to remove all traces of old liquid gasket from
mating surfaces and grooves. Also, completely clean any oil
from these areas.

Apply a continuous bead of liquid gasket to mating surfaces.
(Use Genuine Liquid Gasket or equivalent.)

For oil pan, be sure liquid gasket diameter is 4.0 to 5.0 mm
(0.157 to 0.197 in).

For areas except oil pan, be sure liquid gasket diameter is 2.0
to 3.0 mm (0.079 to 0.118 in).

Apply liquid gasket around the inner side of bolt holes (unless
otherwise specified).

Assembly should be done within 5 minutes after coating.

Wait at least 30 minutes before refilling engine oil and engine
coolant.

WARNING:

Be careful not to burn yourself, as the engine oil is hot.

Prolonged and repeated contact with used engine oil may
cause skin cancer; try to avoid direct skin contact with
used oil. If skin contact is made, wash thoroughly with
soap or hand cleaner as soon as possible.

Warm up engine, and check for oil leakage from engine com-
ponents.

Stop engine and wait more than 10 minutes.

Remove drain plug and oil filler cap.

Drain oil and refill with new engine oil.
