+Pour coolant through coolant filler neck slowly to allow air
in system to escape.
3. Fill radiator and reservoir tank to specified level.
4. Warm up engine to normal operating temperature without
radiator cap installed.
+If coolant overflows radiator filler hole, install filler cap.
5. Run engine at 2,500 rpm for 10 seconds and return to idle
speed with radiator cap installed.
+Repeat two or three times.
Watch coolant temperature gauge so as not to overheat the
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.
7. Refill reservoir tank to MAX level line with coolant.
8. Repeat steps 4 through 7 two or more times with radiator cap
installed until coolant level no longer drops.
9. 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 4 through 7 until coolant level no longer drops
+Clean excess coolant from engine.
Ð FLUSHING COOLING SYSTEM ÐNJLC0037S031. Open air relief plug.
2. Fill radiator with water until water spills from the air relief hole,
then close air relief plug. Fill radiator and reservoir tank with
water and reinstall radiator cap.
3. Run engine and warm it up to normal operating temperature.
4. Rev engine two or three times under no-load.
5. Stop engine and wait until it cools down.
6. Drain water.
7. Repeat steps 1 through 6 until clear water begins to drain from
radiator.

Precautions
LIQUID GASKET APPLICATION PROCEDURENJLC00391. Use a scraper to remove all traces of old liquid gasket from
mating surfaces and grooves. Also, completely clean any oil
from these areas.
2. 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).
3. Apply liquid gasket around the inner side of bolt holes (unless
otherwise specified).
4. Assembly should be done within 5 minutes after coating.
5. Wait at least 30 minutes before refilling engine oil and engine
coolant.
