Precautions
LIQUID GASKET APPLICATION PROCEDURENJLC00141. 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 3.5 to 4.5 mm
(0.138 to 0.177 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.

System CheckNJLC0017WARNING:
Never remove the radiator cap when the engine is hot. Serious
burns could occur from high pressure fluid escaping from the
radiator.
Wrap a thick cloth around the cap. Slowly turn it a quarter turn
to allow built-up pressure to escape. Carefully remove the cap
by turning it all the way.

CHECKING RADIATORNJLC0017S04Check radiator for mud or clogging. If necessary, clean radiator as
follows.
Be careful not to bend or damage the radiator fins.
When radiator is cleaned without removal, remove all sur-
rounding parts such as cooling fan, rediator shroud and horns.
Then tape the harness and connectors to prevent water from
entering.
1. Apply water by hose to the back side of the radiator core ver-
tically download.
2. Apply water again to all radiator core surfaces once per
minute.
3. Stop washing if any stains no longer flow out from the radia-
tor.
4. Blow air into the back side of radiator core vertically download.
Use compressesd air lower than 490 kPa (4.9 bar, 5 kg/cm
2,
71 psi) and keep distance more than 30 cm (11.8 in).
5. Blow air again into all the radiator core surfaces once per
minute until no water sprays out.

CHECKING RADIATOR CAPNJLC0017S03To check radiator cap, apply pressure to cap with a tester.
Radiator cap relief pressure:

Pull the negative pressure valve to open it.
Check that it closes completely when released.

CHECKING COOLING SYSTEM FOR LEAKSNJLC0017S02To check for leakage, apply pressure to the cooling system with a
tester.
Testing pressure:
157 kPa (1.57 bar, 1.6 kg/cm2,23psi)
CAUTION:
Higher pressure than specified may cause radiator damage.
