LIQUID GASKET APPLICATION PROCEDURE

NLLC0001

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 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).

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.

Oil specification and viscosity (For Europe):

API grade SG, SH or SJ

ACEA grade A1-98, A3-98

ILSAC grade GF-I, GF-II
Refer to MA-20, “RECOMMENDED FLUIDS AND LUBRI-
CANTS”.

CAUTION:

Be sure to clean drain plug and install with new washer.

Drain plug:

: 29 - 39 N·m (3.0 - 4.0 kg-m, 22 - 29 ft-lb)

The refill capacity changes depending on the oil tempera-
ture and drain time, use these values as a reference and
be certain to check with the dipstick when changing the
oil.

WARNING:

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 RADIATOR

NLLC0017S04

Check 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, radiator shroud and horns.
Then tape the harness and connectors to prevent water from
entering.

Apply water by hose to the back side of the radiator core ver-
tically download.

Apply water again to all radiator core surfaces once per
minute.

Stop washing if any stains no longer flow out from the radia-
tor.

Blow air into the back side of radiator core vertically download.

Use compressed air lower than 490 kPa (4.9 bar, 5 kg/cm

, 71

psi) and keep distance more than 30 cm (11.8 in).

Blow air again into all the radiator core surfaces once per
minute until no water sprays out.

To check radiator cap, apply pressure to cap with a tester.

Radiator cap relief pressure:

Standard

78 - 98 kPa

, 11 - 14 psi)

Limit

59 - 98 kPa
(0.59 - 0.98 bar, 0.6 - 1.0 kg/cm
