LIQUID GASKET APPLICATION PROCEDURE
NLLC0051
1.
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.)
+
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.

System Check
NLLC0054
WARNING:
Never remove the radiator cap when the engine is hot; serious
burns could be caused by high pressure fluid escaping from
the radiator.
Wrap a thick cloth around the cap and carefully remove it by
turning it a quarter turn to allow built-up pressure to escape
and then turn the cap all the way off.
CHECKING COOLING SYSTEM HOSES
NLLC0054S01
Check hoses for improper attachment, leaks, cracks, damage,
loose connections, chafing and deterioration.
CHECKING RADIATOR
NLLC0054S02
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.
1.
Apply water by hose to the back side of the radiator core ver-
tically downward.
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 downward.
+
Use compressed 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.
SLC755AC
CHECKING RADIATOR CAP
NLLC0054S03
To check radiator cap, apply pressure to cap with a tester.
Radiator cap relief pressure:
Standard
78 - 98 kPa
(0.78 - 0.98 bar, 0.8 - 1.0 kg/cm
2
, 11 - 14 psi)
Limit
59 - 98 kPa
(0.59 - 0.98 bar, 0.6 - 1.0 kg/cm
2
, 9 - 14 psi)
SMA967B
Pull the negative pressure valve to open it.
Check that it closes completely when released.
+
Check the radiator cap negative pressure valve for contamina-
tion or damage to the valve seat.
+
Move the negative pressure valve to check for abnormalities to
the opening/shutting operation.
CAUTION:
+
Be sure to perform the inspections after cooling down the
engine.
+
Before connecting the radiator cap to the tester, apply
water or LLC to the cap sealing.

+
Replace the radiator cap if abnormalities are found with the
negative pressure valve, or if the valve opening pressure is out
of the standard range.
SLC756AA
CHECKING COOLING SYSTEM FOR LEAKS
NLLC0054S04
To check for leakage, apply pressure to the cooling system with a
tester.
Testing pressure:
157 kPa (1.57 bar, 1.6 kg/cm
2
, 23 psi)
CAUTION:
+
Higher than the specified pressure may cause radiator
damage.
+
Be sure to perform the inspections after cooling down the
engine.
+
Use a hose adapter between the cap tester and filler neck
to prevent the radiator filler neck from deforming.
+
If any abnormalities are found, repair or replace the malfunc-
tioning parts.
Water Pump
REMOVAL AND INSTALLATION
NLLC0055
CAUTION:
+
When removing water pump assembly, be careful not to
get coolant on drive belt.
+
Water pump cannot be disassembled and should be
replaced as a unit.
+
After installing water pump, connect hose and clamp
securely, then check for leaks using radiator cap tester.
