Liquid Gasket Application Procedure
a. Use a scraper to remove all traces of old liquid gasket frommating surfaces and grooves. Also, completely clean any oil
from these areas.
b. Apply a continuous bead of liquid gasket to mating surfaces. (Use Genuine Liquid Gasket or equivalent.)
IFor oil pan, be sure liquid gasket diameter is 3.5 to 4.5 mm
(0.138 to 0.177 in).
I For areas except oil pan, be sure liquid gasket diameter is
2.0 to 3.0 mm (0.079 to 0.118 in).
c. Apply liquid gasket around the inner side of bolt holes (unless otherwise specified).
d. Assembly should be done within 5 minutes after coating.
e. Wait at least 30 minutes before refilling engine oil and engine coolant.

PRECAUTIONS AND PREPARATIONZD
LC-2
http://vnx.su/

System Check
WARNING:
Never remove the radiator cap when the engine is hot. Serious
burns could occur from high pressure coolant 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 COOLING SYSTEM HOSES
Check hoses for the following:
IImproper attachment
I Leaks
I Cracks
I Damage
I Chafing
I Deterioration
CHECKING COOLING SYSTEM FOR LEAKS
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 pressure than specified may cause radiator damage.
CHECKING RADIATOR CAP
To check radiator cap, apply pressure to cap with a tester. Radiator cap relief pressure:Standard78-98kPa
(0.78 - 0.98 bar, 0.8 - 1.0 kg/cm
2, 11 - 14 psi)
Pull the negative pressure valve to open it.
Check that it closes completely when released.

Water Pump
CAUTION:
IWhen removing water pump assembly, be careful not to
get coolant on drive belt.
I Water pump cannot be disassembled and should be
replaced as a unit.
I Always replace with new gasket.
I After installing water pump, connect hose and clamp
securely, then check for leaks using radiator cap tester.
Refer to MA section.
REMOVAL AND INSTALLATION
1. Drain coolant from radiator and cylinder block.
Refer to MA section (ªChanging Engine Coolantº, ªENGINE
MAINTENANCEº).
2. Remove radiator upper hose.
3. Remove radiator shroud.
4. Remove cooling fan.
5. Remove drive belt. Refer to MA section, ªChecking Drive Beltº.
6. Remove insulator.
7. Remove vacuum pipe.
8. Remove TDC sensor. Refer to EM section, ªTDC sensor removal and installationº in ªTIMING GEARº.
9. Remove fan coupling with water pump.
10. Install in the reverse order of removal.
