LIQUID GASKET APPLICATION PROCEDURE
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 or equivalent.)

Be sure liquid gasket is 4.0 to 5.0 mm (0.157 to 0.197 in) wide
for SR engine and 3.5 to 4.5 mm (0.138 to 0.177 in) wide for
QG and CD engine (for oil pan).

Be sure liquid gasket is 2.0 to 3.0 mm (0.079 to 0.118 in) wide
(in areas except oil pan).
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.

Be careful not to burn yourself, as the engine and oil may
be hot.

Put gearshift lever in Neutral “N” position.
1. Check oil level.
2. Remove oil pressure switch.
3. Install pressure gauge.
4. Start engine and warm it up to normal operating temperature.
5. Check oil pressure with engine running under no-load.
Engine speed
rpmApproximate discharge pressure
kPa (bar, kg/cm2, psi)
600More than 98 (0.98, 1.0, 14)
2,000More than 294 (2.94, 3.0, 43)
6,000More than 392 (3.92, 4.0, 57)
