Precautions
LIQUID GASKET APPLICATION PROCEDURENJLC00011. 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.

Oil Pressure CheckNJLC0004WARNING:
+Be careful not to burn yourself, as the engine and oil may
be hot.
+For M/T models, put gearshift lever in Neutral ªNº posi-
tion. For A/T models, put selector lever in Park ªPº posi-
tion.
1. Check oil level.
2. Remove oil pressure switch.
SLC926-A
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.

Oil Pump
REMOVAL AND INSTALLATIONNJLC0005+Make sure that O-ring is fitted properly.
1. Drain engine oil.
2. Remove drive belts.
3. Remove oil pan. Refer to EM-20, ªOIL PANº.
4. Remove oil strainer.
5. Remove front cover. Refer to EM-23, ªTIMING CHAINº.
6. Install front cover.
7. Reinstall parts in reverse order of removal.

INSPECTIONNJLC0007Using a feeler gauge, check the following clearances.
Standard clearance:
For Sedan
Unit: mm (in)
Body to outer rotor radial clearance10.114 - 0.200 (0.0045 - 0.0079)
Inner rotor to outer rotor tip clearance
2Below 0.18 (0.0071)

Body to outer rotor axial clearance40.030 - 0.090 (0.0012 - 0.0035)
Inner rotor to brazed portion of hous-
ing clearance50.045 - 0.091 (0.0018 - 0.0036)
For Hatchback
Unit: mm (in)

+If the tip clearance (2) exceeds the limit, replace rotor set.
+If body to rotor clearances (1, 3, 4, 5) exceed the limit,
replace front cover assembly.

REGULATOR VALVE INSPECTIONNJLC00081. Visually inspect components for wear and damage.
2. Check oil pressure regulator valve sliding surface and valve
spring.
3. Coat regulator valve with engine oil.
Check that it falls smoothly into the valve hole by its own
weight.
If damaged, replace regulator valve set or front cover assem-
bly.
SLC101B
4. Check regulator valve to front cover clearance.
Clearance 6:
For Sedan
0.040 - 0.097 mm (0.0016 - 0.0038 in)
For Hatchback
0.052 - 0.088 mm (0.0020 - 0.0035 in)
If it exceeds the limit, replace front cover assembly.
SMA915C
Changing Engine OilNJLC0035WARNING:
+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.
1. Warm up engine, and check for oil leakage from engine com-
ponents.
2. Stop engine and wait more than 10 minutes.
3. Remove drain plug and oil filler cap.
4. Drain oil and refill with new engine oil.
Oil specification and viscosity:
+API grade SG, SH or SJ
+ILSAC grade GF-I & GF-II
Refer to MA-16, ªRECOMMENDED FLUIDS AND LUBRI-
CANTSº.
Refill oil capacity (Approximate):
Unit:!(Imp qt)
With oil filter change 2.7 (2-3/8)
Without oil filter change 2.5 (2-1/4)
Dry engine (engine overhaul) 3.1 (2-3/4)
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.
