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.

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.

5. Check oil level.
6. Start engine and check area around drain plug and oil filter for
oil leakage.
7. Run engine for a few minutes, then turn it off. After several
minutes, check oil level.

Changing Oil FilterNJLC0010The oil filter is a small, full-flow cartridge type and is provided with
a relief valve.
+Use Tool KV10115801 for removing oil filter.
SLC275B
1. Remove oil filter with Tool.
WARNING:
Be careful not to burn yourself, as the engine and the engine
oil are hot.
SMA010
2. Clean oil filter mounting surface on cylinder block. Coat rubber
seal of new oil filter with engine oil.
SMA229B
3. Screw in the oil filter until a slight resistance is felt, then tighten
an additional 2/3 turn.
4. Add engine oil.
Refer to Changing Engine Oil.

Precautions
LIQUID GASKET APPLICATION PROCEDURENJLC00141. 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.
