Changing Engine Oil
WARNING:
IBe careful not to burn yourself, as the engine oil is hot.
I 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.
3. Remove dipstick, oil filler cap and drain plug.
4. Drain oil.
5. Install drain plug.
CAUTION:
I Be sure to clean drain plug and install with new washer.
Drain plug:
: 29-39N ×m(3.0 - 4.0 kg-m, 21 - 29 ft-lb)
6. Fill slowly with new oil whilst not exceeding the maximum level.
Oil specification and viscosity:
I See ªRECOMMENDED FLUIDS AND LUBRICANTSº (MA-
17).
Oil capacity (Approximately):
Unit: (Imp qt)
Drain and refill
With oil filter change 6.2 (5-1/2)
Without oil filter change 5.5 (4-7/8)
CAUTION:
IThe refill capacity depends on the oil temperature and
drain time. Use these specifications for reference only.
Always use the dipstick to determine when the proper
amount of oil is in the engine.
7. Install dipstick and filler cap.
8. Start engine. Check area around drain plug and oil filter for any sign of oil leakage.
9. Run engine for a few minutes, then turn it off. After several minutes check oil level again.
10. If necessary, add oil whilst not exceeding the maximum level.
Changing Oil Filter
1. Remove oil filter with a suitable wrench.
WARNING:
Be careful not to burn yourself as engine and oil is hot.

3. Drain oil and fill with new engine oil.Oil grade:API CF4 or ACEA B3-96.98 or ACEA B3/E3-96.98
Viscosity: See ªRECOMMENDED FLUIDS AND
LUBRICANTSº, MA-1009.
Refill oil capacity (approximate): Without oil filter change5.2 (4-5/8 Imp qt)
With oil filter change 5.7 (5 Imp qt)
CAUTION:
I Be sure to clean and install oil pan drain plug with washer.
Drain plug:
:54-58N ×m (5.5 - 6.0 kg-m, 40 - 43 ft-lb)
I The refill capacity changes depending on the oil tempera-
ture and drain time; use these valves as a reference and be
certain to check with the dipstick when changing the oil.
4. Check oil level.
5. Start engine. Check area around drain plug and oil filter for any sign of oil leakage.
6. Run engine for a few minutes, then turn it off. After 10 minutes check oil level.
Changing Engine Oil Filter
REMOVAL
1. Insert a suitable tool with a 12.7 mm square (1/2 inch square)such as an extension bar and ratchet handle into the filter body,
and loosen the body by approximately 4 turns.
WARNING:
Be careful not to burn yourself, as the engine and engine oil
are hot.

Trouble diagnosis of turbocharger
Preliminary check:
Check that the VNT control valve system has no malfunction. Refer
to EC section, ªECM Terminals and Reference Valueº in ªTROUBLE
DIAGNOSIS Ð GENERAL DESCRIPTIONº.
ICheck that the engine oil level is between MIN and MAX of the
dipstick. (When the engine oil amount is more than MAX, the
oil flows into the inlet duct through the blow-by gas passage,
and the turbocharger is misjudged failure.)
I Ask the customer if he/she always runs the vehicle in idle
engine speed to cool the oil down after driving.
I Replace the turbocharger assembly when any malfunction is
found after unit inspections specified in the table below.
I If no malfunction is found after the unit inspections, judge that
the turbocharger body has no failure. Check the other parts
again.

Blades are bent or broken.
After checking both turbine and compressor,
inspect rotor shaft end play. There is resistance when the rotor shaft
is rotated by your fingertips.
ggq
The rotor shaft sometimes does not
rotate by your fingertips.
There is too much play in the bearing. g gqg

Operation of VNT control actuator I
The actuator does not operate
smoothly when vacuum pressure is
gradually applied.
I Stroke amount is not in compliance
with the vacuum pressure. q
: Large possibility
q: Medium possibility
g: Small possibility
INSTALLATION
1. Install catalyst.
:29-39N ×m (2.9 - 3.3 kg-m, 21 - 23 ft-lb)
Place the protruding area of the gasket between the turbocharger
and the exhaust outlet upwards, and install the lipped side to the
turbocharger side. Refer to the figure, EM-14.
2. Install in the reverse order of removal.
