12. Fill reservoir tank up to ªMAXº level, and re-install radiator cap.
13. Run the engine at approximately 2,000 rpm for about oneminute.
14. Stop engine and cool it down, then refill the radiator and the reservoir tank up to the specified level.
Checking Cooling System
CHECKING HOSES
Check hoses for proper attachment, leaks, cracks, damage, loose
connections, chafing and deterioration.
CHECKING RADIATOR CAP
Apply pressure to radiator cap by means of a cap tester to see if it
is satisfactory. Radiator cap relief pressure:78-98kPa
(0.78 - 0.98 bar, 0.8 - 1.0 kg/cm
2, 11 - 14 psi)
CHECKING COOLING SYSTEM FOR LEAKS
Apply pressure to the cooling system by means of a tester to check
for leakage. Testing pressure:157 kPa (1.57 bar, 1.6 kg/cm
2, 23 psi)
CAUTION:
Higher than the specified pressure may cause radiator dam-
age.

2. Remove fuel filter, using a suitable tool.
3. Wipe clean fuel filter mounting surface on fuel filter bracket andsmear a little fuel on rubber seal of fuel filter.
4. Screw fuel filter on until a slight resistance is felt, then tighten and additional more than 2/3 turn.
5. Install fuel filter sensor to new filter.
6. Bleed air from fuel line. Refer to Bleeding Fuel System in EC section.
7. Start engine and check for leaks.
DRAINING WATER
1. Loosen drain cock and drain water.
Loosening drain cock 4 to 5 turns causes water to start drain-
ing. Do not remove drain cock by loosening it excessively. If water does not drain properly, move the priming pump up and
down.
2. Bleed air. Refer to section EC for fuel system bleeding instructions.

Checking Injection Nozzle
WARNING:
When using nozzle tester, do not allow fuel sprayed from
nozzle to contact your hand or body, and make sure that your
eyes are properly protected with goggles.
1. Check initial injection pressure by pumping tester handle onetime per second.Initial injection pressure: Used Nozzle12,259 - 12,749 kPa
(122.6 - 127.5 bar, 125 - 130 kg/cm
2,
1,778 - 1,849 psi)
New Nozzle 12,749 - 13,730 kPa
(127.5 - 137.3 bar, 130 - 140 kg/cm
2,
1,849 - 1,991 psi)
I Always check initial injection pressure before installing
new nozzle.
Do not disassemble injection nozzle assembly. Entrust disas-
sembly or adjustment to BOSCH service shop.
2. Check spray pattern by pumping tester handle 4 to 6 times or more per second.
a. If main spray angle is within 30 degrees as shown, injec- tion nozzle is good.
b. It is still normal even if a thin stream of spray deviates from the main spray (pattern B).
3. If spray is not correct, clean injection nozzle tip or replace it.
I For details, refer to INJECTION NOZZLE ASSEMBLY in EC
section.

IBecause an auto tensioner adjustment mechanism is
provided, it is not necessary to check or adjust the tension
of accessory belt.

Removal
WATER PUMP, ALTERNATOR AND AIR CONDITIONER
BELT
1. Remove radiator shroud.
2. Contract and hold the auto tensioner using the following proce-dure.
a. Securely hold the 19 mm (0.75 in) hexagonal portion A of auto tensioner with a closed wrench.
I Preferably use a tool with a handhold of 500 mm (19.69 in) or
more in length.
I No bolts or nuts are required to be loosened during the opera-
tion.
b. Turn the hexagonal portion A in the direction shown by the arrow to contract the damper unit of the auto tensioner.
CAUTION:
I Because the tensioner has a high tension, it shall be
securely held and turned with a closed wrench.
I Because the hexagonal portion A of the tensioner is made
of aluminum and may be damaged by sudden input, turn
it slowly according to the contraction of the damper unit.
3. Remove the belt from the alternator pulley first, and then remove it from the other pulleys.
I If the tensioner is not held firmly, your finger may get caught
between the belt and the pulleys. Confirm the holding of the
tensioner, and then hold the belt side in the place away from
the pulleys to attach or remove the belt, paying attention to
prevent your finger from being caught.
CAUTION:
I When handling the belt, pay attention to prevent the oil or
coolant from adhering to the belt.
I Do not distort or bend the belt intensively.
Installation
IInstall the belt in the reverse order of removal.
I After installation of the belt, confirm that the belt engages the
pulleys securely.
I Depending on the engagement between the belt and the idler
pulley, noise (belt noise) may be heard when the engine is
started just after installation. This noise will stop with time.
Changing Engine Oil
WARNING:
IBe careful not to burn yourself, as 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. Remove drain plug and oil filler cap.

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.

2. Set theGmark of the filter body to the top position and dis-
charge the oil.
I Receive the oil discharged from the drain hose in a tray.
I About 500 cc (17.6 Imp fl oz) of oil will be discharged in about
3 minutes.
I The oil is discharged from the oil catcher to under the vehicle
through the drain hose.
3. Remove the filter body, and then remove the oil filter element.
CAUTION:
I If the engine oil gets on the engine or vehicle, thoroughly
wipe it off.
I Thoroughly wipe off the oil remaining in the oil catcher.
(This is to prevent misidentifying oil leaking from the oil
catcher as oil leaking from the engine.)
4. Remove the O-ring from the filter body.
I Press the O-ring in any direction with your finger, and pull on
the portion of the O-ring separated from the filter body to
remove it.
CAUTION:
Because wire and screwdrivers may cause damage to the fil-
ter body, do not use such tools.
INSTALLATION
1. Thoroughly remove foreign matter adhering to the inside of fil- ter body and O-ring mounting areas (of the body and oil cooler).
2. Install the oil filter element and O-ring to the filter body.
I Securely press the oil filter element into the filter body.
3. Install the filter body.
:20-24N ×m (2.0 - 2.5 kg-m, 15 - 18 ft-lb)
4. After warming up the engine, check that no engine oil leaks.
Changing Engine Coolant
WARNING:
To avoid the danger of being scalded, never change the cool-
ant when the engine is hot.
ÐDRAINING ENGINE COOLANTÐ
1. Move heater TEMP control knob all the way to HOT.
2. Remove undercover and disconnect lower radiator hose to drain coolant.
3. Remove radiator filler cap.

7. Move heater TEMP control knob all the way to HOT.
8. Fill radiator with coolant up to the filler neck.
For coolant mixture ratio, refer to MA-19.
9. Fill reservoir tank with coolant up to the MAX level.
Coolant capacity (With reservoir tank):10.6 (9-3/8 Imp qt)
Reservoir tank capacity (for MAX level): 0.75 (5/8 Imp qt)
Pour coolant through coolant filler neck slowly to allow air in
system to escape.
10. Install radiator cap.
11. Warm up engine to normal operating temperature.
12. Run engine at 2,000 rpm for 10 seconds and return to idle speed.
I Repeat 2 or 3 times.
Watch coolant temperature gauge so as not to overheat the
engine.
13. Stop engine and cool it down.
I Cool down using a fan to reduce the time.
14. Remove the radiator cap and check coolant level.
I If necessary, refill radiator up to filler neck with coolant.
15. Refill reservoir tank to Max line with coolant.
16. Repeat step 9 through step 15 two or more times.
17. Warm up engine, and check for sound of coolant flow while running engine from idle up to 2,000 rpm with heater tempera-
ture control set at several positions between COOL and HOT.
I Sound may be noticeable at heater water core.
18. If sound is heard, bleed air from cooling system by repeating steps 11 through 17 until coolant level no longer drops.
I Clean excess coolant from engine.
