2. Before installing new oil filter, clan the oil filter mounting surface
on cylinder block and coat the rubber seal of the oil filter with
a little engine oil.
3. Install oil filter.
When installing oil filter, screw it in until a slight resistance is
felt, then tighten an additional 2/3 turn or more.
4. Add engine oil.
Refer to Changing Engine Oil.
Changing Engine Coolant
WARNING:
To avoid the danger of being scalded, never attempt to change
the coolant when the engine is hot.
1. Set heater ªTEMPº control lever all the way to ªHOTº position.
2. Remove radiator cap and engine under cover.
3. Disconnect lower radiator hose to drain coolant.
Remove reservoir tank, drain coolant, then clean reservoir tank.
Re-install tank temporarily.
4. Remove cylinder block drain plug located at left rear of cylin-
der block.
5. Drain coolant and then tighten drain plug securely.
IApply sealant to the thread of drain
:30-40N×m (3.1 - 4.1 kg-m, 22.1 - 29.5 ft-lb)
6. Connect lower radiator hose.
7. Fill radiator and reservoir tank with water. Re-install radiator
cap and warm up engine.
8. Stop engine and wait until cools down.
9. Drain water.
10. Repeat step 2 through step 9 two or three times, until clear
water begins to drain from radiator.
11. Fill radiator with coolant up to the specified level.
Follow instructions attached to anti-freeze container for mixing
ratio of anti-freeze to water.
Coolant capacity (with reservoir tank):
10.0(8-3/4 Imp qt)
Slowly pour coolant through coolant filler neck to allow air in
system to escape.

12. Fill reservoir tank up to ªMAXº level, and re-install radiator cap.
13. Run the engine at approximately 2,000 rpm for about one
minute.
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 - 1.0 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:
98 kPa (0.98 bar, 1.0 kg/cm
2, 14 psi)
CAUTION:
Higher than the specified pressure may cause radiator dam-
age.
Checking and Replacing fuel filter and Draining
Water
Be careful not to spill fuel in engine compartment. Place a rag
to absorb fuel.
REPLACING FUEL FILTER
1. Remove fuel filter sensor and drain fuel.

2. Remove fuel filter, using a suitable tool.
3. Wipe clean fuel filter mounting surface on fuel filter bracket and
smear 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 one
time per second.
Initial injection pressure:
Used Nozzle
12,259 - 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)
IAlways 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.
IFor details, refer to INJECTION NOZZLE ASSEMBLY in EC
section.

trol lever pin and the injection pump control lever is within the
specified limits.

operating.
3. Then check the idle speed when the air conditioner is operat-
ing and make sure it is correct.

Checking Drive Belt
IBecause an auto tensioner adjustment mechanism is
provided, it is not necessary to check or adjust the tension
of accessory belt.
1. Inspect for cracks, fraying, wear or oil adhesion. Replace if
necessary.
The belts should not touch the bottom of the pulley groove.
2. Check the damper unit of the auto tensioner for oil leaks.

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.
IPreferably use a tool with a handhold of 500 mm (19.69 in) or
more in length.
INo 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:
IBecause the tensioner has a high tension, it shall be
securely held and turned with a closed wrench.
IBecause 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.
IIf 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:
IWhen handling the belt, pay attention to prevent the oil or
coolant from adhering to the belt.
IDo not distort or bend the belt intensively.
Installation
IInstall the belt in the reverse order of removal.
IAfter installation of the belt, confirm that the belt engages the
pulleys securely.
IDepending 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.
IProlonged 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.
