9. Remove power steering oil pump with piping connected from engine. Move it aside on suspension mem-
ber. Refer to PS-37, "
HYDRAULIC LINE" .
10. Remove front engine mounting and rear engine mounting through-bolts to remove suspension member.
11. Remove starter motor. Refer to SC-23, "
STARTING SYSTEM" .
12. Separate engine and transaxle and transfer assembly. Refer to MT-19, "
TRANSAXLE ASSEMBLY" .
INSTALLATION
Install in the reverse order of removal.

Do not allow engine oil to get on mounting insulator. Be careful not to damage mounting insulator.

When installation directions are specified, install parts according to the direction marks on them referring
to figure of components. Refer to EM-222, "
ENGINE ASSEMBLY" .

Make sure that each mounting insulator is seated properly, and tighten mounting bolts and nuts.
INSPECTION AFTER INSTALLATION
Inspection for Leaks
The following are procedures for checking fluids leak, lubricates leak and exhaust gases leak.

Before starting engine, check oil/fluid levels including engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to MA-17, "
RECOMMENDED FLUIDS AND LUBRICANTS" .

Before starting engine, bleed air from fuel piping. Refer to FL-18, "Air Bleeding" .

Run engine to check for unusual noise and vibration.

Warm up engine thoroughly to make sure there is no leakage of fuel, exhaust gases, or any oil/fluids
including engine oil and engine coolant.

Bleed air from lines and hoses of applicable lines, such as in cooling system.

After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to the
specified level, if necessary.

BASIC SERVICE PROCEDURE

BASIC SERVICE PROCEDUREPFP:00018
Fuel FilterEBS01172
DESCRIPTION
A water draining cock is on the lower side and a priming pump for bleeding air is on the upper side.
AIR BLEEDING
Pump the priming pump to bleed air.

When air is bled completely, the pumping of the priming pump
suddenly becomes heavy. Stop the operation at that time.

If it is difficult to bleed air by the pumping of the priming pump
(the pumping of the priming pump does not become heavy), dis-
connect the fuel supply hose between the fuel filter and the fuel
gallery. Then, perform the operation described above, and make
sure that fuel comes out. (Use a pan, etc. so as not to spill fuel.
Do not let fuel get on engine and other parts.) After that, connect
the hose, then bleed air again.

Start engine and let it idle for at least 1 minute after performing
air bleeding.
WATER DRAINING
1. Remove the fuel filter, filter bracket, protector assembly from the dash panel as follows.
a. Remove the air cleaner case (upper), air duct assembly, and vacuum hose for brake booster (between the
vacuum pump and vacuum pipe).
CAUTION:
After the duct is removed, cover the opening with gum tape, etc. to prevent foreign object from
getting into the engine during the operation.
b. Remove the mounting nuts on the dash panel, then remove the fuel filter, filter bracket, and protector
assembly from the dash panel.

It is not necessary to disconnect the fuel hose.
2. Using a tool such as a pliers, loosen the water draining cock at
the bottom of the fuel filter.
Loosening drain cock four to five turns causes water to
start draining.
Do not remove drain cock by loosening it excessively.
If water dose not drain properly, move the priming up and down.
CAUTION:
When the water is drained, the fuel is also drained. Use a
pan, etc. to avoid fuel adherence to the rubber parts such as
the engine mount insulator.
Do not over-tighten the water draining cock. This will dam-
age the cock thread, resulting in water or fuel leak.
3. Bleed air of the fuel filter. Refer to EC-994, "
AIR BLEEDING" .
4. Start the engine.
Fuel Pump Learning Value ClearingEBS01173
DESCRIPTION
In order to always keep optimum fuel pressure in fuel rail, the ECM controls fuel pump in high precision with
monitoring the signal of fuel rail pressure sensor.
Accordingly, the ECM always learns characteristic value of fuel pump. Fuel Pump Learning Value Clearing is
an operating to clear the value of the fuel pump learning.
It must be performed after the fuel pump is changed. When the ECM is replaced with brand new one, the Fuel
Pump Learning Value Clearing is not necessary to be performed. If the ECM to be replaced has the possibility
of learning the characteristic value of fuel pump, the Fuel Pump Learning Value Clearing is necessary to be
performed after the ECM has been replaced.
OPERATION PROCEDURE
NOTE:
When removing fuel pump, perform Fuel Pump Learning Value Clearing before starting engine.

REMOVAL
1. Remove air duct, air cleaner case and mass air flow sensor assembly. Refer to EM-142, "AIR CLEANER
AND AIR DUCT" .
2. Remove fuel filter protector.
3. Disconnect fuel hoses at fuel filter bracket.
CAUTION:
Plug the pipe to prevent fuel from draining.
4. Remove fuel filter with fuel filter bracket.
CAUTION:
Do not splash fuel during removal. If fuel is splashed,
immediately wipe it off.
5. Using band-type fuel filter wrench (commercial service tool),
remove fuel filter.
6. Turn fuel filter upside down to drain fuel.
7. Remove drain plug from fuel filter.
INSTALLATION
Note the following, and install in the reverse order of removal.

Replace O-ring on drain plug with new one.

Screw the fuel filter by hand until packing contacts sealing surface of bracket. Then tighten it by turning
approximately 2/3 turn.

After installation, bleed air from fuel line. Refer to FL-18, "Air Bleeding" .
INSPECTION AFTER INSTALLATION
Make sure there is no fuel leakage at connections in the following steps.

Start the engine and rev it up and make sure there is no fuel leakage at connections.

FUEL FILTER

Air BleedingEBS00BLB
After fuel filter is replaced and after fuel system components are
removed/installed, bleed air from fuel line as follows:

Move priming pump up and down to bleed air from fuel path.

When air is bled, pumping of priming pump becomes heavy stop
operation at that time.

Crank engine until it starts. Do not crank engine for more than
30 seconds.

If engine does not start, stop cranking and repeat step 1 above.

If engine does not operate smoothly after it has started, race it
two or three times.

If air cannot be bled easily (pumping of priming pump does not
become heavy), disconnect feed-side of hose between fuel filter and electronically controlled fuel pump.
After that, operate priming pump and confirm that fuel comes out.
CAUTION:
Prepare a tray to collect fuel. Prevent fuel from adhering to rubber parts, especially the engine
mounting insulator.
Draining Water from Fuel FilterEBS00MRU
1. Prepare a tray at the drain hose open end.
2. Loosen drain cock, and operate priming pump to drain water
from fuel filter.
CAUTION:

Water in filter is drained with fuel. Prepare larger capacity
pan than fuel filter volume.

Drained water is mixed with fuel. Prevent fuel from adher-
ing to rubber parts such as engine mounting insulator.
3. After draining, close drain cock by hand.
CAUTION:
If drain cock is tightened excessively, it may be damaged
and fuel will leak. Do not use tools to tighten drain cock.
4. Bleed air in fuel piping. Refer to FL-18, "
Air Bleeding" .
5. Start engine and make sure there is no fuel leakage.
