Installation Procedure
1. Check the piston ring gap and apply the engine oil to
the piston pin and the connecting rod bushing.
2. Connect the piston and the connecting rod by press-
ing in the piston pin (6) and install the snap ring to the
groove.
3. Clean the cylinder bore, connecting rod bearing jour-
nal, connecting rod bearing shell and the piston and
coat them with engine oil.
4. Install the piston ring.
5. Install the piston so that the arrow on the piston head
faces to the forward of the vehicle.
6. After aligning the connecting rod and the bearing cap
mark (// or a number), tighten the bolts.

Functions
1. Firing order : 1 -- 5 -- 3 -- 6 -- 2 -- 4
2. The ignition cables are located on the cylinder head
cover. Each ignition coil provides the high voltage to
two spark plugs simultaneously.
-- T1/1 : cylinder 2 and 5
-- T1/2 : cylinder 3 and 4
-- T1/3 : cylinder 1 and 6
3. The secondary output voltage (5a) is supplied to the
No.2 cylinder spark plug through the spark plug con-
nector. The secondary output voltage (5b) is supplied
to the No.5 cylinder spark plug through the ignition
cable. The guide pin (W) acts as a ground while the
ignition cable is operated.
Removal & Installation Procedure
1. Disconnect the negative battery cable (1).
2. Remove the ignition cable connector from the ignition
cable.
3. Disconnect the secondary spark plug connectors
from the each spark plugs and remove the ignition
cable bolt and ignition cable.
Installation Notice
Tightening Torque
9--11NSm (80 -- 97 lb-in)
DMake sure that the ignition cables are correctly
routed.
DExactly install the ignition cable guide pin into the
vehicle to be grounded.
4. Installation should follow the removal procedure in
the reverse order.

IGNITION COIL
YAA1F240
The Electronic Ignition (EI) system ignition coil is located on the cylinder head cover. The double ended coils receive
the signal for the Engine Control Module (ECM) which controls the spark advance.
Each EI system ignition coil provides the high voltage to two spark plugs simultaneously;
T1/1: cylinder 2 and 5
T1/2: cylinder 3 and 4
T1/3: cylinder 1 and 6
The EI system ignition coil is not serviceable and must be replaced as an assembly.

Notice:Before removal, the fuel rail assembly may be
cleaned with a spray-type cleaner, following package in-
structions. Do not immerse the fuel rails in liquid clean-
ing solvent. Use care in removing the fuel rail assembly
to prevent damage to the electrical connectors and in-
jector spray tips. Prevent dirt and other contaminants
from entering open lines and passages. Fittings should
be capped and holes plugged during service.
Important:If an injector becomes separated from the
rail and remains in the cylinder head, replace the injector
O-ring seals and the retaining clip.
12. Remove the injectors and the fuel rail carefully.
13. Remove the fuel injector retainer clips.
14. Remove the fuel injectors by pulling them down and
out.
15. Discard the fuel injector O-rings.
16. Lubricate the new fuel injector O-rings with engine
oil. Install the new O-rings on the fuel injectors.
17. Perform a leak check of the fuel rail and fuel injec-
tors.
18. Installation should follow the removal procedure in
the reverse order.

Removal and Installation Procedure
1. Relieve the coolant system pressure.
2. Disconnect the negative battery cable.
3. Disconnect the engine coolant temperature sensor
connector.
Notice:Take care when handling the engine coolant
temperature sensor. Damage to the sensor will affect
the proper operation of the fuel injection system.
4. Remove the engine coolant temperature sensor
from the pump hosing.
