4- and 6-cylinder in-line engines
Removing
1. Turn off the ignition.
2. Remove the air filter cross tube.
Pic. 5.38. Removing the spark plug cover: 1 - cover; 2, 3 - pin connector
3. Remove cover 1 (pic. 5.38) spark plugs.
Note. The figure corresponds to a 6-cylinder in-line engine.
4. Disconnect from coils 3 ignition contact sockets.
Pic. 5.39. Ignition coil: 1, 3 – connectors; 2 - guide pin; 4 - ignition coil
5. Disconnect the connectors of the 2 high voltage wires.
Note. On fig. 5.39 connector 3 ignition coil 4 is connected to the spark plug. Connector 1 is connected to the spark plug via a high voltage wire. Guide pin 2 connects the ignition coil to «weight».
Pic. 5.40. Connection diagram of ignition coils of a 6-cylinder in-line engine. The numbers indicate the tips of the spark plugs from the 1st to the 6th cylinders; B - wires
On fig. 5.40 shows the connection diagram of the ignition coils with spark plugs for a 6-cylinder in-line engine.
6. Remove the ignition coils upwards.
Installation
7. Establish coils of ignition on former places and connect wires according to fig. 5.40.
8. Replace the spark plug cap.
9. Install the air filter cross tube.
V6 engine
Removing
1. Turn off the ignition.
2. Remove the mass air flow sensor along with the intake pipe.
Pic. 5.41. Removing the ignition coil on a V6 engine: 1, 3 - pin connector; 2 - screw; 4 - mounting position; 5 - ignition coil; 6 - spark plug
Disconnect from coil 5 (pic. 5.41) ignition both high voltage wire connectors.
Note. Pay attention to mounting position 4 marked on the ignition coil and on the engine. The spark plug tips are marked because each cylinder has two spark plugs. Pin connector «A» on the ignition coil must be connected to the tip «TO» spark plug. connector «b» - with tip «G» spark plug.
4. Disconnect the connector 3 from the ignition coil.
5. Turn away the screw 2 and remove the ignition coil.
Installation
6. Install the ignition coil and tighten screw 2.
7. Plug in connector 1.
8. Connect the connectors 1 to the ignition coil.
Attention! Do not mix up the connectors, they are labeled. connector «A» on the ignition coil connects to the tip «TO» spark plugs, connector «b» - with tip «G» spark plug.
9. Establish the gauge of the mass expense of air with an inlet pipe.
V8 engine
Removing
1. Turn off the ignition.
Pic. 5.42. Removing the ignition coil on a V8 engine: 1 - cover; 2 - fastening detail; 3 - ignition coil; 4 - spark plug
2. Turn away bolts of fastening and remove covers 1 (pic. 5.42) from the engine.
3. Disconnect the connectors on the side of each ignition coil.
4. Turn away the bolts fastening a detail 2.
5. Remove ignition coils 3 from spark plugs 4 upwards.
Installation
6. Install ignition coils 3 on spark plugs 4.
7. Wrap the bolts fastening part 2.
8. Connect the connectors to each coil.
9. Fix covers 1 on the engine.
