Removal
Cars with 1.4 liter engine (E7J)
The ignition coil is located on the front wall above the brake fluid reservoir.
1. Disconnect the high tension wire from the ignition distributor at terminal 1 of the ignition coil (see illustration).
4.1 Disconnect the high tension wire from the ignition distributor at terminal 1 of the ignition coil
2. Disconnect the multi-pin plug 2 by compressing the locking spring (see illustration 4.1).
3. Remove the coil together with the holder by unscrewing the mounting bolts (see arrows in illustration 4.1).
Installation
4. Replace the holder and ignition coil and secure them with bolts.
5. Connect the high voltage wire and multi-pin plug.
Cars with 1.6 liter engine (K7M)
Cars with this engine have two twin ignition coils flanged to the cylinder head. When working on the valve timing mechanism, the coils must be removed together with the fastener.
6. Turn off the ignition.
7. Remove the high-voltage wire tips 1 from the spark plugs (see illustration). In this case, you should pull by the tips, not by the wires. To remove the tips, you need to apply a certain amount of force. Immediately after disconnecting the tip, mark it so that during assembly you can install it on the correct spark plug.
4.7 Remove the high voltage wire tips 1 from the spark plugs
8. Disconnect the capacitor wire by disconnecting the black plug 2 and releasing it from the guide 3 (see illustration 4.7).
9. Unscrew the bolts securing the high-voltage wire bus on the cylinder head (see arrows in the illustration).
4.9 Unscrew the bolts securing the high-voltage wire bus on the cylinder head (see arrows)
10. Unscrew the six bolts 1 that secure the ignition coil to the bracket (see illustration).
4.10 Unscrew the six bolts 1 that secure the ignition coil to the bracket
11. Disconnect the multi-pin plug 2 (see illustration 4.10).
12. Unscrew the four bolts 3 securing the ignition coil bracket to the cylinder head (see illustration 4.10).
Installation
13. Fasten the ignition coil bracket to the cylinder head with bolts.
14. Connect the ignition coil multi-pin plug.
15. Secure the ignition coils to the bracket.
16. Connect the wire to the capacitor, place it in the guide and fix it.
17. Connect the high-voltage wires to the ignition coils, following the markings.
Cars with 1.4-/1.6-liter petrol engine (K4J/K4M)
18. Disconnect tip 1 of the high-tension wire from the ignition coil. Pull on the tip itself, not on the wire (see illustration).
4.18 Disconnect tip 1 of the high-tension wire from the ignition coil. Pull on the tip itself, not on the wire
19. Unscrew bolt 2 (see illustration 4.18).
20. Remove coil 3 from the spark plug (see illustration 4.18).
When assembling, tighten bolt 2 with a force of 15 Nm (see illustration 4.18).
Attention! Two ignition coils are connected in series to the engine control unit. Terminal 1 of the control unit corresponds to cylinders 2 and 3, terminal 32 - to cylinders 1 and 4.
21. Cars with a 1.4 liter petrol engine (E7J): Remove the distributor cap by unscrewing the mounting bolts (see arrows in the illustration). The distributor cap must be dry and free of puncture marks from the inside. The carbon brush in the center of the distributor cap in the installation position must press the distributor runner and must not be damaged or significantly worn. If these defects are present, the cap must be replaced.
