Ignition System - 1.8L: Removal & Installation Kia Spectra II

REMOVAL

Scheme 17

1. Disconnect negative battery terminal.
2. Carefully remove high tension leads.
3. Use compressed air to blow any dirt or debris from around spark plug hole.
4. Check that spark plug fits squarely in spark plug socket and remove spark plug.

Scheme 18

Scheme 19

1. Reconnect negative battery cable.
2. Connect spark plug to high tension lead.
3. Hold spark plug with insulated pliers 0.2 to 0.39 inch (5~10 mm) from a ground. WARNING: Do not touch vehicle body during following instructions.
4. While holding spark plug, have a second person crank engine. Verify that a strong blue spark jumps from spark plug to ground.
5. If there is no spark or the spark is weak, check for, and implement correction: Carbon deposits. Clean out or replace plug. Oil fouling. Correct oil problem, replace plug. Worn or burnt electrode. If present, replace plug. Broken or burned ceramic insulator. If present replace plug. Damaged spark plug ring. If so, replace ring. Improper spark plug gap. Regap if possible, otherwise replace plug. Gap: 0.027~0.031 inch (0.7~0.8 mm)

INSTALLATION

1. Install spark plug into cylinder head. Tightening torque: 18~22 lb-ft (25~30 N.m, 2.5~3.0 kg-m)
2. Reconnect high-tension leads.
3. Reconnect negative battery cable.

Scheme 20

1. Disconnect from coil and spark plugs.
2. Check for breaks in insulation.
3. Check inside high tension lead connectors for corrosion or carbon deposits.
4. Connect high tension lead to an ohmmeter and check resistance. Resistance: 16 kohms per 3.28 feet (1 m)
5. Replace if defective.

Scheme 21

1. Disconnect negative battery cable.
2. Disconnect ignition coil connector.
3. Turn ignition switch to ON.
4. Measure voltage between blue wire and green wire at ignition coil connector. Voltage: approximately 12 Volts
5. If no voltage, check main fuse, ignition switch and wire harness.

Scheme 22

Scheme 23

1. Using an ohmmeter, check resistance of primary coil. Connect one lead of ohmmeter to the positive (+) terminal and the other lead to the negative (-) terminal. If not within specification, replace coil. Remember the unit has two coil assemblies, so both must be checked. Primary coil resistance: 0.45~0.55 ohms @ 68°F (20°C)
2. Using an ohmmeter, check resistance of the secondary coil. If not within specification, replace coil. Remember that you must check resistance of both top and bottom secondary coils. If one is out of specification replace the whole unit. Secondary coil resistance: 13~15 kohms @ 68°F (20°C)

1. Disconnect battery cable.
2. Disconnect high-tension leads.
3. Disconnect ignition coil connectors.
4. Remove four ignition coil mounting bolts.
5. Remove ignition coils.

Scheme 24

1. Position two coils above No. 2 and No. 4 spark plugs, and firmly push down to connect.
2. Insert and tighten four ignition coil mounting bolts. Tightening torque: 14~19 lb-ft (19~25 N.m, 1.9~2.6 kg-m)
3. Reconnect ignition coil connectors.
4. Reattach high tension leads. Leads are marked for correct connection.
5. Reconnect battery cable.
