4 cylinder engine
Removing
1. Disconnect the plug connection between engine and ignition coils (X26/24).
2. Remove and set aside the washer reservoir.
3. Unscrew the intake manifold bracket.
4. If present, disengage the tempomat linkage.
5. Remove the high voltage wires from the ignition coils (arrow). Remove the bolts (20/1) to the ignition coils.
6. Open protective caps (20/2) on the underside of the ignition coils. Mark the wires at terminals 15 and 1 with adhesive tape and unscrew them.
7. Pull coil (Т1/1) And (Т1/2).
Attention! The connecting elements are energized up to 400 volts. Therefore, it is always necessary to connect the clamps/core pack to the car body.
8. Mount the ignition coils in the reverse order of removal. Accordingly, one ignition coil energizes two spark plugs.
6 cylinder engine
Removing
1. Remove the air cleaner cross tube by loosening the hose clamps.
2. Unscrew the protective casing of the spark plugs (5/1).
3. Remove the plugs of the control circuit wires on the ignition coils (arrows).
4. Remove the plugs of the high voltage wires at the output of the secondary circuit (Tb).
Attention! Ignition coils (T1) fitted with a spark plug through (Ta) directly to the spark plug. Secondary output (Tb) using a high voltage wire, it is supplied to the corresponding spark plug. guide pin (W) at the same time it is an element for connecting the ignition coil to the housing.
5. Pull up the ignition coil.
Attention! The primary circuit connections are energized up to 400 volts! Therefore, the clamp/core pack must always be connected to the car body.
Installation
Installation is made in sequence, return to removal. The figure shows the connection diagram of the ignition coils and spark plugs. Accordingly, one ignition coil powers two spark plugs with high voltage.
