Recommendation: It is more convenient to replace the high-voltage spark plug wires one by one.
Location of high-voltage spark plug wires on the VAZ 2112 (l,5i)* engine: 1 - first cylinder wire tip; 2 - second cylinder wire tip; 3 - third cylinder wire tip; 4 - plastic bracket securing the high-voltage wire of the third cylinder; 5 - ignition module; 6 - fourth cylinder wire tip; 7 - plastic bracket for fastening high-voltage wires of the first, second and fourth cylinders
* Engine trim removed.
Removal
1. We are preparing the vehicle for repair work (see points 1 and 2 "Preparing a car for maintenance and repair"), and turn off the ignition.
2. Remove the decorative engine cover (see "Engine trim - removal and installation").
3. Remove the wire tip from the spark plug well.
4. Disconnect the other end of the spark plug high-voltage wire from the ignition module.
5. Remove the wire of the first cylinder.
Similarly, we remove the high-voltage wires of the spark plugs of the other engine cylinders.
Warning: Spark plug wires are not interchangeable. Wires must be connected to the ignition module in accordance with the cylinder number (see "Ignition module of the VAZ 2112 engine (1.5i) - checking, removal and installation"). The wire insulation is marked with the serial number of the cylinder.
Installation
We install all removed parts on the car in the reverse order of removal.
