You will need: keys "13", "17".

Disconnect all cardan shafts from the transfer case

Remove the air conditioner condenser for repairs, as well as for dismantling the radiator of the engine cooling system

If you find oil leaking from under the front crankshaft oil seal, it needs to be replaced

Before replacing the oil seal, make sure that the crankcase gas recirculation system is not clogged

You will need: a pipe (gas) wrench, a screwdriver, a chisel, a punch, a hammer, a universal joint puller, a snap ring puller, a wire brush, penetrating lubricant (for example, WD-40)

Wheel speed sensors generate signals about the speed of each wheel of the vehicle, which are transmitted to the electronic control unit of the hydraulic unit.

Installing wiring harnesses on the body of a VAZ-2123 car

When repairing the electrical equipment of a car, sometimes you have to check all the wiring

When the ignition is turned on, voltage is supplied to the excitation winding of the generator (terminal "D" of the generator 9412.3701 and "B" of the generator 371.3701) through the control lamp in the instrument cluster (the lamp is on) and the resistors connected in parallel to it

In this article we will look at how to replace the sensors of the VAZ-2123 engine management system

You will need: 8 mm and 10 mm wrenches, Phillips and flat-head screwdrivers, pliers for removing retaining rings

The VAZ-2123 engine is equipped with a microprocessor control system (MSCS), i.e. a distributed fuel injection system with feedback, which combines the inextricably linked power supply and ignition subsystems

The main dimensions of the cylinder block are shown in Figure 1

The cylinder block is cast from special low-alloy cast iron

The ignition module is installed on the engine cylinder block on the left side. A faulty module cannot be repaired and must be replaced

Replace the shock absorber if there is a leak in the shock absorber fluid or if the damping efficiency is lost

The main dimensions of the connecting rod and piston group are shown in Figure 1

The piston is cast aluminum
