Check the alternator belt tension, not less frequently than every 15 thousand kilometers. This requirement requires the manufacturer. Put the car on a level surface, turn on the hand brake to prevent any movement of the machine when performing work. After that, stop the engine and remove the key from the ignition switch.
Prepare the necessary tools: Vernier caliper or a ruler and wrench. Then disconnect the wire from "the minus" of the battery. Lift the hood and find the alternator belt, which first, inspect visually to detect cracks, fading, and various imperfections.
Then make sure you have enough hard he stretched. To do this, press your thumb on his side of the constriction. Holding the strap in this position, take a Vernier caliper or a regular ruler and measure the amount that deviated from the original position. If this value is greater than 8-12 mm, the belt must be tightened.
To test yourself, grasp the belt with two fingers and rotate it at the maximum angle. If this angle is more than 90 degrees, the tension adjustment can not be avoided. Pick up the wrench of the desired radius and gently loosen the nut with which the generator is attached to the tension bracket car.
Using the adjustment bolt to set the optimum belt tension of the generator. Be careful at the time of adjustment, the load on the belt was old, and he did not deviate from the preset position. Then tighten the nut of the generator to a tension lath with time, which shall not be less than 21 N*m. Remember that regular checking and optimum belt tension generator will allow you to extend the life of the vehicle.
Prior, removal of the generator priors. The generator can be removed for repair or replacement when it fails and when removing the engine. Disconnect the terminal wires from the "minus" terminal of the battery. Remove the splash guard to the power unit. Remove the drive belt of the generator .
As you know, the generator priors produces about 13.8 V under load. For a normal battery voltage of 13.8 desirable...14.4 V, so increasing the voltage of the generator we will improve charging. For removing the diode bridge of the generator priors enough to pull off plastic cover and remove the diode bridge itself.
