Everyone who has its own car, sooner or later may face the need replacement of the belt generator. For such a procedure, you can, of course, contact the service center or the repair workshop, but you can also try to replace yourself using at the same time, our currently shown instructions.

How to independently replace the generator belt on the Opel

Step two. Now it is worth unscrew the top bolt of supports, after which a little (not completely) unscrew the bottom. Further, refuel under the first leg belt support. At the same time, you can very well help yourself with a mount.

Step Third. Tighten the upper bolt half, after which you completely unscrew the bottom bolt. Using the entire same mount, lift the support and impose a belt below it.

Step fourth. Spend a similar operation with a third foot of the support, after which the belt will be inside.

Pitch fifth. Now you need to throw the key on the tensioner bolt, after which the tensioner bolt is worth pulling away to weaken and remove the old belt. So, after you weakened the old belt, cut it out and remove it. After all of the above, it is necessary to fill a new strap on the pulleys, take the roller key, wear it and release it, the belt must stretch.

Step Six. Put the air filter back.

That's all, replacing a belt generator Opel is produced. For the entire operation, you should approximately go before half an hour, despite the fact that everything will be obtained from the first time and there will be no chandos. With all this, you will be able to save several hundred rubles for these thirty minutes, which, you see, not so bad for any wallet.

However, if you look at the other side, the repair of the Opel car is generally comprehensible, and if you are definitely not sure about your skills, it is better to charge any repair, including the replacement of the generator belt with highly qualified professionals. With all this, if you consult really professionals, then work will be performed literally in minutes and will not require any physical effort.

Many car owners neglect the condition of the belt of the attached units, believing that it is not necessary to change it. So far, at one point it does not break, burying the water pump, air conditioning and an amplifier of the steering wheel. In this article we will look at how to independently replace the drive belt on Opel Astra J.

Drive belt replacement time

According to the regulations maintenanceAt the Opel Astra H 1 6 replacing the drive belt should be carried out every 30 thousand hours of operation. The service life of these parts is measured in hours, not kilometers. For example, during idle in traffic. However, in practice, the service life of the part will depend highly on weather conditions, load on electrical appliances and driving style. Experienced car owners advise to prepare for replacement after 15-20 thousand or two years later.

Naturally, you should not forget about the routine diagnosis of the stretch strap. The main feature of the malfunction is a whistle associated with the strap slip. However, the whistle may be associated with fluid getting into the system components. Do not beat the alarm if you heard a whistle, say after the rain or stopping in the puddle. If a whistle appears when the vehicle's electronic system is loaded, it is necessary to urgently check its condition.

Small horizontal cracks are a permissible defect associated with wear. If there are no ribs on the surface and long vertical cracks appeared, the belt must be replaced urgently. Unacceptable defects include sections and disheveled ends from which the threads climb. In addition to the belt, it is also worth viewing the tensioner roller. It must be in a parallel condition relative to the thrust plates. If he is adjacent to them, it should be replaced.

Untimate belt replacement can lead to a cliff. Its opening will not compare with a cliff of the timing belt, but it is still a rather unpleasant phenomenon. First, the air conditioner will turn off in your car. And if without it, you can also get to the service, then without the power steering wheel, it will be much more difficult to do it. However, the most serious danger is the engine overheating. This is due to the fact that without the rotational moment, water pump Clears the supply of coolant into the engine. Therefore, on the way to the service, carefully follow the engine temperature sensor.

Belts Location in Opel Astra H

The main task of this part is to transmit the torque to the generator, air conditioning, the pump and the power steering. This is done by transferring torque from the crankshaft on the pulleys of these devices. In turn, the pulleys of devices convert the moment to the necessary type of movement or electricity. It is located with the left (if you get up before the hood) of the engine.

Preparation for replacement

Before replacing the drive belt on the Opel Astra H, the keys from the ignition should be removed and allow the car to cool. In no case do not replace the hot engine, otherwise you can get a serious burn. In addition to this hot or warm, the engine will not exhibit proper tension. This is due to the fact that when heated, the parts are expanding and displaced. Even if you exhibit the correct tension, as soon as the engine cools, the belt will weaken. Immediately before the procedure, you need to turn off the negative battery terminal. To replace you, you will need an end head for 19 and 14.

Replacement process

The replacement procedure on Opel Astra looks like this:

• We put the jack under the engine.
• Remove the fastening bolts and remove the front right wheel.
• Remove the right mudguard of the engine. For this, you unscrew the pallet mounts for 14 motor compartment And remove it. After that, unscrew the three bolts of the lower fastening of the mudguard, pull out the side lock and remove the mudguard.
• Remove the air cleaner. To do this, disconnect the air nozzle and unscrew the fastening bolts.
• We dismantle the engine cushion fastening.
• Weakening the tension, rotating the tensioner roller counterclockwise.
• Remove the belt of hinged units.
• We put on a new belt. After that, scroll the crankshaft into three full turns so that he would take the right position.
• We stretch the belt, rotating the tensioner clockwise.

This replacement procedure can be considered completed. However, before the back assembly, it is worth checking the tension. It is believed that the generator belt is tensioned correctly, if in the middle of the pulley of the generator and crankshaft It can not be twisted around its axis more than 90o. The degree of accompanying efforts to describe is difficult, but with experience this feeling comes automatically.

Differences of the replacement of the drive belt in other models Opel

The drive device of attachments is identical on the whole family of Opel Astra. This applies to models "f", "g", "h", "j" and "k". Moreover, in addition to small constructive differences Systems, replacing the drive belt in Opel Zafira 1.8 in essence it does not differ from replacing the drive belt on the Opel Astra J.

On repair, we have a car Opel Astra J, where you need to replace drive beltOtherwise, it is also called the belt of the auxiliary units, the generator belt. Show you detailed photo And the video instruction, how to make it with your own hands in the garage conditions.

We proceed to work, break off the bolts from the front right wheel, the jack machine and dismantle it. We need to remove half the fenders to make it unscrewing 4 fixing screws, three of them are visible immediately, and the fourth is under the bumper:

For unscrewing, use Torkes T20. Next, we remove 4 plastic rivets with a hider. After that, we get direct access to the drive belt. To remove it, it is necessary to remove the steering hydraulic belt at the beginning (GUR):

We dress on the tensioner of the drive belt key on 19:

Tyan counterclockwise. We remove and put a new stream belt, we have a Bosch company, article 1987947949. Lower it down, at the beginning we dress up on the pulley.

Then goes under the arch wheel, we skip it through the pulley of the generator, drive Roller. If you have difficulty with this, then it is better to draw a diagram in advance how the old belt stood. After you have traded the belt in all rollers and pulleys, the tensioner counterclockwise is touched by the key on 19. Do not forget to put back the gur belt. Next, we carry out an assembly in the reverse order.

Replacing the generator belt, that is, the drive of the auxiliary aggregates (pump, air conditioner and the generator) is largely similar to different engines. Differences are only in the options for the layout of stretch rollers and the features arising from this. Also on different engines the number of drive units may be different, which means the length of the belt will also be different.

Before removing the old belt, it is recommended to draw a tension circuit to be easier to navigate when installing. If the old belt is put back after the removal, it is worth drawing installation labels, in particular, to designate which way the belt is spinning. Incorrectly established old belt will fail much faster.

The belt rotates clockwiseIf you look at the engine from the belt drive.
