According to the committee of automakers, in the period from 2004 to 2008 it was one of the best-selling in Russia. Motorists appreciated the increased comfort compared to the previous model, as well as high maintainability and the ability to eliminate minor breakdowns in garage conditions. This, you see, is an important factor during the uncontrollable rise in service prices.

Carrying out preventive examinations and minor repairs, such as chevrolet Niva alternator belt even a novice driver can do it. But first you need to make sure of the need for such events.

When to Change Accessory Drive

The manufacturer recommends putting a new gear every 50,000 km. Some specimens can go even longer, so periodic inspection of the product is essential. To check the technical condition of the rubber drive, follow these steps:

1. Mark the starting point of the inspection with chalk.
2. Set the gear selector to neutral.
3. Brake the vehicle with the parking brake.
4. Crank the crankshaft and at the same time inspect the condition of the belt drive making a full revolution.
5. Turn the shaft a few more times.
6. Check the outside of the part.

The belt needs to be replaced if found:

• signs of wear;
• cuts;
• porosity;
• bundles;
• traces of oil;
• ruffling.

In addition to an external examination, malfunctions are still possible in the form of an extraneous whistle at the maximum load of electrical circuits or when the warning lamp of the battery discharge comes on.

Preparing to replace the Chevrolet Niva alternator belt

The new part must be the same type and size as the worn drive. It is advisable not to be stingy and purchase a product of a well-known brand. Required tool:

• screwdriver;
• mount;
• jack;
• keys set.

It makes sense to disconnect the battery terminals to avoid accidental short circuits.

Chevrolet Niva Drive Gear Replacement Sequence

When everything is ready, you can start working. in this order:

1. Disconnect the crankshaft position sensor (CMP) connector.
2. Unscrew the sensor mounting bolt with a screwdriver and remove the device.
3. Unscrew the alternator mounting nut by 2-3 turns.
4. If necessary, unscrew the tensioner roller holder and slide it up.
5. Loosen the drive by moving the alternator towards the cylinder block.
6. Jack up the right front wheel.
7. Put direct gear on the gearbox.
8. Move the belt drive off the pump pulley in the direction of the radiator.
9. Rotate the jacked up wheel counterclockwise until the part is removed from the pulley.

Installation of a new drive occurs step by step:

1. Put the Chevrolet Niva alternator belt on the crankshaft pulleys, alternator and partially on the pump.
2. Rotate the wheel clockwise until it is installed.
3. If there is a tension roller, put it on and adjust its position.
4. Tighten the alternator nut.
5. Install and connect DPKV.

Gear Tension Adjustment Rules

It should be borne in mind that insufficient tension reduces the battery charge level and leads to wear on the mechanisms. At the same time, high tension can cause damage to the unit bearings. The optimal indicator of the belt deflection between the pulleys of the generator and pump is 10-15 mm with an applied force of 100 N (10 kgf).

The adjustment procedure is:

• if there is a tensioner, unscrew the bolt of its fastening and, by moving, achieve the desired results;
• in the absence of a roller, loosen the fastening of the alternator and adjust the deflection index, and then fix the unit.

After driving 500 km, check the gear tension level again and, if necessary, eliminate the non-compliance.

Replacing the alternator belt Niva Chevrolet not regulated by any numbers, but the manufacturer clearly stipulates the timing of checking the integrity of the drive belt. It is necessary to check the condition of the alternator belt every 15 thousand kilometers. If the belt is cracked, loose and oiled, it must be replaced. Another reason for replacement may be the “squeal” of the Chevrolet Niva slipping belt, which does not disappear even after adjusting the tension.

If your Chevrolet Niva has an air conditioner, then in order to get to the alternator belt you will have to remove the air conditioning compressor drive belt... To do this, we drive the car into a pit or overpass and remove the engine protection. We'll also have to remove the front mudguard by unscrewing the screws.

To remove the air conditioner belt on the Chevrolet Niva, loosen the tightening of the two bolts of the tension roller bracket and loosen the belt tension by rotating the adjusting bolt counterclockwise. We look at the picture below.

The weakened belt can be easily removed by hand.

After replacing the alternator belt, install the air conditioner belt in the reverse order and tension it. To check the belt tension, press with your finger on the belt in the middle between the compressor and crankshaft pulleys. With a pressing force of about 10 kgf, the belt deflection should be about 8.0 mm.

Now let's go back to replace the alternator belt Shnivy... To replace the belt, remove the rubber sleeves for the air supply to the throttle assembly. This will allow you to easily release the tension.

Then, with the "13" head, we loosen the tightening of the three nuts securing the tension roller bracket. Using a key or a "13" head, turn the adjusting bolt counterclockwise, loosening the belt. Remove the belt from the tension roller and other pulleys.

Install the new belt in the reverse order, putting it first on the crankshaft pulley, and lastly on the tension roller. After installation, adjust the belt tension. A diagram of the correct location of the drive belts in the following photo.

To check the belt tension, press your finger on the belt in the middle between the pulleys of the generator and the coolant pump. With a pressing force of about 8.0 kgf, the belt deflection should be about 12 mm. overtightening the belt does not bode well. Not only will the alternator belt wear out quickly, it will also shorten the life of the bearings of your Chevrolet Niva auxiliary units.

The first signs that a Chevrolet Niva alternator belt needs to be replaced can be heard even without much effort. The whistle from its slipping on the pulleys cannot be confused with anything. But if there is no desire to wait for the tug on the road, then it is advisable to periodically inspect the condition of the drive.

Transverse cracks in the material, both inside and outside, indicate the need for urgent replacement. The manufacturer recommends this procedure to be carried out every two years or after every 60 thousand km of run.

The belt of the Chevrolet Niva generator has a more accurate name - the drive belt for additional units, because in addition to the rotor, it drives the pulley of the water pump and the pulley of the power steering. Before work, you will need to prepare all the necessary tools. By the way, there are not so many of them:

Key for 10;
Key for 13;
Dynamometer;
Ruler.

The required drive tension is provided by a special roller with a movable bracket.

A dynamometer with a ruler is just used to correctly set the degree of its tension. Too low tension will lead to slippage, and strong tension will result in excessive wear of both the V-ribbed belt and the generator bearing.

Chevrolet Niva alternator belt replacement

It is necessary to start manipulations by loosening the roller (3). To do this, loosen the three nuts securing the bracket, and then turn the adjusting bolt (5) to achieve a state in which the belt is removed from the roller. Then it is removed from the pulleys in a random sequence.

Important!!! If the car is equipped with air conditioning, you will first have to remove the compressor drive belt by loosening the corresponding tensioner pulley.

Replacing the alternator belt is easy if you start from the crankshaft pulley and finish on the idler. The final of the manipulations is the tension check. Between the pulleys of the generator and the pump, press the belt with a force of 80 N. In this case, the deflection (h) should be equal to 12 mm. After 2 - 3 revolutions

In the article we will talk about changing the belts on the Chevrolet Niva. There are three of them - a gas distribution mechanism, an air conditioner and a generator. It is worth noting that the timing drive only on Opel engines has a belt drive. On other motors, it is chain. Therefore, in our article we will only consider the repairs on the "opelev" power units. It is also worth noting that the generator drive belt still rotates the pump pulley, power steering. The easiest way is to change the air conditioner belt, and let's start with it.

How to replace the air conditioner belt

In order to replace the air conditioner belt on the Chevrolet Niva, you need to use only one key for 12. There are no difficulties during repairs, it is enough to install the car on an inspection pit or overpass. It is much easier to make repairs this way, because the belt is located at the bottom. To remove it, you will need to loosen the roller mount. Thus, loosen the tension on the belt itself. Pay attention to the condition of the roller - it must rotate without jamming, otherwise it will need to be replaced.

After installing a new belt, it is enough to tension it using the bolt installed on the roller. Please note that when replacing all belts in a complex, this should be put last. First, replace the timing belt, then the generator, and lastly the air conditioner.

Removing the timing belt

When replacing the timing belt on the Chevrolet Niva, follow these steps.

1. Remove the air conditioning and cooling radiators completely. Before that, of course, you will have to drain the liquid from the cooling system and release the freon. There is no need to remove the fans from them.
2. Remove the air cleaning filter housing.
3. Remove the A / C compressor and generator drive belts. It is imperative to remove the tensioning mechanisms.
4. Remove the upper part of the timing cover.
5. Install the marks on the gears of the shafts. They must be the same. There is a notch on the engine crankcase, which must match the mark on the pulley.

Installing the pump and timing belt

Further instructions on how to change the belt on the Chevrolet Niva.

1. Unscrew the bolts and remove the crankshaft position sensor and the roller that tightens the timing belt. It often happens that the roller fixing does not lend itself, you have to knock it down with a chisel.
2. Remove the pump by unscrewing three bolts.
3. All surfaces must be cleaned, degreased and applied with a sealant. Then you can put in a new pump.
4. Install a new drive belt and rollers. Check if the marks on the camshafts and crankshafts match. This requires cranking the crankshaft several times.
5. All elements that were previously removed must be reinstalled.
6. Fill the cooling system with fluid.

In order to fill the air conditioning system with freon, you need to contact the service.

When to change the alternator drive belt

Now let's talk about how the belt is replaced on the Chevrolet Niva. There are no regulations regarding the alternator drive belt, but the manufacturer still indicates the time when the element should be inspected. So, a condition check should be carried out approximately every 15,000 km. It can be considered normal if the surface does not show cracks, traces of oil or antifreeze, excessive wear.

If a whistle appears when the load is turned on, this is the first sign that the device needs to be replaced. Of course, you should first try to tighten it to get rid of such a nuisance.

How to change the alternator belt

In the event that an air conditioner is installed on the car, you will have to remove the belt that drives the compressor. Replacing the belt on the Chevrolet Niva was described above. After installing the new alternator belt, install the air conditioner drive. As for the tension of the compressor drive, it is necessary that when pressed with a force of 10 kgf, it sags by no more than 8 mm. But do not tighten it too much, as this will lead to rapid wear of the bearings and belt grooves.

When replacing the rollers and the alternator belt on the Chevrolet Niva, you need to perform such manipulations.

1. Remove the sleeves that supply air to the throttle valve. This will provide tension relief.
2. Using the 13 head, loosen the tightening of the nuts that secure the tension roller bracket.
3. Turn the adjustment bolt counterclockwise with a head or a 13 wrench. This will loosen the alternator belt.
4. Remove the alternator belt from the tension pulley and pulleys.

The procedure is very simple and does not require deep knowledge. Installation is in the reverse order. First, put the belt on the crankshaft pulley, and lastly, wind it over the roller. When the element is installed, you can start adjusting.

Tension adjustment

In order to check the belt tension, you just need to press your finger on it approximately in the middle - between the gears of the coolant pump (pump) and the generator itself. If the force is 8 kgf, then the maximum deflection value should be no more than 12 mm. But you do not need to tighten it too much, as this will reduce the life of the bearings and belt. And not only the generator, but also other auxiliary devices. When replacing a belt roller on a Chevrolet Niva, it is important to follow the instructions and make the correct tension adjustment.
