The indicator arrow on the moving part of the tensioner should be between the two extreme marks on the stationary part of its body.
If the indicator arrow drops below the leftmost mark, then the belt is extremely worn and needs to be replaced.
The belt also needs to be replaced if cracks, tears, or detachments of rubber from the fabric base are detected on it.
To remove the accessory drive belt, loosen its tension.
Self-replacement
To independently remove worn parts and install new parts, you will need a standard set of tools and basic handling skills.

Part numbers
To buy a suitable part, you need to know its original catalog number or the part number of a replacement.
Belt
The Chevrolet Lacetti uses a belt with 6 longitudinal wedges on the inside. Its length is 1875 mm, width - 26 mm.
It is impossible to give an exact answer to the question of which belt is better, the original or a replacement. The fact is that the service life is significantly affected by 2 factors: operating conditions (sand and pebbles getting into the drive) and the absence of a plastic casing, like on the timing belt. Because of this, original parts can last 15,000 kilometers or, for example, 60,000.
Spare parts from Gates and Contitech are popular among owners due to their half the price and service life comparable to the service life of the original.

Which drive belt is best to choose for the Chevrolet Lacetti?
For the Chevrolet Laccheti there are different types of belts from well-known manufacturers:
- Mayle;
- Contitech;
- Gates;
- SWAG;
- Febi.
Official Chevrolet dealers recommend installing a drive consumable from Gates.
Gates drive belt benefits:
- Long service life under high loads;
- Does not deform under sudden temperature changes;
- High-quality material ensures precise tension;
- This belt is replaced every 60 thousand kilometers.
The Chevrolet manufacturer recommends an original belt. Marking - GM 96183108 Belt 6PK 1875.
Advantages of consumables marked GM 96183108 Belt 6PK 1875:
- Has automatic tension;
- Has a wear indicator.
An incorrectly tensioned drive belt will result in increased battery consumption. After only a week of such a malfunction and active use of the vehicle, the battery will run out and the number of volts will reach a minimum level: no more than 10V. Low voltage will not be enough to start the engine.
Replacing the drive belt in the Lacetti is carried out according to the instructions described below.
Additional Information
Experienced Chevrolet Lacetti drivers practice using the so-called belt spray. Periodic spray treatment of the alternator belt allows you to solve several problems at once:
- Removes oil film
- The rubber softens, which prevents cracks.
We must not forget that the timing belt . The Lacetti repair blog has a detailed review on the topic of replacing the timing belt .

Pump key
To turn the pump you need a 41 mm wrench. You can purchase a special key. He looks like this
Or cut a regular open-end wrench to 41
And weld a head or something similar to it.
But personally, I am for the first option. The cost of a key ranges from 70 to 200 UAH, depending on the manufacturer and the thickness of the metal.
They are very comfortable to work with
In general, turn the pump counterclockwise and remove the belt
Pay attention to the photo above. Only the left side of the belt is loosened, while the right side remains taut
This point will be useful to us when installing a new belt.
Unscrew the bolts of the camshaft pulleys. If you forgot to remove them in advance while the belt was still installed, then you need to fix the pulleys.
Important! Do not use nuts or bolts placed between pulleys for fixation. This will inevitably leave marks on the working surfaces of the pulleys
This damage will then destroy the belt, possibly causing it to break!
Important! It is not allowed to rotate the camshafts with the timing belt removed!
To hold the pulley, you can use special devices. I use shock absorber strut spring clamps.
We dismantle the pulleys.
Note. The pulleys are different. The left is different from the right. The left one simply does the job of turning the camshaft. And the right one still works with the camshaft position sensor. And there is a special ebb on it that acts as a mark for the sensor.
It is impossible to confuse the position of the pulley on the camshaft, since there is a hole on the pulley
And there is a special pin on the camshaft
Unscrew the two bolts securing the DPRV with a 10 mm socket and remove it
Use a 14 or 15 mm socket to unscrew the deflection roller
Using a 12 mm socket, unscrew the three bolts securing the tension roller and remove it
We unscrew the rear timing case mounting bolts in these places
And dismantle the casing
Everything is leaking oil due to the aluminum valve cover
We unscrew the pump mounting bolts and dismantle it
To dismantle the crankshaft pulley, simply unscrew the crankshaft bolt and remove the pulley
We inspect the pulley and, if there is the slightest defect, replace it with a new one.
We clean the pump seat very carefully. And we treat it with fine sandpaper so that there are no sagging or traces of corrosion.
Note. If you do not prepare this area perfectly, then the pump may become slightly misaligned. And this will lead to the fact that the belt may begin to slip off the pulleys while the engine is running!
The main nuances of the functioning of the timing belt in cars
It is extremely important to understand that the rubber timing element is responsible for transmitting the timing gear in the motor shafts. The latter, in turn, are responsible for the maintenance of the air-fuel mixture in the cylinders of the power unit
If the timing belt jumps or breaks, the entire timing belt system begins to function differently. All this is manifested by shifts and malfunctions of the most important component of the car - its engine. It was written in detail above that in these cases the power of the power plant necessarily decreases, fuel consumption increases and starting deteriorates.
In addition, slippage or rupture of the timing component can cause failure of the piston-valve group in the engine. When the belt breaks, the valves open towards the piston, which leads to internal engine problems.
Monitoring the condition of the timing belt is a guarantee of preventing severe consequences for the power plant
But it is important to be able to control not only the appearance of the belt, but also the degree of tension. On their own, which is quite natural, it will be extremely difficult for a person with non-professional skills to diagnose the correct installation of the belt
In order not to make a mistake, you need to pay attention to the service life of the belt and the condition of the parts accompanying the operation of the element. In particular, ensuring the degree of tension and uninterrupted operation
The period for replacing the most important timing part may vary. It depends on the specific car manufacturer. In addition, it is necessary to take into account such an indicator as the originality of the part. It is clear that “left” companies can easily produce defective belts or belts with a reduced service life.
It is also important to understand that on the modern market you quite often find parts of the universal type rather than the standard one. What does it mean? It's simple - universal parts, belts in this case, are not made for a specific car
They are not a priori characterized by good quality, and although they are cheaper than the original ones, they are not recommended for purchase.
You can distinguish an original belt from a universal one (there are several effective ways). If the part is universal, then to determine the service life of the belt and its replacement, you will have to take this into account. In other words, if the manufacturer indicated that the belt can last 70 thousand kilometers on his car, this does not apply to the universal one. This one will definitely last less.
As mentioned above, the service life of the belt on front-wheel drive VAZs is approximately 60-70 thousand kilometers. If the car was purchased secondhand, you should not trust its owner who claims that the belt is new, there will be no problems with it.
When choosing a new timing belt for your car, it is recommended to pay great attention to the material. If there are no marks left on the rubber after several folds in and out, most likely, everything is fine with the material
But on the contrary, if even the slightest microcracks are noticed, it is better not to buy such a belt right away.
It is also recommended to check the belt model number with the number specified in the operating manual for a specific vehicle. The numbers are unlikely to match; it is a great success if such a belt can be found. But you can check belts in another way: by comparing the length, width and thickness of the old factory belt and the new analogue.
The belt must also be checked around its entire circumference. If protruding threads are noticeable on the ribs, the cord will be visible, it is better to immediately abandon this option.
If you do not have the appropriate skills and ability to work with your own hands, it is better to entrust replacing the timing belt to professionals. Without a doubt, a seemingly simple operation at first glance can fray your nerves and take a lot of effort. And most importantly, an illiterate replacement can lead to even bigger problems.
Of course, in a big city it will be easier to find a quality car service among the many options. In rural areas, you have to rely on the honesty of service station workers or carry out this event yourself
The most important thing is that it doesn’t matter which method was chosen, what’s more important is to save time and money, getting the highest quality result
- Absolutely legal (Article 12.2);
- Hides from photo and video recording;
- Suitable for all cars;
- Works through the cigarette lighter connector;
