One of the conditions for the longevity of the belt is the proper condition of the rollers and pulleys. The element itself must be properly tensioned.

The product is based on fiberglass cord. Inside the cord, teeth are made of materials that are resistant to wear - most often it is nylon. Outside, this entire structure is protected by a layer of rubber up to 5 millimeters thick. Timing belts can have a variety of designs depending on specific manufacturers. The product may differ in width, number, pitch, tooth profile.

Replacement cost

It is customary to change the elements of the gas distribution mechanism at the service station. The price of replacing the Lacetti timing belt can fluctuate on average from 3 to 5 thousand rubles. For self-replacement, you will need to purchase a spare parts kit.

Sometimes the belt rubber peels off. This is a clear sign of wear. It is recommended to inspect the back as well as the front surface of the product. If cracks are present, the part is heavily worn.

The hardened opposite surface of the part also speaks of the need for replacement. It loses its elasticity and shine. In this case, the belt loses its flexibility and does not provide proper contact with the pulleys.

Timing belts tend to lengthen. As a result, the tension roller moves. This results in reduced stiffness and overall belt tension.

On the need to replace the whole set

Next, dismantle the bodyair filter and you can remove the drive belt. Below, a suitable support is installed under the motor and the right support is unscrewed. The last one needs to be put aside.

Next, dismantle the upper plastic belt guard, and then the lower one. The engine is turned by the camshaft bolt until the marks match. On the camshaft gears, both marks should be opposite each other. The mark on the crankshaft gear should point down.

The belt on this engine is tensioned by moving the pump housing. Turn the pump to loosen the belt. If the pump is also changing, then it is dismantled along with the belt and parasitic roller.

Then install a new belt. It is important to pay attention to the arrows that indicate the direction of movement of the belt. They should point to the right. When mounting the belt on the contrary, it can wear out intensively. Before installing a new one, it is better to check the labels again. It is convenient to tighten the belt with a 41 key, but it is not very convenient. It is better to purchase a special key.

In the process of tensioning the belt, the pump is rotated so that the marks on the tension roller are aligned. After tensioning the belt, you need to check the correct installation - the engine is scrolled two turns and the marks are looked.

This completes the replacement of the Lacetti timing belt by hand in the garage. Engine covers and engine brackets can be reinstalled.

Lacetti 1, 6

This engine differs from 1, 4 only in volume. As for everything else, it is completely similar to the smallerunit. Therefore, the process of replacing the belt is also similar. It makes no sense to describe the order of work.

I must say that to replace the timing belt "Lacetti" 1, 6, a belt from an internal combustion engine of 1.4 liters is suitable. Both belts have 127 teeth, both are 1210 mm long and 25 mm wide. On a 1.8 engine, the belt is different - here the number of teeth is 162. A belt from Aveo after 2005, a belt from Nubira, Cruze and Nexia is also suitable. The manufacturer can be any, but frank China is not worth buying. Cheap belts last no more than 30 thousand kilometers and break at the most inopportune moment.
