There are two main causes of cracking in glass: from mechanical stress and from a sudden change in temperature.
It’s easy to tell them apart:
A typical “thermal” crack. Mechanical damage that has caused cracks is not visible. This means that the extremely rapid change in temperature is to blame.
Is it possible to go to the service without a trip if a crack has appeared on the windshield? The expert “Behind the wheel” explains Alexey Revin.
To apply this technique, several conditions are necessary:
- The tightness of the glass should not be broken (both layers are not deformed);
- The defect is not near the wipers on the side of the steering wheel;
- The length of the crack does not exceed three centimeters and is located no closer than 5 cm from the edge of the glass.
You need a tubular diamond drill with a diameter of 4 millimeters. Through the guide plate, you need to drill the top layer of glass at the end of the crack to the film connecting the two layers. In addition, the screwdriver should work at low speeds.
The resulting hole will reduce pressure on the crack and stop it from propagating. However, you need to be even more careful to avoid temperature fluctuations, because such glass is much more sensitive than before. In a car repair shop, they can take 1300-3700 rubles for such work. But it’s best to replace the glass, Aleksey Revin is sure.
