The front windshield of a truck is commonly divided into two types: tempered safety glass and laminated safety glass. The price of tempered safety glass is slightly lower than that of laminated safety glass because after being shattered, tempered glass breaks into small particles without sharp edges similar to those of a glass knife, which is why it is widely used in car windshields. However, tempered safety glass does have some harmfulness; many drivers encounter the phenomenon of summer glass explosion, where splashing fragments can cause injuries, often cutting arms and heads. Another less noticed hazard is that broken glass residue enters the air conditioning outlet through the hot water tank, air conditioning evaporator box, and fan blades. Subsequent issues such as water leakage, refrigerant leakage, and blade damage are often difficult to resolve.
What measures can be taken to solve this? Besides replacing with safer laminated glass, we can also apply a film to the glass to address the issue. Many drivers may have misconceptions about applying a film to the windshield. In fact, transparent films specifically designed for front windshields have been widely used domestically and internationally for a long time.
Here are the benefits of applying a film to the front windshield:
1. The front windshield is the main source of heat radiation that raises the temperature inside the car. After installing the transparent film, the driving environment inside the car can be significantly improved.
2. After applying the film to the windshield, it effectively blocks UV rays, protecting the dashboard from radiation and extending its lifespan while preventing the driver from getting tanned.
3. For tempered safety glass, if it shatters after the film has been applied, the fragments won't fly around, ensuring the safety of the driver.
4. In winter, the glass is less likely to fog up, and the fatigue caused by the headlights of oncoming vehicles at night can be somewhat alleviated.
However, it should also be noted that after applying the film to the front windshield, items cannot be placed near the dashboard. When cleaning the glass, chemical solvents cannot be used; instead, a neutral cleaning agent solution can be used. As summer approaches, I would like to remind everyone not to obstruct the view and to choose colorless and transparent car films to protect our windshields.
Hello: According to your vehicle operation situation, it is not related to the first maintenance. Based on your vehicle driving conditions during normal driving, if the engine speed is obviously too high, I wonder if you are in the break-in period or normal driving. For manual transmission models, the general normal shift timing is around 2100~2300 RPM. Therefore, I suggest you control the shift timing and observe again. You can also judge based on the actual operation feeling. If you feel the engine lacks power after shifting gears, then the shift was definitely too early. When the car still has momentum after shifting gears and can reach this effect at the lowest speed, then that speed is the optimal shift speed for the entire vehicle.
