Should You Apply Film to a Car Sunroof?

1 Answers

Generally, it is not recommended to apply film to a car sunroof. Here are the reasons why: 1. The sunroof glass usually already has UV protection and heat insulation functions. Applying film again would not only cause a certain degree of resource waste but also affect the overall quality of the vehicle. 2. After applying film to the sunroof, the overall thickness of the glass increases. If the installation is not done properly, it may lead to difficulties in opening and closing the sunroof. However, during hot summers, if the car is parked outdoors for a while, the sunroof area, being a weak spot for heat insulation on the roof, can cause the interior temperature to rise. If the decorative panel under the sunroof is opened, more heat will enter the car through the sunroof. Therefore, for large panoramic sunroofs, applying film may be considered depending on the regional climate and season. But not all panoramic sunroofs are suitable for film application. If the sunroof is made of colored heat-absorbing glass, dark-colored film should not be applied.

What to Do When the Vehicle License is About to Expire?

According to the laws and regulations of the traffic management authorities, if the vehicle owner fails to participate in the annual inspection after the vehicle's inspection period expires, the insurance company will not bear the liability for compensation in the event of a traffic accident. According to the provisions of the vehicle insurance contract, the scope of claims only applies to qualified and legal vehicles. For vehicles that have not undergone the annual inspection on time, no claims will be made in the event of a traffic accident. Additionally, if a vehicle that has not undergone the annual inspection on time is lost, the insurance company will also refuse to compensate. According to the "Road Traffic Safety Law," failing to participate in the annual inspection after the vehicle's inspection period expires is considered an illegal act. The driver will be fined 200 yuan for the violation, have 3 points deducted from their driver's license, and have their motor vehicle temporarily impounded.

Why does the car air conditioner not cool at idle but cools when accelerating?

There are several reasons why a car air conditioner may not cool at idle but cools when accelerating, including a damaged expansion valve, internal wear of the air conditioning compressor, and excessively low idle speed. Below are detailed explanations for each cause: Damaged expansion valve: This prevents the formation of high pressure in the system before the expansion valve, causing the high-pressure refrigerant to fail to reach the required 150Kpa pressure. As a result, the evaporator after the expansion valve cannot cool down, leading to inadequate cooling from the air conditioner. Internal wear of the air conditioning compressor: This results in the pressure between the air conditioning compressor and the expansion valve not reaching the required 150Kpa to 200Kpa, preventing the refrigerant in the system from circulating normally and causing the air conditioner to not cool properly. Excessively low idle speed: The car's onboard computer determines that turning on the air conditioner at this time could cause the engine to stall.

What are the reasons and solutions for the Passat's air conditioning not cooling?

Passat's air conditioning not cooling reasons include dust on the condenser coil and long-term closure of the internal circulation switch. Below are detailed explanations regarding the Passat's air conditioning not cooling: Dust on the condenser coil: The condenser coil behind the front grille is covered with dust, leading to poor cooling performance. In this case, the owner can resolve the issue by rinsing the dust off the condenser coil with a water hose during car washing. Long-term closure of the internal circulation switch: The internal circulation switch is closed, resulting in reduced cooling efficiency. There is a button on the dashboard with a car icon and a U-shaped arrow next to it, which is the internal circulation switch. If the owner accidentally turns off the internal circulation switch, it means the air conditioning enters external circulation mode, allowing outside air to enter.

Can the car be driven if the belt is broken and the water temperature is high?

Do not continue driving. Pull over and contact a towing service to take the vehicle to a repair shop. Below are the reasons for repair: Overheating water temperature: When the water temperature is too high, the viscosity of the engine oil becomes thinner, reducing lubrication strength. At the same time, high-speed moving parts such as pistons and valves are more prone to deformation, leading to a loss of engine power. In severe cases, the expanding pistons can scratch the cylinder walls, and the crankshaft bearings may melt and seize, resulting in unimaginable consequences. Belt breakage: During normal driving, if the engine belt breaks, the car will stall and become unusable. Additionally, the brake and power steering pump will stop working, posing a certain danger. If the timing belt breaks, the coordination between the pistons and valves will be disrupted, potentially causing the pistons to damage the valves. The repair costs in such cases can be quite high.
