Do I Need to Dilute Windshield Washer Fluid with Water?

Vehicle windshield washer fluid needs to be diluted with water. The method for adding windshield washer fluid is: 1. Open the hood and locate the windshield washer fluid filler port; 2. Remove the cap and pour the windshield washer fluid into the reservoir; 3. Observe the liquid level until it reaches the marked line. The functions of windshield washer fluid are: 1. Cleaning performance; 2. Antifreeze performance - the presence of alcohol and ethylene glycol significantly lowers the freezing point of the liquid; 3. Anti-fog performance - forms a monomolecular protective layer on the surface to prevent fog droplet formation, ensuring clear windshield visibility; 4. Lubrication performance - the high viscosity of ethylene glycol provides lubrication, reducing friction between wipers and glass to prevent scratches.

Why is the Low-Pressure Pipe of a Car Air Conditioner Hot to the Touch?

Causes for the low-pressure pipe of a car air conditioner being hot to the touch include compressor or expansion valve failure, evaporator blockage, insufficient refrigerant flow, or excessive pipeline pressure, as well as excessive fouling in the condenser copper tubes. Under normal circumstances, the low-pressure pipe of a car air conditioner should be cool, while the high-pressure pipe should be hot. If the low-pressure pipe becomes hot, the air conditioning cooling effect will be poor. Below is additional information: 1. Compressor or expansion valve failure: This can cause the low-pressure pipe of a car air conditioner to become hot. The air conditioner compressor plays a role in compressing and driving the refrigerant in the air conditioning refrigerant circuit. The air conditioner compressor extracts the refrigerant from the low-pressure area, compresses it, and sends it to the high-pressure area for cooling and condensation. The heat is dissipated into the air through the radiator, and the refrigerant changes from a gaseous state to a liquid state, with an increase in pressure. 2. Checking the refrigerant: If the expansion valve is blocked and the air conditioner is not working, check whether the refrigerant is sufficient. If it is insufficient, the system needs to be vacuumed before adding refrigerant, and then use a pressure gauge to check whether the pressure in the high and low-pressure pipelines is normal. 3. Identifying the high and low-pressure pipes of a car air conditioner: The thin one is the high-pressure intake pipe, and the thick one is the low-pressure pipe. You can also distinguish them by the letters next to the compressor connection. Some compressors are mostly marked with S or D to distinguish them, where S is the low-pressure connection and D is the high-pressure connection.

What are the methods for choosing automotive explosion-proof film?

Automotive explosion-proof film should be selected based on the following methods: choose a film with good light transmission that does not obstruct visibility. The functions of explosion-proof film include: 1. Heat insulation and cooling: It can reduce the overheating phenomenon inside the car caused by sunlight exposure, keeping the interior cool while also reducing air conditioning consumption; 2. UV protection: While ultraviolet radiation has sterilizing effects, it can also harm human skin. Explosion-proof film effectively blocks UV rays, protecting passengers' skin; 3. Preventing glass cracking and interior fading: Besides harming the owner's skin, prolonged direct sunlight can cause the car's interior to crack and fade. Explosion-proof film also helps maintain the car's interior and prolong its service life.

What is the difference between tire pressure monitoring and tire pressure warning?

The difference between tire pressure monitoring and tire pressure warning lies in their detection methods: tire pressure monitoring employs active detection, while tire pressure warning utilizes passive detection. The hazards of excessive tire pressure include: 1. Reduced tire friction and adhesion, affecting braking performance and tire lifespan; 2. Decreased puncture resistance, increasing the risk of tire blowouts; 3. Accelerated wear on the central tread pattern, shortening tire life, increasing vehicle vibration, and impacting other component longevity; 4. Overextension of tire cords leading to reduced elasticity, increasing driving load and decreasing puncture resistance; 5. Increased susceptibility to punctures from road debris like nails or glass, potentially causing internal cracks, bursts, and blowouts.

What is the method to check the transmission oil level in a Volkswagen CC?

To check the transmission oil level in a Volkswagen CC, follow these steps: 1. Preheat the oil to approximately 50 degrees Celsius. 2. Shift the gear lever through each position, pausing for a few seconds in each gear, then check the oil level using the dipstick located on top of the transmission. The functions of transmission oil are: 1. To keep the shifting system clean; 2. To lubricate the transmission components. Taking the 2021 Volkswagen CC as an example, it is a mid-size sedan with the following dimensions: length 4865mm, width 1870mm, height 1459mm, wheelbase 2841mm, fuel tank capacity 66 liters, trunk capacity 501 liters, and curb weight 1640kg.
