What Are the Common Car Maintenance Tips for Summer?

Eight essential car maintenance tips for summer: 1. Thoroughly clean the air conditioning system: It's crucial to perform a complete cleaning and disinfection of the car's AC pipes during summer, as the system will be in constant use. 2. Deep clean and sanitize the interior: Due to the summer heat, many drivers keep windows closed and rely heavily on recirculated air, leading to poor air quality inside the cabin. High humidity before thunderstorms can also encourage bacterial growth. Consider using interior cleaners or visiting a car detailing shop for a thorough interior cleaning. 3. Don't overlook antifreeze: Coolant evaporates faster in summer, so regularly check levels and top up with the same brand of antifreeze—avoid mixing brands or using water. 4. Engine oil: Opt for higher viscosity oil in hot weather, as elevated engine temperatures can thin the oil, accelerating oxidation. 5. Brakes: Summer often brings rain, reducing friction between tires and wet roads—especially when treads are waterlogged. 6. Prevent spontaneous combustion: Older vehicles are particularly prone to electrical fires in summer due to aging wiring and fuel lines. Have your car's electrical system inspected, and replace any worn components immediately. 7. Protect your paint: Park in shaded areas whenever possible. Prolonged sun exposure can fade and damage paint. While waxing helps, most waxes contain silicon that can react with UV rays, causing rust spots. 8. Avoid tire blowouts: High road temperatures make regular tire pressure checks essential. Underinflated tires generate excessive heat, potentially melting internal rubber layers and causing tread separation—a major safety hazard.

What are the disadvantages of car ozone disinfection?

Ozone is a strong oxidizing agent that can damage various items. The higher the concentration, the more severe the damage to items. It can cause green rust spots on copper sheets, aging, discoloration, and reduced elasticity of rubber, leading to brittleness and breakage, as well as bleaching and fading of fabrics. Ozone also irritates the mucous membranes of the human respiratory tract. At concentrations of 0.5-1 ppm, it can cause discomfort such as dry mouth. Therefore, ozone disinfection must be conducted in the absence of people, and entry should be avoided for at least 30 minutes after disinfection. More details are as follows: 1. According to international standards, concentrations of 0.5-1 ppm can cause discomfort such as dry mouth; 1-4 ppm can cause coughing; and 4-10 ppm can cause severe coughing. 2. Ozone disinfection is an allotrope of oxygen, gaseous at room temperature, highly reactive chemically, very soluble in water, and has extremely strong oxidizing capabilities. 3. The oxidizing power of ozone can be used for sterilization and disinfection. When ozone encounters bacteria, it immediately undergoes an oxidation reaction, thereby achieving functions such as sterilization, mold removal, odor elimination, and decomposition of harmful gases. The oxygen left after the reaction does not pollute any items in the car. 4. The ozone sterilization and disinfection process takes 15 to 30 minutes. After completion, the car owner should not enter the vehicle immediately but should leave the doors open for a few minutes to allow any remaining ozone to fully react before entering. Due to its strong oxidizing properties, ozone can pose certain hazards to human health.

Can the battery be charged while the vehicle is idling?

Vehicle can charge the battery while idling, and it takes about 20 minutes to fully charge. Car idling is to overcome the engine's own operating resistance, maintain engine speed, and make it more convenient for drivers during driving and temporary parking. The functions of car battery include: 1. Providing power for the car's starter and ignition system; 2. Providing stable DC power for car electrical appliances. Precautions for charging while the vehicle is idling are: 1. Check whether the charger is 12V, 24V dual-use. If there is only one battery, a 24V charger cannot be used for charging; 2. For water-added batteries, the cover needs to be opened during charging, while maintenance-free batteries can be charged directly.

What are the precautions for car maintenance in winter?

Precautions for car maintenance in winter include: 1. Timely replacement or addition of antifreeze; 2. Changing the windshield washer fluid in advance; 3. Checking if the engine oil is sufficient; 4. Adjusting the tire pressure; 5. Paying attention to the battery inspection; 6. Taking care of the car body and chassis; 7. Promptly checking if all the car lights are functioning properly. The purpose of car maintenance is to filter impurities from the engine oil and gasoline, preventing them from entering the engine and affecting its normal operation. Regularly replacing these components can effectively extend the engine's service life, keep the car clean and tidy, ensure normal technical conditions, eliminate potential hazards, prevent faults, and slow down the deterioration process.
