In summer, the normal tire pressure for cars ranges between 2.3-2.5. If the car is fully loaded with 5 passengers, it's more suitable to adjust the tire pressure to around 2.5; for general use with two passengers, a tire pressure of 2.3 is normal. Relevant details are as follows: 1. Tire maintenance: Proper tire pressure is the most important aspect of tire maintenance. The standard tire pressure depends on the vehicle it's installed on, which is the pressure indicated on the vehicle's door or fuel tank cap. This is the standard value determined by the vehicle manufacturer during design and manufacturing to achieve optimal performance, generally allowing a difference within 10%. If it's below the standard value by more than 10%, it's considered underinflated; if it's below the standard value by 20%, you should visit a professional shop as soon as possible to check for any damage or air leakage. 2. Consequences of abnormal tire pressure: Overinflated tires reduce the contact area with the ground, increasing the pressure and wear per unit area, which can easily lead to loss of braking control, bursting when encountering ground protrusions or depressions, damaging the vehicle's suspension system, and causing discomfort during rides. Underinflated tires increase the contact area with the ground, causing abnormal increases in tire temperature during driving. Additionally, severe deformation of the tire side accelerates the aging of internal steel wires and fabric layers, creating hidden dangers for tire bursts, increasing fuel consumption, and reducing tire lifespan.

When to Replace Antifreeze?

Antifreeze should be replaced every 2 years or 60,000 kilometers. The full name of antifreeze is antifreeze coolant, which is a type of coolant containing special additives. It is mainly used in liquid-cooled engine cooling systems to prevent the coolant from freezing and cracking the radiator or damaging the engine cylinder block or head when the vehicle is parked in cold winter. Antifreeze contains: calcium chloride, methanol, ethanol, ethylene glycol, and glycerin. The method to replace antifreeze is: 1. Open the hood after the engine has cooled down; 2. Open the antifreeze reservoir cap; 3. Lift the vehicle and open the radiator drain plug, drain the old antifreeze, then reinstall the drain plug; 4. Lower the vehicle and pour new antifreeze into the antifreeze reservoir.

What does Guolv represent?

Guolv represents China IV (National IV emission standard). Guolv is set based on the compatibility of vehicle engine systems and emission standard tests, belonging to transitional vehicle models. The sulfur content limit for China IV standard gasoline is 150 milligrams per kilogram. Currently, light-duty diesel vehicles implement the third-stage emission standard, while light-duty gasoline vehicles implement the fourth-stage emission standard. The China IV emission standard is the national fourth-stage motor vehicle pollutant emission standard. The main pollutants emitted by vehicles include hydrocarbons, nitrogen oxides, carbon monoxide, and particulate matter. Through the application of technologies such as improved catalytic converter active layers, secondary air injection, and exhaust gas recirculation systems with cooling devices, the standard controls and reduces vehicle emissions to below specified levels.

How to Identify the Quality of Car Window Tint?

Methods to identify the quality of car window tint are as follows: 1. Touch. Low-quality films use ordinary polyester film as the base material. Due to their loose internal structure, they are prone to dyeing, have low strength, lack elasticity and toughness, and are easily wrinkled, failing to meet the basic requirements of safety and explosion-proof films for cars. In contrast, high-quality films use optical-grade polyester film, which is not only more expensive but also feels thick, smooth, dense in structure, and high in strength, offering superior safety and explosion-proof performance. 2. Color. Low-quality films mainly rely on dyeing processes, causing the pigments to adhere to the surface of the film. This results in poor color uniformity and stability, severe color deviation, and a tendency to fade and blur. High-quality films, however, are manufactured using magnetron sputtering technology, which adsorbs precious and rare space metal atoms such as gold, silver, nickel, and titanium through a strong magnetic field. These films not only have uniform color but also naturally exhibit space metal hues, high visual clarity, and excellent transparency, making them highly suitable for car windshields. 3. Scratch Resistance. Low-quality films lack a scratch-resistant layer on the surface, making them prone to scratches when rolling windows up and down or wiping by hand. If lightly wiped with alcohol or gasoline for a minute, low-quality films will show signs of fading. High-quality films, on the other hand, feature a professional scratch-resistant layer, making them more resistant to scratches and less likely to be damaged. Even when lightly wiped with alcohol or gasoline, they do not discolor.

What Causes White Smoke from the Car's Exhaust Pipe?

Car exhaust pipe emits white smoke for the following reasons: Water vapor cause: White smoke from the exhaust pipe is water vapor being expelled. Cylinder head gasket damage: If the coolant level in the radiator decreases, it indicates damage to the engine cooling water passage or cylinder head gasket, causing coolant to enter the cylinder and burn. Water in the exhaust pipe: If the coolant level is not low, water may have entered the exhaust pipe due to rain or car washing. White smoke from the exhaust pipe is definitely abnormal. It is best to diagnose the cause, otherwise long-term emission of water vapor can corrode the exhaust pipe, leading to premature rust and damage.

What Causes the Valve Failure in Skoda Octavia?

The reasons for valve failure in Skoda Octavia: 1. Poor valve sealing: When the car's valves fail to close properly, it leads to valve leakage; 2. Valve spring fatigue: If the issue of a broken valve spring occurs in an older vehicle, it may be due to prolonged use causing the valve spring to age or wear out, resulting in fatigue fracture; 3. Engine throttle usage: Frequent fluctuations in engine speed can significantly increase the risk of valve spring breakage during vehicle operation. The Skoda Octavia is a compact car with a 5-door, 5-seat hatchback body structure. Its dimensions are 4659mm in length, 1814mm in width, and 1460mm in height, with a wheelbase of 2686mm.

How often is it normal for a car air conditioner to cycle on and off?

It is normal for a car air conditioner to cycle on and off approximately every 30 seconds. A car air conditioner is a unit used to provide air temperature changes in a space area (usually enclosed) to meet the requirements of human comfort or process conditions. The car air conditioner consists of a refrigeration system, heating system, air purification device, and control system, which are used to adjust and control the temperature, humidity, air cleanliness, and air flow inside the car compartment to an optimal state. The car air conditioner compressor is located in the engine compartment and is the "heart" of the car air conditioning refrigeration system, playing the role of compressing and transporting refrigerant vapor.
