Running a car without coolant will prevent the coolant from circulating properly, causing the engine to overheat due to inadequate cooling. In severe cases, this can lead to engine damage. Functions of coolant: Coolant is a special additive-containing fluid primarily used in liquid-cooled engine cooling systems. It provides excellent performance in preventing freezing in winter, boiling in summer, and resisting scale and corrosion year-round. Can different coolants be mixed? It is necessary to use the same brand of coolant. Different brands of coolant may have varying production formulas, and mixing them could cause chemical reactions between additives, rendering them ineffective. How to choose coolant: The basic indicators for coolant are its freezing and boiling points. Market-available coolants come in specifications like -15°C, -25°C, -30°C, and -40°C freezing points. Generally, it's advisable to choose a coolant with a freezing point at least 10°C lower than the lowest temperature in your region. How to choose coolant: Generally, it's advisable to choose a coolant with a freezing point at least 10°C lower than the lowest temperature in your region.

Is a Car with Deployed Airbags Still Worth Keeping?

Airbags deployed in a car does not necessarily mean it cannot be kept. As long as the body structure and engine are unaffected, there is no issue at all. Function of Airbags: The airbag system is a passive safety (see vehicle safety performance) protection system. When used in conjunction with seat belts, it provides effective collision protection for occupants. Structure of Airbags: Airbags mainly consist of several components including impact sensors, an electronic processor, an inflation device, and the airbag itself. The airbag is made of high-strength fabric, typically a special woven nylon with a rubber lining, and is mostly concealed within the steering wheel, dashboard, door frame, and seats.

In which seasons are 15w40 and 20w50 engine oils used?

15w40 and 20w50 engine oils are both all-season oils, but since the minimum applicable temperature for these oils is -15 degrees Celsius, they cannot be used in certain regions during specific periods. The 'S' prefix denotes gasoline engine oils: Specifications include SA, SB, SC, SD, SE, SF, SG, SH, SJ, SL. The 'C' prefix denotes diesel engine oils: Specifications include CA, CB, CC, CD, CE, CF, CF-2, CF-4, CG-4, CH-4, CI-4. Oils with both 'S' and 'C' letters are universal for both gasoline and diesel engines.

What is the difference between China VI and China V vehicle emission standards?

The distinction between China V and China VI vehicle emission standards can be identified by the letter designation on the vehicle's rear: China V is represented by 'V', while China VI is represented by 'VI'. The differences between the two standards are as follows: Different emission standards: China VI standards are more than 30% stricter than China V. Excluding the influence of operating conditions and testing, gasoline vehicles under China VI must reduce carbon monoxide emissions by 50%, total hydrocarbons and non-methane hydrocarbons by 50%, and nitrogen oxide emissions by 42% compared to China V. Different implementation times: The China V standard was implemented nationwide on January 1, 2017, as the fifth stage of national motor vehicle emission standards. The China VI standard has been in effect since July 1, 2019. Different principles: Under China V, diesel and gasoline vehicles had different emission standards. However, China VI adopts a fuel-neutral principle, meaning the emission limits are the same regardless of the fuel type. Different issuing authorities: The China V standard was issued by the Ministry of Environmental Protection, while the China VI standard was jointly issued by the Ministry of Environmental Protection and the General Administration of Quality Supervision, Inspection, and Quarantine. Different letter designations: China V is represented by 'V', while China VI is represented by 'VI'. Different monitoring requirements for plug-in hybrid electric vehicles (PHEVs): Compared to China V, China VI has enhanced monitoring requirements for PHEVs, including energy storage systems, thermal management systems, regenerative braking, drive motors, generators, and other regulatory aspects. China V emission limits are as follows: Gasoline vehicles must not emit more than 1,000 mg of carbon monoxide per kilometer driven. Non-methane hydrocarbon emissions must not exceed 68 mg per kilometer. Nitrogen oxide emissions must not exceed 60 mg per kilometer. PM (particulate matter) emissions must not exceed 4.5 mg per kilometer. China VI has two sub-standards: China VIa and China VIb, with the following limits: China VIa emission limits: Gasoline vehicles must not emit more than 700 mg of carbon monoxide per kilometer driven. Non-methane hydrocarbon emissions must not exceed 68 mg per kilometer. Nitrogen oxide emissions must not exceed 60 mg per kilometer. PM emissions must not exceed 4.5 mg per kilometer. China VIb emission limits: Gasoline vehicles must not emit more than 500 mg of carbon monoxide per kilometer driven. Non-methane hydrocarbon emissions must not exceed 35 mg per kilometer. Nitrogen oxide emissions must not exceed 35 mg per kilometer. PM emissions must not exceed 3 mg per kilometer. Affected by the China VI emission policy, although China V vehicles are not currently restricted in normal use (no driving bans or plate restrictions), their resale value is significantly impacted. For truck owners, if they purchase a truck on loan for hauling goods, the vehicle's depreciation after paying off the loan is equivalent to the net profit earned during that period. A higher residual value means more profit for the owner. From this perspective, China VI vehicles, which have a longer service life and more road privileges, offer greater advantages.

What does the yellow half-circle exclamation mark light on the car mean?

Dashboard indicator light with a yellow half-circle exclamation mark typically indicates low tire pressure. Door status indicator light: This light shows whether the doors are fully closed. It illuminates when a door is open or not properly closed, alerting the driver that a door is ajar, and turns off when the door is closed. Parking brake indicator light: This light turns on when the parking brake handle (i.e., handbrake) is engaged. It automatically turns off when the handbrake is released. In some car models, this light may also illuminate when the brake fluid level is low. Battery indicator light: This light displays the working status of the battery. It lights up when the ignition is turned on and turns off after the engine starts. If it does not light up or remains lit continuously, the generator and circuit should be checked immediately.

Why don't many cars come with heated mirrors?

Many cars don't come with heated mirrors because this feature is only frequently used during rainy days and is rarely needed otherwise, so it's not installed. Function of heated mirrors: Heated mirrors refer to the feature where, when driving in rain, snow, fog, or other adverse weather conditions, the mirrors can be heated via electric heating wires embedded behind the mirror surface to ensure clear visibility. How to use heated mirrors: In rainy or snowy weather, the driver simply needs to press the defrost button, and the mirrors will heat up (typically between 35 to 60 degrees Celsius), removing fog or frost buildup on the mirror surface. This not only provides convenience but also enhances driving safety.
