Antifreeze of different colors cannot be mixed, as their chemical properties and compositions may vary. Even if the main ingredients are the same, the secondary components and formulation ratios can differ. Mixing multiple chemical components may trigger reactions, causing the antifreeze to lose its original properties. Antifreeze is a coolant containing special additives, primarily used in liquid-cooled engine cooling systems. It offers excellent performance in preventing freezing in winter, boiling in summer, and resisting scale and corrosion year-round. The chemical composition of antifreeze: over 95% of domestic and international antifreeze products are water-based ethylene glycol solutions. Compared to tap water, ethylene glycol excels in freeze protection, high boiling point, low volatility, moderate viscosity with minimal temperature variation, and excellent thermal stability, making it an ideal coolant.

What Are the Effects of Excessive Engine Oil Temperature?

Excessive engine oil temperature has the following effects: Impact on Lubrication: Excessively high temperatures cause the oil film to thin, increasing friction and accelerating engine wear. At the same time, internal engine components, including metal and rubber parts, will over-expand. Rubber aging accelerates and may even fail directly, while metal components may experience excessive pressure and damage. Furthermore, if the temperature exceeds the boiling point of the coolant, the engine may overheat, leading to coolant evaporation and the formation of vapor in the engine compartment, significantly reducing cooling efficiency and causing the engine temperature to rise even faster. Engine Shutdown: When the engine temperature is too high, some vehicles may automatically shut down the engine. If the issue is less severe, an alarm may sound. In such cases, the driver should also manually turn off the engine to avoid further damage, as excessive temperature poses multiple risks to the vehicle.

Should I Replace Two Tires First?

If conditions permit, it is better to replace all four tires. Generally, as long as tire rotation is performed regularly on the same vehicle, the wear levels of the tires will be similar. If one tire is no longer usable, the others are likely in a similar condition. Below is relevant information about tires: 1. Service Life: Tires have a service life, with a maximum usage period of 5 years. Beyond five years, the risk of tire blowouts increases significantly. Therefore, even if some tires still have good tread patterns, they should be replaced entirely after 5 years. 2. Car Tire Usage Notes: Every car tire has several raised wear indicators in the drainage grooves. When the tire wear reaches the level of these indicators, it means the tire should be replaced. When checking the tire wear limit, you will find that, under normal circumstances, front tires wear more severely than rear tires. When front tires need replacement due to wear, rear tires may still seem usable for several more years.

Can I Claim Insurance for a Second-Hand Car Without Transferring the Policy?

Insurance claims cannot be made for a second-hand car without transferring the policy. Below is an introduction to car insurance claims: 1. Overview: Car insurance claims refer to the process where the car owner files a claim with the insurance company after a traffic accident. The basic workflow of a claim includes steps such as reporting the incident, damage assessment, signing and receiving claim documents, calculation and review, approval, and final settlement. 2. Characteristics: Public nature of the insured: In China, car insurance policyholders were primarily companies and enterprises in the past. However, with the increase in personal car ownership, the proportion of individual car owners among the insured is gradually rising. These policyholders often purchase insurance passively and, due to limitations in culture, knowledge, and education, have limited understanding of insurance, traffic accident handling, and vehicle repairs. On the other hand, driven by interests, there can be significant communication barriers between inspectors, claim processors, and the insured during the claim process.

How Common Is It for Cars to Be Hit by Stones on the Highway?

It is quite common because the high speed of vehicles on the highway makes them susceptible to being hit by flying stones. Here are some additional precautions for driving on the highway: 1. Pre-trip vehicle inspection: Before driving, the driver should conduct a comprehensive check of the vehicle, with particular attention to various fluids, tires, and the braking system. 2. Adjust the rearview mirrors: When the rearview mirrors are in the optimal position, they allow the driver to better observe the sides and rear of the vehicle. Note that the adjustment methods for the left and right mirrors are slightly different. 3. Adjust the seat: A proper seating position can help the driver reduce fatigue during long-distance high-speed driving and ensure that the seating posture does not hinder the handling of emergencies. 4. Check the onboard tools: Onboard tools may rarely be used in daily driving, but they can be very useful in emergencies. 5. Pay attention to highway entrances: There are very strict requirements when entering the highway entrance ramp, including prohibitions on overtaking, making U-turns, stopping, and reversing.
