What is the function of automotive antifreeze?

During vehicle operation, the engine operates at high temperatures. If the engine continues to work under high temperatures, it can lead to damage or even complete failure in a very short time. Automotive antifreeze is added to the cooling system, where the engine's heat is transferred through the cooling system, reducing the temperature before dissipating it into the surroundings, thereby providing a cooling effect and preventing overheating. Relevant information about antifreeze is as follows: 1. Introduction: The full name of antifreeze should be antifreeze coolant, meaning a coolant with antifreeze properties. Antifreeze prevents the coolant from freezing and expanding in cold winter conditions, which could otherwise crack the radiator or damage the engine cylinder block or cylinder head. 2. Functions: It provides anti-corrosion protection for components of the cooling system; prevents scale formation, avoiding reduced heat dissipation efficiency of the radiator; and ensures the engine operates within the normal temperature range.

What faults will occur if the car's charcoal canister gets water inside?

If the car's charcoal canister gets water inside, the following faults may occur: 1. Heavy exhaust emissions: If you experience jerking when accelerating by pressing the throttle and notice a strong gasoline smell inside the car, pay special attention to whether the pipes in the charcoal canister system are damaged. Gasoline vapor will escape directly into the atmosphere through the damaged area, causing a strong gasoline smell inside the car. If there is a fuel leak in the pipes at this time, air instead of fuel vapor will enter the engine intake. 2. Difficulty starting the engine: In this case, pay attention to checking the charcoal canister solenoid valve that may cause the problem. If the solenoid valve remains closed, the gasoline vapor in the charcoal canister will accumulate more and more, eventually filling the entire canister, and the remaining gasoline vapor can only escape into the atmosphere, polluting the environment and wasting fuel.

Does Insurance Cover Tire Blowouts on Highways?

Car tires are considered consumable items and are generally not covered by insurance claims. However, if a tire blowout leads to a traffic accident, the insurance company will assess the situation and provide compensation accordingly. Below are specific insurance coverage details: 1. Theft of parts not covered: Insurance policies typically exclude partial theft, meaning if only certain vehicle components or accessories are stolen, robbed, or damaged, it falls under exclusions. 2. Tire blowouts not covered: Insurance does not compensate for standalone tire damage. However, if a tire blowout causes collisions, rollovers, or other accidents resulting in damage to other parts of the vehicle, the insurance company will cover those losses. 3. Waiving the right to claim not covered: In case of a collision with another vehicle where the other party is at fault, you cannot waive your right to claim compensation from them. Once you relinquish the right to seek compensation from a third party, you also forfeit your right to claim from the insurance company.

What is the maximum speed limit for a car when turning?

The maximum speed for a car when turning or making a U-turn should not exceed 30 kilometers per hour. Below is a detailed introduction about vehicle speed: 1. Overview: Vehicle speed refers to the distance a car travels per unit of time, abbreviated as speed, commonly measured in kilometers per hour or meters per second. Vehicle speed is one of the three parameters used to describe traffic flow and holds significant importance in traffic flow theory research. 2. Others: Vehicle speed can also generally refer to the speed of motor vehicles. To suit different purposes, vehicle speed is mainly categorized into spot speed, segment speed, and design speed. Spot speed is the instantaneous speed of a car passing a specific point on the road. Design speed is the speed set to determine the design indicators of various geometric elements of the road and to ensure their coordination.

How Long Can You Drive with a Blown Cylinder Head Gasket?

Cylinder head gasket failure generally means you should not continue driving. It is recommended to drive to the nearest repair shop for servicing or call for roadside assistance. The cylinder head gasket is used to seal the water jacket and cylinder liner. A blown gasket will compromise this seal, allowing coolant from the water jacket to enter the cylinder liner while combustion gases leak into the cooling system. This leads to two issues: coolant loss and overheating (since hot combustion gases entering the cooling system raise coolant temperature). Main symptoms of a blown head gasket include: 1) Coolant bubbling in the radiator with rising temperature and white exhaust smoke. 2) Engine oil emulsification (turning milky white) or oil entering combustion chambers, causing blue exhaust smoke. 3) Noticeable power loss during driving, reduced acceleration, and in severe cases, engine knocking sounds. For safety reasons, immediate gasket replacement or repair is necessary.

What Causes a Car Air Conditioner to Not Cool?

There are several reasons why a car air conditioner may not cool properly: 1. Low refrigerant level: Refrigerant loss is mainly due to leaks. If the air conditioner performs poorly and the issue recurs after refilling the refrigerant, pay attention. If the condenser is leaking, it needs to be replaced. 2. Damaged air conditioner flap: Flap motor failure is relatively rare but not unheard of. If the flap motor malfunctions, it becomes problematic. The flap motor is usually located in the lower middle part of the dashboard and serves as the master switch for the air vents. A broken switch means that even if the air conditioner can produce cold air, the air can only escape through gaps. If no air comes out from any vents when the air conditioner is turned on, be cautious. Replacing the flap motor requires dismantling the dashboard, which is a major task. 3. Dirty condenser: The purpose of cleaning the radiator and condenser is mainly for heat dissipation. In spring, willow and poplar catkins can clog the condenser, causing the engine to overheat or the air conditioner to perform poorly. Therefore, always check if the radiator is clogged with these fibers during spring. When cleaning, make sure to first use an air gun to blow away the debris before using a water gun to wash, otherwise it may have the opposite effect, leading not only to poor air conditioning performance but also increased fuel consumption.
