What does coolant mean in a car?

Coolant in a car refers to antifreeze, and this English word is typically found on the expansion tank of the car's antifreeze system. The full name of antifreeze is antifreeze coolant, and its primary function is not to prevent freezing but to cool. Antifreeze prevents the coolant from freezing in cold winter conditions when the car is parked, which could otherwise cause the radiator to crack or damage the engine cylinder block or head. Antifreeze is a type of coolant containing special additives, mainly used in liquid-cooled engine cooling systems. It offers excellent performance in preventing freezing in winter, boiling in summer, and resisting scale and corrosion throughout the year. The effective lifespan of antifreeze is usually two years. It should be replaced when it expires or if the coolant becomes dirty. During replacement, it is essential to completely remove the old coolant, add clean water, start the engine, and let it idle for about ten minutes to circulate and clean. After stopping the engine, the clean water should then be drained.

How to Fix the EPS Light On by Yourself?

EPS light on cannot be repaired by yourself, you should immediately go to a nearby repair shop or 4S store for inspection and targeted repair. The reasons for the EPS light on are as follows: 1. Damage to the steering system sensor; 2. Failure of the steering system motor; 3. Lack of power steering fluid or leakage. The advantages of EPS are as follows: 1. High conversion efficiency: The electronic power steering system, hereinafter referred to as EPS, is a mechanical and electrical connection with a conversion efficiency of up to 90%, while hydraulic conversion efficiency is only 60%. 2. Good steering returnability: EPS has a simple structure, low internal resistance, and good returnability, providing the best steering return characteristics during steering and improving the vehicle's handling stability. 3. Low energy consumption. For hydraulic steering systems, the hydraulic power steering pump is always working when the engine is running, increasing the engine load and increasing vehicle fuel consumption by about 4%. EPS only works when steering is needed, thereby reducing engine load and saving fuel.

How long is the break-in period for the Trumpchi GS4?

The break-in period for the Trumpchi GS4 is 1,500 kilometers. Here are the precautions to take for a new car during the break-in period: 1. The engine speed should not be too high, preferably not exceeding 2,500 RPM, with an ideal speed range of 60-90 km/h. 2. During a cold start, allow the engine to warm up before driving—wait until the water temperature changes, typically 2-3 minutes; in summer, when temperatures are high, warming up for about 1 minute is sufficient. 3. Avoid sudden acceleration and hard braking, and try to maintain a steady speed. 4. The maximum speed of the vehicle during the break-in period should not exceed 100 km/h, but prolonged low-speed driving should also be avoided—pay attention to gear changes. 5. Avoid overloading the car with passengers or cargo.

How to Determine If a Car's Air Conditioning Has Too Much Refrigerant?

Signs of overcharged car air conditioning include: 1. Poor cooling performance: The current value of the compressor power supply is significantly higher than normal, the compressor engages frequently, and there may be unusual noises during high-speed operation. 2. Uneven heat dissipation on the condenser surface: Insufficient heat dissipation on the condenser surface can lead to high-pressure protection after prolonged operation. Solutions are as follows: 1. Directly release the refrigerant: The refrigerant can be discharged into the atmosphere through the high-pressure pipe valve of the air conditioning system. However, if it is R12 refrigerant, direct release is not environmentally friendly and poses certain risks, so this method is not recommended. 2. Recovery: The most standard procedure is to use a car refrigerant recovery and recharge machine. The steps involve connecting the machine's hoses to the car's air conditioning high and low-pressure pipes, setting the required amount of refrigerant to be recovered, and then starting the machine to perform the recovery.

What is the difference between a four-piston caliper and a regular caliper?

The differences between a four-piston caliper and a regular caliper are as follows: 1. Different number of pistons: Generally, family cars with disc brakes use single-piston calipers, while modified cars use four-piston caliper brakes. 2. Different braking force: The more pistons a brake caliper has, the greater, more stable, and smoother the braking force. Therefore, a four-piston caliper provides stronger braking force than a regular caliper. Here are the advantages of disc brakes: 1. Better heat dissipation: Disc brakes dissipate heat better than drum brakes, reducing the likelihood of brake fade and failure during continuous braking. 2. Faster response: Disc brake systems react quickly, allowing for high-frequency braking actions, which makes them more suitable for ABS systems. 3. More even braking force: Unlike drum brakes, disc brakes do not have a self-servo effect, resulting in more balanced braking force between the left and right wheels.

What type of engine oil does the Jetta VS5 use?

Jetta VS5 uses 5W30 engine oil. The number before the W in the oil indicates that the smaller the value, the better the fluidity of the oil at low temperatures. 0 represents the minimum working temperature of the oil at minus 35 degrees Celsius; the number after W is the index value of the oil's resistance to high temperature. The higher the value, the better the fluidity of the oil at high temperatures. Common numbers are 20, 30, 40, 50, and 60. The Jetta VS5 is the first SUV model of the Jetta brand. The front face adopts Volkswagen's X design elements and extends bidirectionally to the hood and lower grille. The design of the side lines of the body continues the Volkswagen brand design, running through the entire body.
