Should the A/C Be Turned On in Winter for Car Air Conditioning?

In winter, turning on the air conditioning is for heating, and there is no need to turn on the A/C. Below are the specific reasons and the principle of how the air conditioning provides warm air: Reasons not to turn on the A/C: The A/C light indicates that the air conditioning compressor is activated, which increases the engine load and fuel consumption. The warm air in a car's air conditioning system is provided by the engine coolant, so there is no need to turn on the A/C when using the heater in winter. Principle of how the air conditioning provides warm air: The warm air from the air conditioning is supplied by the engine coolant, which is the "water" in the radiator. Two hoses are connected from the engine coolant circulation loop to the heater core inside the air conditioning assembly. The warm air is delivered into the cabin by the fan, which transfers the heat from the heater core. Using the air conditioning for heating in winter neither affects the vehicle's power nor increases fuel consumption.

Do Cars Need to Change to Antifreeze Engine Oil in Winter?

Cars need to change to antifreeze engine oil in winter. Antifreeze engine oil has lower viscosity, which can protect the engine during winter. Engine oil that has been used for a long time, turned black, or has reduced adhesion should be replaced to ensure smooth engine startup. Below are the methods and precautions for changing engine oil: Methods for Changing Engine Oil: Loosen the nut at the bottom of the transmission oil pan to allow the old transmission oil to flow out naturally by gravity; connect the transmission and the circulation machine through pipeline interfaces, and the pressure-type transmission oil will push out the old transmission oil; remove the oil pan for oil change. Precautions for Changing Engine Oil: When changing the engine oil, it is best to replace the oil filter as well, otherwise accumulated impurities can easily cause blockages; the oil pan bolt should be replaced each time the oil is changed; try to choose multi-grade oil, as it is economical, has a long service life, and provides good protection for the engine.

Can Antifreeze Still Be Used After 10 Years?

Antifreeze cannot be used after 10 years. The shelf life of antifreeze (unopened) is 2-3 years from the date of manufacture. Antifreeze Replacement Cycle: Vehicle antifreeze generally needs to be replaced every 2 years or 40,000 kilometers. This is just a reference cycle. For commercial vehicles with higher mileage, the replacement cycle is shorter. Since driving conditions vary for each vehicle, the replacement should be based on actual usage. Check the antifreeze's condition—if it is insufficient, replenish it promptly. If suspended particles, sediment, or signs of deterioration or discoloration are found, replace the antifreeze and clean the system immediately. How to Choose Antifreeze: The basic indicators of antifreeze are its freezing point and boiling point. On the market, antifreeze is available with freezing points of -15°C, -25°C, -30°C, -40°C, etc. Generally, it is advisable to choose one with a freezing point at least 10°C lower than the lowest temperature in your region.

How does the ESP work?

ESP works by: sensor signals determining the driving state, and through calculations, the control unit performs optimal control. When rotation, understeer, or oversteer occurs, it individually controls each wheel to improve vehicle stability, and controls indicator and warning lights based on the vehicle's condition. ESP (Electronic Stability Program) is an active safety system, a non-independent system built on top of other traction control systems. Its control steps are: 1. The ECU determines the driver's intention and analyzes the vehicle's movement state; 2. When there is a significant deviation between the driver's intention and the vehicle's movement, the hydraulic pressure control device adjusts the braking force of each wheel separately, and adjusts the engine output through the communication circuit connected to the engine to prevent accidents.

How to Read the Fuel Gauge on a Vios?

Method to read the fuel gauge on a Vios: 1. The Vios uses an analog fuel gauge; 2. When the needle points to F, it indicates a full tank; 3. The closer the needle is to E, the lower the fuel level, meaning less fuel remains. The instrument cluster is located behind the steering wheel. The leftmost gauge is the engine tachometer, the larger middle gauge is the vehicle speedometer, and the rightmost gauge is the fuel gauge. The current gear position information can be viewed on the LCD screen. The Vios is an entry-level family car under Toyota, with body dimensions of 4435mm in length, 1700mm in width, and 1490mm in height, a wheelbase of 2550mm. It is equipped with a 1.5L 110 horsepower L4 engine and a 5-speed manual transmission.
