How to Start a Car?

Turn to "START" to ignite the vehicle; the dashboard indicators will briefly light up and then turn off. Shift into 1st gear, turn on the left turn signal, and simultaneously observe both side mirrors and the front view to ensure safety before preparing to move. When you feel a slight vibration in the car body, a noticeable drop in RPM, and the front of the car showing signs of moving forward, it indicates that the clutch is at the semi-engaged state. Slowly release the brake, and the car will start moving smoothly. After entering the lane, promptly turn off the turn signal and accelerate to the required speed of the current lane to avoid obstructing following traffic.

Should the transmission fluid inspection hole be checked with the engine running or off?

Except for Honda transmissions, other vehicle models should check the fluid level with the engine idling. Honda transmissions are special and require checking the fluid level with the engine off. Automatic transmission fluid dipstick: Generally has 2-4 markings, usually distinguishing between cold and hot fluid levels. When checking cold, the transmission fluid level should be between the lower two marks. When checking hot, it should be between the upper two marks. Transmission: A device that changes the speed ratio and direction of motion. Used in automobiles, tractors, ships, machine tools, and various machines to alter the torque, speed, and direction of motion transmitted from the driving shaft to the driven shaft under different working conditions. Gear-driven transmissions generally consist of a housing and several gear pairs.

How much higher is the actual fuel consumption compared to NEDC?

Actual fuel consumption is 30% higher than NEDC. NEDC combined fuel consumption: New European Driving Cycle is a method used in Europe to test vehicle energy consumption, and it is also the reference basis for China's Ministry of Industry and Information Technology's comprehensive driving cycle method for testing the range of electric vehicles. NEDC combined fuel consumption test: This test does not actually place the vehicle on real roads for testing. Instead, the vehicle is fixed on a bench in a closed environment, with the tires in contact with rollers beneath the bench to simulate driving resistance at different speeds.

Reasons for Engine Overheating While Both Upper and Lower Radiator Hoses Remain Cool

Reasons for engine overheating while both upper and lower radiator hoses remain cool: The thermostat is damaged and fails to open properly, preventing the coolant in the radiator from circulating with the coolant in the engine, resulting in engine overheating. Thermostat Introduction: It is a valve that controls the flow path of the coolant. It is an automatic temperature-regulating device, usually containing a temperature-sensing component that opens or closes the flow of air, gas, or liquid through thermal expansion or contraction. Coolant Pump Introduction: Suitable for conveying water or liquids with physical or chemical properties in high-pressure operating systems, such as water supply for high-rise buildings, boiler feedwater, HVAC refrigeration cycles, hot and cold water circulation pressurization for bathrooms and equipment, and firefighting systems for conveying or pipeline pressurization. Hard alloy seals made of different materials ensure leak-free transportation of various media.

What Parts Need Maintenance for Older Used Cars?

Older used cars require replacement of engine oil, air conditioning components, spark plugs, etc. Air Conditioning Cleaning: The evaporator and fan of a car's air conditioning system remain closed and in dark conditions for extended periods. Over time, they accumulate significant dirt, mold, fungi, etc. When the AC is turned on, most of these contaminants enter the cabin. This is particularly concerning for used cars, as it can adversely affect the health of both drivers and passengers. Therefore, after purchasing a used car, the first maintenance should include a thorough cleaning of the AC ducts and evaporator box. Spark Plug Inspection and Maintenance: Spark plugs have a service life of 15,000 kilometers. When a car reaches this mileage, carbon deposits form on the spark plugs, increasing engine fuel consumption and making starting difficult. After buying a used car, it's crucial to check the gap between electrodes and whether there's any leakage between the ceramic body and metal casing to prevent spark plug issues.
