Why does the car's AC cool while driving but heat up when parked?

Does 'outside' on the tire mean facing in or out?

The 'OUTSIDE' marking on the tire indicates the installation direction towards the outer side of the wheel hub. Below is an explanation of tire installation direction and the consequences of incorrect installation: 1. The opposite side of the tire will have an 'INSIDE' marking, corresponding to the inner side of the vehicle's wheel hub. These markings usually appear on unidirectional or asymmetric tread pattern tires. 2. If the tire's rolling direction is installed incorrectly, it can affect the vehicle's acceleration performance, increase braking distance, reduce drainage performance in rainy conditions, accelerate wear, and increase tire noise, among other issues. If the inner and outer sides of the tire are installed incorrectly, it can lead to uneven grip between the two sides of the wheels, especially on slippery roads, resulting in unsynchronized braking force, poor handling, and deviation. In extreme cases, it can affect driving safety.

What are the steps for starting an automatic transmission car?

Steps for starting an automatic transmission car: 1. Insert the key into the ignition lock, turn on the ignition switch, then observe whether all instruments are working properly, and start the engine. If any instrument is not working properly, immediately turn off the engine and check and resolve the issue before restarting the engine; 2. Press down the clutch pedal and shift the gear lever into the 1st gear position; 3. Turn on the left or right turn signal, honk the horn, and simultaneously observe the front, left, right, above, and rearview mirror of the vehicle to see if there are any obstacles to starting, paying special attention to safety; 4. Release the parking brake lever and hold the steering wheel steadily; 5. Lift the clutch pedal. The key is to quickly lift the clutch until the engine sound becomes low, then slow down the speed of lifting the clutch pedal. When the body slightly shakes, pause the clutch pedal slightly, while adding a little throttle, then slowly lift the clutch pedal while continuing to gently press the throttle with the right foot. When the left foot feels light, quickly and completely lift it off to achieve a smooth start.

What are the benefits of upgrading a car's intake system?

Under normal circumstances, the intake system does not need to be replaced. If replacement is required, the main reason is severe blockage of the intake system, commonly referred to as "carbon buildup," which leads to improper air-fuel mixture in the engine, increasing fuel consumption and accelerating engine wear. Therefore, the primary purpose of replacement is to ensure proper air-fuel mixture and maintain the engine's original power. Below are the benefits of upgrading the intake system: 1. Upgrading the intake system involves replacing the air filter with a high-efficiency, high-flow version. Installing a high-flow air filter reduces the engine's intake resistance while increasing the intake volume and volumetric efficiency per unit time during engine operation. The increased airflow is measured by the air flow meter in the fuel system. 2. The signal is sent to the fuel control unit (ECU), which then instructs the fuel injectors to spray more gasoline to match the increased airflow, allowing more air-fuel mixture (not richer) to enter the cylinders, thereby enhancing horsepower output.

What Causes Unstable Car Idling?

Below are the reasons for unstable car idling: 1. Intake manifold leakage: When unauthorized air, fuel vapor, or exhaust gases enter the intake manifold, it causes the air-fuel mixture to become too rich or too lean, leading to unstable car idling. 2. Excessive carbon buildup in the throttle body: Too much carbon buildup in the throttle body and surrounding intake passages alters the cross-sectional area of the air passage, preventing the control unit from precisely regulating the idle air intake. This also results in an overly rich or lean mixture, causing unstable car idling. 3. Faulty intake system components: The engine's intake system has many components, such as the throttle motor, idle speed control stepper motor, duty cycle solenoid valve, air flow meter, and intake pressure sensor. Any malfunction or damage to these can cause unstable car idling. 4. Fuel system issues: Problems like clogged fuel injectors, blocked fuel filters, obstructed fuel pump screens, faulty fuel pressure regulators, or clogged return fuel lines can lead to incorrect fuel injection, causing the mixture to be too rich or too lean and resulting in unstable car idling. 5. Ignition system faults: Issues such as faulty ignition modules, incorrect spark plug gaps, eroded or damaged spark plug electrodes, or excessively high resistance in high-voltage wires can reduce spark energy or cause misfires, leading to erratic and unstable car idling.

How many miles can you drive with no oil before engine seizure occurs?

Generally, driving after the engine oil has completely leaked out can lead to engine seizure. Symptoms such as knocking sounds, air leakage noises, abnormal rise in coolant temperature, reduced oil pressure, smoke from the oil filler cap, power loss, oil flooding, or oil traces on spark plugs may indicate engine seizure. Here are some preventive measures: 1. Maintain normal coolant temperature between 70~95 degrees Celsius to prevent engine overheating. Preheating measures should be taken before winter; 2. Ensure proper engine maintenance according to the manual, including correct selection of piston skirt-to-cylinder liner clearance, piston ring end gap, and side clearance. Additionally, control piston misalignment during maintenance and ensure the dimensional accuracy of cylinder liners; 3. Regularly maintain and clean the air filter to prevent dust from entering the cylinders.

What are the three filters in maintenance?

In car maintenance, the three filters that need to be replaced refer to the air filter, oil filter, and fuel filter. Below are the detailed introductions: 1. Air filter: Its function is to filter the air before it enters the cylinder, removing impurities, dust, sand, and other foreign objects. Typically, the cleaning interval for an air filter is 6,000~8,000 km. However, sometimes even if the replacement time or mileage has not been reached, the inner side of the filter element may be covered with dust or oil, requiring immediate replacement. Air filters are divided into dry and wet types, with most cars using dry air filters. 2. Oil filter: It removes various impurities from the oil, ensuring the normal operation of the lubrication system. The oil filter can be replaced along with the oil during an oil change. If the oil filter is clogged, it can be replaced, or the dirty filter element can be cleaned, dried, and reused. 3. Fuel filter: It is recommended to drain the water and sediment from the fuel filter weekly, with a general cleaning and replacement interval of 2,000-3,000 km.
