When a car loses power with the AC on, it may be due to the increased engine load caused by the air conditioning, especially during hot summer months. This can lead to higher fuel vapor levels, reduced fuel pressure in the fuel system, and insufficient fuel supply if the fuel filter is clogged. Here are some car AC maintenance tips: 1. Clean the AC vents promptly: The AC vents are often overlooked but are the dirtiest and most critical areas to clean. After prolonged use, dust accumulates in the vents due to static electricity and recirculated air, fostering bacteria and viruses. Neglecting deep cleaning can impair cooling efficiency in summer and increase fuel consumption. 2. Maintain the AC condenser regularly: The condenser is responsible for heat exchange in the AC system. If it becomes dirty or damaged, the cooling performance will significantly decline during summer use.

What to Do About Slow Tire Leaks?

Wheels with slow leaks should have their tires replaced or repaired. Below are relevant instructions for checking tires: 1. Valve core leakage: Apply some water to see if bubbles form; the solution is not to overtighten the dust cap to avoid pressing against the valve core. 2. Tire pinholes: Inflate the tire fully and scrub with a soft brush using soapy water. 3. Foreign objects puncturing the tire: These can usually be found by carefully inspecting the tire surface. For hard-to-find punctures, sprinkle water on the tire surface to locate bubbling spots—sometimes even a hissing sound can be heard. 4. Damage to the tire sidewall or inner edge: The extent of sidewall damage can often be seen directly, with severe cases showing cracks or bulges. If such damage is found, replace the tire as soon as possible to avoid blowouts.

What are the deduction points for reversing into the garage in Subject 2?

There are four deduction items for reversing into the garage: not following the specified route or sequence; the vehicle body crossing the line; failing to reverse into the garage; and stopping midway, all of which result in a 100-point deduction. Below is additional information: Subject 2: Subject 2, also known as the small road test, is part of the motor vehicle driver's license assessment and refers to the field driving skill test. For small vehicles C1 and C2, the test items include five mandatory components: reversing into the garage, parallel parking, stopping and starting on a slope, turning at a right angle, and driving through curves (commonly known as S-turns). Test Scheduling: In April 2016, the "Decision on Amending the Regulations on the Application and Use of Motor Vehicle Driver's Licenses" was officially implemented, allowing self-study for the direct test, simultaneous scheduling of Subject 2 and Subject 3, and consecutive examinations.

What Happens If Too Much Transmission Fluid Is Added?

Adding too much transmission fluid can cause issues such as oil leakage from the automatic transmission, gear shifting impact, and excessively low working oil pressure. Below are detailed explanations: Oil Leakage: If the transmission fluid level is too high, the rotating components will come into contact with the fluid during operation. Under the agitation of high-speed rotating components like planetary gear mechanisms or clutches, the fluid will expand and boil, leading to leakage from the filler hole and vent valve. Causing Gear Shifting Impact: Excessive air entering the fluid can also cause air blockage in the drain holes of the control valve body, resulting in poor drainage and leading to gear shifting impact. Causing Excessively Low Working Oil Pressure: An excessively high transmission fluid level causes the rotating components to agitate the fluid, generating bubbles. When this bubbly fluid enters the oil pump, the pump cannot establish the required oil pressure.
