Why is the car's air conditioning not cooling properly?

There are several reasons why a car's air conditioning may not be cooling properly: 1. Refrigerant leakage: Insufficient refrigerant due to leaks in the air conditioning system can cause the AC to stop cooling. Check components such as pipelines, the AC compressor, condenser, and evaporator for damage that may cause refrigerant leakage. Another method is to add fluorescent dye along with the refrigerant, then use a UV lamp to inspect the system after a week of driving - any leaking points will glow, indicating damaged components. 2. Damaged AC compressor: A faulty compressor cannot initiate the cooling process, often producing abnormal noises when damaged. Inspect the compressor and replace it if necessary. 3. Dirty condenser fins: Excessive dirt on the condenser fins can cause high pressure and temperature in the AC system, triggering the compressor to shut down as protection. Clean the condenser fins using a high-pressure water jet.

What needs to be added when the car air conditioner is not cooling?

When a car air conditioner fails to cool, it generally requires adding refrigerant (Freon). Below are the common reasons for air conditioner cooling failure: 1. Elevated air vent temperature: This is usually caused by condenser blockage. 2. Refrigerant leakage: When a car experiences refrigerant leakage, the air conditioning cooling effect will completely disappear. Here are detailed explanations of air conditioner cooling failure causes and corresponding solutions: 1. Elevated air vent temperature: Typically caused by condenser blockage. The condenser is located behind the radiator, and during driving, dust or even willow catkins can accumulate on it, leading to blockage. A blocked condenser naturally results in poor cooling performance. Solution: In such cases, the condenser should be cleaned. 2. Refrigerant leakage: When refrigerant leaks occur, the air conditioning cooling effect will completely disappear. Leakage might be caused by improper tightening during the last refrigerant refill. Solution: Check the air conditioning pipeline pressure to identify the leak location, then refill refrigerant and replace any damaged components promptly.

What is the actual fuel consumption of the Mengshi?

Dongfeng Mengshi has an average fuel consumption of 11.3L per 100 kilometers. The specific fuel consumption standard should be based on actual usage, as fuel consumption is related to multiple factors such as load, hill climbing, air conditioning usage, and low tire pressure. This model is equipped with a 6.5-ton engine, which results in relatively high fuel consumption. Common reasons for fuel consumption and solutions are as follows: Strengthen vehicle maintenance. The adjustment and maintenance of the vehicle affect engine performance and driving resistance. Statistics show that poorly maintained engines can increase fuel consumption by 10% to 20%. Owners should regularly perform routine maintenance at auto repair shops, such as checking tire pressure, wheel alignment, adjusting brake pad and drum clearance, lubricating chassis points, changing oil on schedule, and inspecting filters. Every vehicle has its optimal fuel-efficient speed, which is generally around 70-90 km/h for sedans (varies by model). High-speed driving significantly increases resistance (mainly air resistance). Proper refueling. Using higher-octane fuel is not always better. When the fuel grade is too high or too low, incomplete combustion may occur, leading to higher fuel consumption, unstable engine operation, or even damage to the engine and other critical components.

How Many Liters of Transmission Fluid Are Needed for a Highlander Transmission Fluid Change?

When changing the transmission fluid in a Highlander, manual fluid change (gravity drain) requires four to six liters; using a fluid exchange machine requires approximately nine to twelve liters. Functions of transmission fluid: Reduces friction and wear, controls clutch friction and synchronizer performance; carries loads (low-speed high torque, vibration loads), dissipates heat, reduces vibration and noise, removes contaminants from gear meshing (cleaning function); prevents corrosion, pitting, and surface metal tearing, isolates metal surfaces to prevent direct metal-to-metal contact. Hazards of not changing transmission fluid for a long time: Causes damage to the transmission's shift control mechanism; leads to abnormal wear of gears and clutch plates inside the transmission; affects the normal operation of the transmission, resulting in damage to the transmission valve body. Methods for changing transmission fluid are as follows: Loosen the drain plug at the bottom of the transmission to drain the fluid before refilling. Remove the transmission oil pan directly for draining and refilling: this method is more thorough than the previous one, removing impurities from the bottom of the oil pan. Using a circulation machine to change automatic transmission fluid: dynamic fluid exchange with an intelligent circulation machine can filter and clean sludge and impurities inside the automatic transmission.

Can You Wash Inside the Engine Hood When Cleaning the Car?

It is possible to wash inside the engine hood, but it is not recommended to do it yourself. It should be done by professionals at a 4S shop. When the engine operates at high temperatures, accumulated dirt and debris can produce unpleasant odors. Improper handling may lead to engine failure or electrical short circuits. Cleaning the engine compartment requires careful control of the water gun's flow, spray speed, and water volume. Pay attention to pipes that must not get wet and take waterproof measures for electronic devices. The engine compartment can be rinsed with water, but the angle of rinsing must be carefully considered. Always rinse from the front of the condenser, not the side, to avoid bending the aluminum fins of the condenser. Bent fins can affect engine cooling and even cause air conditioning system failures. Do not let water come into contact with the spark plugs. If water vapor enters the spark plugs, the car may fail to start. If non-original spark plugs have been replaced, there may inevitably be some gaps around the new spark plugs. It is not recommended to wash older vehicles with water. Over time, the protective piping for the wiring in the engine compartment may deteriorate. If the parking environment is poor, small animals may chew through the wiring pipes. Therefore, it is advisable to avoid water rinsing and instead use an air gun for cleaning.

Can You Get License Plates Without a Certificate of Conformity?

You cannot get license plates for a new car without a Certificate of Conformity. Here is more information about license plate registration: 1. Required documents for new car registration: ID card, Certificate of Conformity, vehicle parameter sheet, second and fourth copies of the car invoice, vehicle purchase tax receipt, car insurance policy, purchase invoice, vehicle Certificate of Conformity, ID card or organization code certificate of the invoice issuer (with copies), compulsory insurance policy, tax payment certificate, and temporary residence permit for non-locals. 2. Registration process: After preparing the documents, go to the vehicle management office to submit them, sign as the owner, have the vehicle inspected and confirmed by traffic police, choose a license plate number, receive a receipt, install and photograph the fixed license plate, and collect the vehicle license and registration certificate.
