What Are the Causes of High Pressure in Car Air Conditioning?

Here are the reasons for high pressure in car air conditioning: 1. Insufficient cooling water flow or excessively high water temperature. 2. Excessive buildup of dirt in the condenser copper tubes, leading to poor heat exchange efficiency. 3. Excessive refrigerant. 4. Air presence in the air conditioning system. 5. Expansion valve failure. 6. Cooling fan malfunction. 7. Engine overheating. Below is additional information on how to check car air conditioning pressure: 1. The red gauge indicates high pressure, while the blue gauge indicates low pressure. 2. The black circle inside the air conditioning pressure gauge typically shows normal refrigeration pressure between 0.4 to 0.5 MPa, and normal heating pressure between 1 to 1.5 MPa. 3. The outer ring unit of the air conditioning pressure gauge is MPa, representing the refrigerant's evaporation temperature, with the outermost scale displaying the refrigerant's pressure value.

What does the R gear mean?

R gear is the reverse gear. When using this gear, the vehicle must come to a complete stop before engaging it. It is strictly prohibited to shift from a forward gear into reverse while the vehicle is in motion to prevent gear damage. How to use the R gear: For models equipped with an automatic transmission, first press the brake pedal and then press the safety button on the gear lever or push down the gear selector to engage or disengage the R gear. The R gear can be engaged from P (Park) or N (Neutral), but switching between D (Drive) and R requires passing through N gear. In other words, to shift from D to R, you must first shift to N, which helps reduce the impact of reverse oil flow in the transmission during gear changes. For models with a manual transmission, first bring the vehicle to a complete stop, then press the clutch and brake, shift into R gear, and finally perform a semi-clutch operation with slight throttle input. The function of the R gear: Its primary function is to enable the vehicle to move in the opposite direction, allowing it to reverse. In manual transmission vehicles, it also serves as a hill-hold function. When parking on a downhill slope, the drive shaft can be mechanically locked by engaging the reverse gear. However, this should not be overly relied upon, as the vehicle's braking system is the primary method for stopping. Using reverse gear for braking carries certain risks.

Is the Dash Cam Automatically Recording?

Dash cams are designed to record automatically. Below are the instructions for using a dash cam: 1. Press and hold the power button to turn the device on or off. 2. When connected to a charger, the DVR will automatically turn on, and it will automatically shut down with a 5-second delay after disconnecting the charger. 3. In recording mode, the DVR will automatically start recording upon turning on, with the recording indicator symbol flashing. To stop recording, press the OK button. 4. Photo mode. After turning on the device, press the mode button to select photo mode, then press the OK button to take a photo. 5. Preview mode. After turning on the device, press the mode button to select preview mode, use the up/down buttons to choose a video file, press the OK button to play or pause, and press the mode button to exit.

How Often Should a Sedan Have Its Oil Changed?

Sedans should have their oil changed every 6 months, requiring at least two oil changes per year. Below are different oil change intervals: 1. Time: Conventional oil - 3-4 months; Full synthetic oil - 6-9 months. 2. Mileage: Conventional oil - 5,000 km (4,000 km for daily traffic congestion, dusty, extremely hot, or cold regions); Semi-synthetic oil - 7,500 km (6,000 km for daily traffic congestion, dusty, extremely hot, or cold regions); Full synthetic oil - 10,000 km (8,000 km for daily traffic congestion, dusty, extremely hot, or cold regions). 3. Long-distance vehicles (no traffic congestion, constant speed driving): Conventional oil - 5,000 km; Semi-synthetic - 7,500-10,000 km; Full synthetic - 10,000-15,000 km.

What are the hazards of driving with the handbrake on?

Driving with the handbrake on can wear out the handbrake pads, and excessive wear may lead to brake failure. The following are the impacts of driving without releasing the handbrake: 1. The most direct effect of driving with the handbrake on is accelerated wear of the brake discs and the hardening of the brake pads due to overheating, as well as the elongation of the handbrake cable, resulting in reduced braking performance. The burnt smell noticed by the driver comes from this, and in severe cases, smoke may even appear from the rear of the vehicle. 2. Driving for a long time with the handbrake on can cause the brake calipers to seize, brake fluid leakage, and excessively high brake fluid temperature, leading to a complete loss of braking function.

How to Use Car Glass Anti-Fog Spray?

Here are the steps to use car glass anti-fog spray: 1. Pour a small amount of anti-fog spray onto a clean cotton cloth or tissue. 2. Wipe the glass surface back and forth and let it dry. 3. Reapply if necessary to maintain a fog-free state. Here are the precautions for using glass anti-fog spray: 1. Flammable. Use only in well-ventilated areas. 2. Do not ingest. If accidentally swallowed, induce vomiting and seek medical attention immediately. 3. Do not inhale the spray mist, as it may cause drowsiness or dizziness. 4. Do not puncture, crush, or burn the can, even when empty. 5. Keep out of reach of children. Store away from children. 6. Ensure a sufficient thickness of the anti-fog film to guarantee excellent anti-fog performance.
