How to Use an Automotive Air Conditioning Pressure Gauge?

An automotive air conditioning pressure gauge has two parts: the red one is the high-pressure gauge, and the blue one is the low-pressure gauge. Under normal operating conditions of the air conditioning system, the low pressure should be between 1.0—2.5 bar, and the high pressure should be between 15—18 bar. If the low pressure is higher or lower than this range, it indicates that the expansion valve is not regulating properly, or there may be an issue with the compressor's performance. The automotive air conditioning pressure gauge is used to detect the refrigeration system. If the gauge readings deviate from the normal values, it suggests that there may be a fault in the refrigeration system. Here are some common fault scenarios: 1. When the automotive air conditioning pressure gauge shows low low-pressure and low high-pressure, this may indicate insufficient refrigerant, which is a common issue. In older cars, refrigerant leaks may occur, and the problem can usually be resolved by recharging the refrigerant after inspection. 2. When the automotive air conditioning pressure gauge shows high low-pressure and high high-pressure, this may indicate a stuck-open expansion valve. Poor cooling performance, along with high readings on both the low and high-pressure gauges, suggests that the expansion valve is stuck open, allowing air to enter the refrigeration system and mix with the refrigerant, reducing cooling efficiency. Replacing the expansion valve can solve the problem. 3. When the automotive air conditioning pressure gauge shows vacuum on the low-pressure side and low high-pressure, this may indicate a stuck-closed expansion valve. If the car's air conditioning is not cooling at all, the issue is likely due to the evaporator expansion valve being stuck closed, and replacing the expansion valve is necessary. 4. When the automotive air conditioning pressure gauge shows fluctuating low-pressure readings (sometimes normal, sometimes vacuum) and fluctuating high-pressure readings (sometimes normal, sometimes low), this may indicate moisture in the refrigeration system. When moisture freezes in the pipes, it can cause vacuum conditions in the low-pressure lines. Once the ice melts, the system may return to normal. In this case, the refrigerant must be drained, the system vacuumed, and new refrigerant added. 5. When the automotive air conditioning pressure gauge shows high low-pressure and low high-pressure, this may indicate a compressor fault. If the gauge shows these readings despite sufficient refrigerant in the system, the air conditioning performance will be poor, suggesting a compressor issue. The compressor may have internal leaks, and replacing it is usually the solution.

Where is the steering wheel heating button on the Tiguan L?

The steering wheel heating button on the Tiguan L is located in a row of buttons above the air conditioning controls on the lower part of the center console. The button in the left red box is the driver's seat heating switch, and the button on the right is the front passenger seat heating switch. The Tiguan L is an SUV model under SAIC Volkswagen. Here are some details about the model: 1. Interior: The 2019 Tiguan L adopts Volkswagen's latest design language, featuring a polygonal design for the center console, breaking away from the previous rigid and conservative style. The polygonal and multi-layered design highlights the sportiness and technological feel of the new Tiguan L. 2. Powertrain: The Tiguan L is equipped with a 2.0T + 7-speed dual-clutch powertrain. The turbo fully engages at around 1500 rpm, providing ample power feedback whether starting from a standstill or overtaking on the highway. During high-speed driving, the vehicle generally maintains a speed range of 80 km/h to 120 km/h, with the engine and tire noise performance being quite ideal.

Why is the steering wheel heavy?

Steering wheel heavy reasons are: 1. Insufficient tire pressure; 2. Contaminated power steering fluid; 3. Internal failure of the power assist system; 4. Poor bearing lubrication. The working principle of a car steering wheel is to transmit torque to the rack and pinion mechanism, thereby pushing the wheels to turn left or right. Solutions for a heavy steering wheel include: 1. Replenishing hydraulic power steering fluid; 2. Replacing circuit fuses; 3. Replacing flat bearings and replenishing kingpin grease; 4. Increasing lubrication for the steering tie rod ball joint pins. Steering wheels are categorized into: single-spoke, double-spoke, three-spoke, and four-spoke steering wheels.

What is the fastest liquid to corrode car paint?

The fastest liquids to corrode car paint are strong acids and strong alkalis. The solutions for corroded car paint are: 1. Use polishing wax; 2. Sand the cracked area of the paint film to expose a complete surface and then repaint. Methods for maintaining the car paint surface include: 1. Promptly remove dust from the car body to minimize the adsorption of dust by static electricity; 2. Rinse off rain stains with clean water as soon as possible after rain to avoid damaging the paint surface; 3. Avoid washing the car under direct sunlight or high temperatures; 4. Use clean, soft cloths or sponges when washing to prevent mixing in metal shavings or sand particles, which can leave scratches; 5. Promptly remove highly corrosive stains to keep the paint surface clean and aesthetically pleasing.

Which is more fuel-efficient, coasting in neutral or coasting in gear?

Coasting in neutral is more fuel-efficient. Coasting in neutral refers to the operation method where the driver shifts the gear lever into the neutral position while the vehicle is moving, disengaging the clutch between the engine and the drive wheels, and using the vehicle's inertia to move forward. However, coasting in neutral can easily cause the vehicle to stall and is not beneficial for the car's engine. Coasting in gear refers to keeping the car in gear without pressing the clutch or accelerating, allowing the vehicle to coast forward under a certain level of engine braking. This method is only applicable to manual transmission cars; automatic transmission cars should not coast in gear. The hazards of coasting in neutral include: 1. Damage to the transmission; 2. Increased braking time and distance, affecting driving safety.

How to Install an ETC Card?

The installation method of the ETC card is as follows: 1. Purchase the ETC device, check if the device is complete, and read the installation manual; 2. Determine the installation direction of the ETC device, with the solar panel facing outward; 3. Peel off the adhesive backing of the device, fold the solar panel towards the vehicle's front windshield, and press firmly to ensure secure adhesion; 4. Install the device in the center of the upper part of the vehicle's front windshield, ensuring it does not obstruct normal driving visibility. It should be adhered in one go and not removed and reattached; 5. Insert the ETC card, activate the ETC device, and upon hearing a beep from the device and seeing the indicator light turn on, the device is activated and the installation is complete.
