Under compressor conditions of 1500~2000rpm, the normal high pressure (discharge pressure) is around 1.5~2.0mpa, and the low pressure (suction pressure) is around 0.15~0.35mpa. The specific values depend on different vehicle air conditioning system configurations and ambient temperatures. Here are relevant introductions: 1. Car air conditioning refrigerant: The so-called car air conditioning refrigerant is commonly referred to as Freon, also known as "refrigerant" or "coolant" in the market, which is divided into environmentally friendly types (R134a) and non-environmentally friendly types (mainly F12). 2. Refrigerant pressure gauge: The refrigerant pressure gauge, also called a refrigerant meter or Freon gauge, is used to measure the current pressure of the refrigeration system. It is mainly used to detect the pressure values of the refrigerant at different stages of the system, helping operators understand the operating status of the equipment. Currently, China requires the accuracy of refrigerant pressure gauges to reach grade 2.5.

Is a Car Not Considered Flood-Damaged If the Interior Doesn't Get Wet?

If the interior of a car doesn't get wet, it is not considered a flood-damaged vehicle. Below are methods to identify flood-damaged cars and ways to handle water entering the cabin: Methods to Identify Flood-Damaged Cars: Smell the interior: Check for any musty odors. Flood-damaged cars often have musty smells in hidden areas such as under the floor mats, trunk liners, and beneath the seats, which are difficult to clean and usually leave evidence. If you detect a musty smell, be cautious. If the interior smells unusually fragrant, it might be an attempt to mask the musty odor. Inspect hidden areas: Check for rust or signs of replacement on screws in concealed parts of the car. Pull back the seats to inspect the tracks for rust or sand. Extend the seatbelt fully to check for water stains or dirt at the end. Methods to Handle Water in the Cabin: If water enters the cabin, the repair process mainly involves removing the accumulated water. There are several rubber plugs at the bottom of the vehicle's chassis—opening these can drain the water from the cabin. However, since interior materials like floor coverings are highly absorbent, they should be removed and placed in a well-ventilated area to facilitate evaporation. Water in the cabin often contains dirt and mud, so on sunny days, removable interior items like floor mats and seat covers should be taken out to dry and clean. For less dirty carpets, a vacuum cleaner can be used directly.

What does the TC light mean on a Buick?

Buick displaying TC indicates a malfunction in the Traction Control System. In this case, you should visit a Buick 4S dealership to have a technician read the fault codes, identify the cause and location of the issue, and proceed with immediate repairs. Below is information about the Traction Control System: 1. The Traction Control System relies on electronic sensors to detect when the driven wheels' speed is lower than the driving wheels (a sign of wheel slip). It then sends a signal to adjust ignition timing, reduce throttle opening, decrease acceleration, downshift, or apply braking to the wheels, preventing further slipping. 2. The Traction Control System enhances driving stability, improves acceleration, and increases climbing capability.

What causes the abnormal noise in Volkswagen Tiguan's D gear at idle speed?

Volkswagen Tiguan's abnormal noise in D gear at idle speed may originate from the transmission area. Possible causes include: 1. Insufficient transmission oil or deteriorated oil quality. 2. Worn, loose, or damaged transmission bearings. 3. Bent transmission shaft. 4. Abnormal gear meshing, with excessive or insufficient meshing clearance. 5. Metal peeling on gear tooth surfaces, broken gear teeth, or misalignment during repair and assembly. 6. Loose connection between the gearshift lever and the transmission fork groove. Diagnostic approach: When abnormal engine noise occurs, it inevitably generates certain vibrations. Therefore, the characteristics and location of the vibrations should be used to assist in diagnosing the cause of the abnormal noise.
