Volkswagen Sagitar air conditioner sometimes cools and sometimes does not may be due to a clogged air filter. Reasons for car air conditioner failure: Lack of Freon: The reason for this situation is usually a leak in the air conditioning system pipes. The filter is too dirty: You can try to find the bypass valve on the filter element base. When the pressure difference on both sides of the valve reaches a certain value, it can open. Generally, the oil flows into the main pipe through this pipe. Use a car-specific lubricant to lubricate the relevant parts, and the situation will improve. The function of the car air conditioner: It works according to the set temperature to adjust and control the temperature, humidity, air cleanliness, and air flow in the car compartment to an optimal state, providing a comfortable riding environment for passengers, reducing travel fatigue, creating good working conditions for the driver, and ensuring safe driving.

The Volkswagen Sagitar's air conditioning sometimes cools and sometimes doesn't, which is mostly due to issues with the refrigeration system. Last time I encountered a similar situation, I found it might be caused by refrigerant leakage or insufficient levels, leading to unstable pressure and intermittent compressor operation. A faulty compressor clutch can also cause repeated cooling interruptions, especially common in older vehicles. A malfunctioning temperature control sensor may send incorrect signals, causing the AC to misjudge the cabin temperature and cycle on and off. Additionally, frozen or clogged evaporators can block airflow and affect cooling. These problems make the car's AC alternate between cold and hot during summer drives, which is quite annoying. It's recommended to first check the refrigerant level, and if that doesn't help, visit a repair shop to test the electrical circuits to prevent sudden loss of cooling while driving. Safety first—never delay necessary repairs.

What transmission is used in the Lexus ES?

Lexus ES uses two types of transmissions in total, one is a CVT transmission, and the other is an 8AT transmission. The introduction of these two transmissions is as follows: 1. The internal structure of the CVT transmission is very simple, consisting of two cone wheels and a steel belt inside this transmission. The steel belt of the CVT transmission can move on the cone wheels, allowing the transmission to change speed and torque. 2. The AT transmission is connected to the engine through a torque converter, which is filled with transmission fluid, so the shifting smoothness of the AT transmission is also relatively good.

What does EGR mean in cars?

EGR in cars refers to the Exhaust Gas Recirculation system. Here is a related introduction to automotive EGR: 1. The EGR system in vehicles is designed to reduce NOX emissions from automobile exhaust, ultimately decreasing atmospheric pollution. 2. There are two conditions for NOX generation: high temperature and oxygen abundance. Since exhaust gases contain large amounts of CO2, which cannot burn but can absorb significant heat. 3. Therefore, introducing exhaust gases into combustion can lower the combustion temperature of the air-fuel mixture in the cylinders, improving the high-temperature oxygen-rich condition, thereby effectively suppressing NOX emissions.

What tires are used on the Trumpchi GS4?

Trumpchi GS4 is equipped with Michelin PRImACY-3ST tires in the specification 215/55-R18. Below is more information about this tire model: 1. The Primacy-3ST's tread pattern features variable pitch block design. Four longitudinal grooves divide the tread pattern into five sections, with the middle three sections having identical patterns that all utilize variable pitch design to disrupt noise during tire operation. 2. The outstanding handling performance of Primacy-3ST comes from Michelin's "FLEXMAX" technology. The combination of flexible tread rubber and chamfered block design allows the tire to better conform to the road surface, providing stronger grip; while the wide chamfer design maximizes the tire's contact patch area, further enhancing traction.
