What Causes a Car's Air Conditioning to Not Cool?

There are several main reasons why a car's air conditioning may not cool properly: 1. Dirty condenser: The purpose of cleaning the radiator and condenser is mainly for heat dissipation. When cleaning, be sure to first use an air gun to blow away dirt before washing with a water gun. Otherwise, it may have the opposite effect—not only will the air conditioning not cool, but fuel consumption may also increase. 2. Substandard refrigerant and compressor oil: Excessive impurities in the refrigerant and compressor oil can also cause the car's air conditioning filter to clog, leading to poor cooling. This increases resistance and reduces the flow of refrigerant to the expansion valve, resulting in insufficient cooling capacity.

Where does the air conditioning water drain from the Nissan Sylphy?

Car air conditioning water drains from the bottom of the evaporator through a hose connected to the chassis. Here are some tips for using car air conditioning: 1. Ventilate before turning it on: After the car has been exposed to the sun for a long time, open all four doors and the sunroof to allow air to circulate for 3 minutes. This quickly lowers the interior temperature, making the air conditioning more effective when turned on. 2. Use the recirculation mode wisely: The recirculation mode blocks hot outside air, creating a sealed space inside the car, allowing the air to circulate quickly under the air conditioning for rapid cooling. Once the interior temperature has dropped, it is recommended to switch to fresh air mode every 30 minutes to purify the air inside the car, then switch back to recirculation mode after 5 minutes. 3. Turn off the air conditioning in time: Turn off the air conditioning 5 minutes before parking to protect the engine and save fuel.

Can I drive with a tire pressure of 196kpa?

Tire pressure of 196kpa is not safe for driving. According to the international GBT2978-2008 standard, the recommended tire pressure is generally 240-250kpa for standard tires, 280-390kpa for reinforced tires, with the maximum pressure not exceeding 350kpa. Hazards of low tire pressure: Increased friction with the road surface, leading to higher fuel consumption; Causes heavy steering and potential alignment issues, compromising driving safety; Increases movement of tire components, leading to abnormal heat due to excessive rolling; Reduces the effectiveness of the cord and rubber, causing delamination or cord breakage, and excessive friction with the rim, leading to tire bead damage and abnormal wear; Multiplies friction with the ground, rapidly increasing tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may result in a blowout; Increases tire body deformation, leading to sidewall cracks and flexing movements, causing excessive heat, accelerating rubber aging, cord fatigue, and breakage, while also increasing the tire's contact area and accelerating shoulder wear. Solutions for insufficient tire pressure: If no damage is visible, simply inflate to normal pressure and reset the tire pressure system; If a puncture is found, promptly drive to a tire shop for repair and reinflation; If the tire pressure warning reappears after inflation without any puncture, it may be due to a leaking rim. It is recommended to inspect and replace the rim if necessary.
