Here are the reasons why air conditioning systems may produce odors: 1. Prolonged use of the air conditioner can lead to the accumulation of dust on the indoor filter and inside the copper coils. When a certain amount of dust builds up, it can generate an odor, which is then dispersed into the air when the air conditioner is turned on. 2. After cooling or heating, the indoor unit of the air conditioner often retains moisture. If the air conditioner is turned off immediately without a drying or anti-mold function, the moisture remains inside, leading to the growth of mold over time, which produces a musty smell. Here are some methods to eliminate odors: 1. If the air conditioner has been used for a short period and only has dust on the panel and vents, simply wipe it down and remove the filter for rinsing with clean water. 2. If the air conditioner has been used for a long time and the user cannot perform a simple cleaning, it is necessary to contact after-sales service for a thorough cleaning to ensure the air conditioner emits healthier and fresher air.

What Causes Brake Noise at Low Speeds?

There are several main reasons why brakes may produce abnormal noises during low-speed driving: 1. Brake pad break-in: New cars or newly replaced brake pads require a break-in period for optimal performance. 2. Foreign particles: Sometimes small particles like sand can get between the brake pads and rotors, causing noise due to friction. This usually doesn't require repair - driving for a while can help dislodge these particles. 3. Brake system malfunction: If the noise is accompanied by brake failure, immediate inspection and repair are needed. Missing or damaged brake rotor mounting screws, or insufficient lubrication can also cause brake noise.

How Long Does It Take for the Engine Coolant Temperature to Rise After Starting the Car?

Generally, it takes about 15 minutes for the coolant temperature to rise. Here is some information about car coolant temperature: 1. The temperature of the engine coolant should not be too low; it is generally recommended to keep it above 90 degrees Celsius. 2. You should not drive immediately after starting the car because the idle speed is quite high when the engine is cold, and the lubrication is not yet optimal. Driving at this stage will inevitably increase the engine load and accelerate wear. 3. The correct approach is to let the vehicle warm up naturally at idle until the coolant temperature begins to rise, and then wait for the idle speed to return to normal levels before driving.
