What Causes the Subaru Forester's Air Conditioning Not to Cool?

Subaru Forester's air conditioning not cooling is caused by a blocked expansion valve in the AC system, which prevents the refrigerant from circulating properly, thus failing to produce cooling. Here are some tips for using car air conditioning: 1. Ventilate before turning it on: After the car has been exposed to prolonged sunlight, open all four doors and the sunroof to allow air circulation for 3 minutes. This quickly lowers the interior temperature, making the AC cooling more effective. 2. Use the recirculation mode wisely: Recirculation blocks outside hot air, creating a sealed space inside the car where air rapidly circulates under the AC's effect for quick cooling. Once the interior temperature drops, it's recommended to switch to fresh air mode every 30 minutes to purify the cabin air, then switch back to recirculation after 5 minutes. 3. Turn off the AC in time: Shut off the air conditioning 5 minutes before parking to protect the engine and save fuel.

What's the reason when the car sunroof responds but fails to open?

It may be due to severe lack of lubrication in the sunroof sliding track, causing the sunroof seal to adhere to the car body. Here are some relevant introductions about sunroofs: 1. Functions of a sunroof: It can quickly lower the temperature, eliminate fogging, and rapidly exchange fresh air. Opening the sunroof while driving can quickly increase the air circulation speed inside the car, thereby improving ventilation in the cabin. 2. Precautions for sunroof use: Open the sunroof in traffic jams to prevent exhaust fumes from entering the car. During traffic congestion when all vehicles are stationary, exhaust emissions inevitably disperse in the air. Open the sunroof after sun exposure to balance interior temperature. In hot summers, when the car has been exposed to intense sunlight and the interior temperature becomes extremely high, the owner should promptly open the sunroof.

How to Solve the Brake Noise Issue in Kia Sportage?

Noise is more likely to be caused by brake pad issues. Severe wear, metal particles, or improper installation could all lead to noise. Additionally, in winter, the rubber components of the brake suspension may harden due to low temperatures, causing noise that naturally disappears once the car warms up. Below are the possible causes of brake noise: If the noise is a low-pitched thud, it might be the sound of the ABS (Anti-lock Braking System) activating. After ruling out the ABS, consider whether the cold weather is causing the brake rubber pads to deform, leading to misalignment and noise. If the noise disappears after driving for a while, this is likely the case. However, there are many potential causes for brake noise during startup, most of which are related to brake pads. Severe wear or improper installation of brake pads could cause noise. Other possibilities include issues with the brake caliper, wear on the brake pad pins, or detachment of the brake pad spring clips, all of which could also result in noise.

Is Original Car Paint Really That Important?

Original car factory paint is important. The differences between original factory paint and repainted paint are as follows: 1. The most obvious difference: Original factory paint is a high-temperature paint, baked at temperatures of at least 130 degrees Celsius, resulting in stronger adhesion of the coating; whereas the repair paint used for repainting is typically baked at around 80 degrees Celsius, with much poorer coating adhesion. 2. Original factory paint: Original factory paint consists of a primer, mid-coat, color coat, and clear coat. If the original primer is scratched off, it is completely impossible to repair this layer of original primer during repainting. This is because this primer layer is applied in the car factory's spray shop by immersing the entire car body in a paint pool and attaching it through cathodic electrodeposition, a process that cannot be replicated once the car leaves the factory. The primer applied during repainting is usually a phosphating-treated coating, which is incomparable to the original factory primer, and the adhesion process is vastly different.

Can I Add Tap Water When the Windshield Washer Fluid Runs Out?

Windshield washer fluid cannot be replaced with tap water. Windshield washer fluid serves the following functions: 1. Cleaning properties: Windshield washer fluid is formulated with various surfactants and additives. Surfactants typically have wetting, penetrating, and solubilizing functions, thereby achieving cleaning and stain removal. 2. Antifreeze properties: The presence of alcohol and ethylene glycol significantly lowers the freezing point of the liquid, providing antifreeze effects and quickly dissolving frost. 3. Anti-fog properties: A single-molecule protective layer forms on the glass surface. This protective film prevents the formation of fog droplets, ensuring the windshield remains clear and transparent with unobstructed visibility. 4. Lubrication properties: Windshield washer fluid contains a high viscosity ethylene glycol, which provides lubrication, reducing friction between the wiper and the glass to prevent scratches.
