What are the reasons for Infiniti air conditioning not cooling?

Infiniti air conditioning not cooling may be caused by: 1. The air conditioning refrigerant is depleted, leading to insufficient cooling and affecting the cooling effect. In this case, you can add some air conditioning refrigerant; 2. Refrigerant leakage. The air conditioning unit inside and outside the car may work normally, but there is no cooling effect. Check the air conditioning pipelines, air conditioning pump, condenser, and evaporator components for damage that may cause refrigerant leakage, and replace any problematic parts; 3. If the car air conditioning is not cleaned, various impurities may cover the condenser, preventing it from dissipating heat normally. This can lead to excessive pressure and temperature in the air conditioning system, causing the air conditioning pump to stop cooling. Use a high-pressure water gun to clean the condenser's heat dissipation fins, then dry it with a high-pressure air gun; 4. If the air conditioning filter is too dirty, it may block the filter, preventing most of the cold air from passing through, resulting in poor cooling effect. Therefore, it is necessary to clean or replace the filter regularly.

What are the reasons for abnormal noises when driving an Audi Q5?

Audi Q5 may produce abnormal noises while driving due to the following reasons: 1. Tensioner pulley wear: The tensioner pulley's function is to tighten the engine belt, preventing the generator and power steering pump from slipping. Due to prolonged pressure and high-speed rotation, the bearings inside the tensioner pulley are prone to wear, resulting in noise and resonance. When it is confirmed that the buzzing sound and resonance are caused by the tensioner pulley, the engine mounts should also be checked, as their role is to reduce vibrations and noise generated by the engine. 2. Exhaust pipe deformation: Generally, in front-engine models, the exhaust pipe extends from the bottom of the car to the rear. Driving on rough roads or impacts to the chassis can easily cause the exhaust pipe to dent and deform. A deformed exhaust pipe increases exhaust resistance, leading to a buzzing sound and resonance. 3. Wheel hub bearing wear: The wheel hub bearings are installed in the suspension's "knuckle" and constantly bear the vehicle's weight and impacts during daily driving. The bearing balls inside are prone to wear, and the most typical symptom of bearing wear is a buzzing sound and resonance in the car.

What to Do When a Car Battery Dies?

Here are some methods to deal with a dead car battery: 1. Push-start Method: This is the most familiar and effective emergency method, but it's best used only as a last resort because it can cause some damage to the car's engine and clutch. 2. Jump-start Method: This method can be used for both manual and automatic transmission vehicles. First, open the hoods of both cars. Connect the negative terminal of the jumper cable to the negative terminal of the dead battery, and the other end to the negative terminal of the assisting car's battery. Similarly, connect the positive terminal of the jumper cable to the positive terminal of the dead battery, and the other end to the positive terminal of the assisting car's battery. Then, start the assisting car and rev the engine slightly while the stalled car attempts to start. 3. Towing-start Method: This method works on the same principle as the first one, except instead of pushing from behind, the car is pulled from the front. Of course, this method is much less strenuous than the first. First, you'll need a sturdy tow rope to securely tie the front and rear of both cars together.
