Refrigerant is added to the car air conditioning system in the refrigerant storage tank. The steps for adding refrigerant to car air conditioning are: 1. Evacuate the system, close the manual valves on the pressure gauge and the high and low pressure manual valves; 2. Connect one end of the hose to the injection valve fitting of the refrigerant tank; 3. Open the refrigerant tank, loosen the nut on the pressure gauge hose to let some gas escape, then close it; 4. Open the high-pressure side manual valve and invert the tank; 5. Inject the specified amount of liquid refrigerant, then close the refrigerant injection valve and the high-pressure manual valve. Car air conditioning is used to adjust and control the temperature, humidity, air cleanliness, and air flow inside the car compartment to an optimal state, providing a comfortable riding environment for passengers and reducing travel fatigue.

How Long Does the Honda CB400 Engine Last?

Honda CB400 engines typically last for about 20 years. Engine lifespan: It's difficult to measure a car engine's lifespan simply by mileage or years.

Under normal circumstances, most engines can last about 15 years. With better maintenance, they can run for up to 20 years, covering over 600,000 kilometers. Engine maintenance tips: Always ensure the coolant level in the radiator is maintained at the normal level, and use high-quality coolant. Maintaining good driving habits can help reduce carbon buildup.

What Causes Transmission Failure in BMW Cars?

BMW transmission failure can be attributed to the following reasons: Transmission Control Program Issues: When no obvious faults are found and no error codes are detected during diagnosis, reprogramming or upgrading may be necessary.

Loose transmission grounding can also contribute to this problem.
