Refrigerant is added by following these steps: 1. Close the high and low pressure manual valves on the manifold pressure gauge; 2. Connect one end of the middle hose to the refrigerant tank injection valve fitting; 3. Open the high-pressure side manual valve to the fully open position and invert the refrigerant tank; 4. Inject the specified amount of liquid refrigerant from the high-pressure side. Refrigerant is the medium substance used in various heat engines to complete energy conversion, typically utilizing reversible phase changes to increase power. During operation, a steam engine releases the thermal energy of steam, converting it into mechanical energy to generate motive power, while the refrigerant in a refrigerator is used to transfer heat from low-temperature areas to high-temperature areas to lower temperatures.

Where is the ABS pump located?

The ABS pump is located in the engine compartment near the firewall. Sometimes the ABS system in a car may malfunction, and when this happens, the ABS warning light will illuminate to alert the driver. When the anti-lock braking system fails, although the car's brake pedal can still be used, the braking performance will deteriorate, the braking distance will increase, and the handling performance during braking will also worsen. ABS is an improved technology based on conventional braking systems and can be divided into mechanical and electronic types. Modern cars are widely equipped with anti-lock braking systems. ABS not only retains the braking function of conventional systems but also prevents wheel lock-up, allowing the car to steer while braking, ensuring directional stability, and preventing skidding and deviation. It is one of the most effective braking devices in automobiles.
