How to Remove a Car Angle Valve?
2 Answers
First, turn off the water source by closing the main valve. Disconnect the metal hose connected to the angle valve by turning it counterclockwise. Use a specialized wrench to grip the triangular position of the angle valve and rotate it counterclockwise. Avoid using excessive force during removal, as angle valves are generally not installed very tightly.
Before removing the car angle valve, it's crucial to release the pressure first, as most angle valves are part of the air conditioning expansion valve and contain high-pressure refrigerant, making reckless handling extremely dangerous. Find a professional refrigerant recovery device and have a repair shop assist you in safely discharging the refrigerant. Once the pressure drops to zero, disconnect the pipeline connections—typically by loosening bolts or nuts with a wrench or socket tool, being careful not to apply excessive force that could damage the O-ring or gasket. After removing the valve body, check for blockages, corrosion, or leaks, as these issues are common. Remember to wear gloves and goggles to protect against residual refrigerant. Before reinstalling, perform a vacuum test to check the system's sealing, or else the cooling efficiency will be significantly compromised. It's best to carry out the entire process under professional guidance, given the intricacies of high-pressure systems.
