The air conditioning system of an automobile gives the vehicle cold, conditioned controlled air for the sake of comfortable driving. What powers the system is refrigerant that will need regular maintenance for the air conditioning system to run efficiently. The two refrigerant types used in automobiles are Dichlorodifluoromethane and 1, 1, 1, 2-Tetrafluoroethane, known as R-12 and R-134a. Freon is no longer used in newer automobiles. R-134a, is now its replacement for air conditioning servicing.
Pop open the hood of the automobile by pulling the release latch by the driver side door. Ensure that the automobile is not running.
Determine the type of air conditioner that you have mounted to the automobile's engine. Afterward, follow the lines that are protruding from it. A 16-millimeter fitting is on one line while a smaller 13-millimeter fitting is on the other line. Take off the protective cap from the smaller fitting, which will be the low side R-134a service fitting.
Ensure that you put on a pair of safety goggles to protect your eyes. Puncture the can's seal by closing the valve on the servicing hose. Allow air to escape from the service hose by quickly opening and closing the valve.
Take the end of the service hose and attach it to the R-134a service fitting. Start the automobile's ignition. Afterward, put the air conditioning up to its highest cooling settings.
Open up the servicing hose's valve. The refrigerant will get sucked in by the air conditioning system. The air conditioning vents should now start emanating colder air.
Observe the service hose's gauge. If it reads between 25-40 psig, close the valve. Remove the service hose from the R-134a fitting. Put the protective cap back on. Turn off the automobile and close the hood.
