2. Connect the adapter and shaft to the valve body. Make sure all connections are tight.
Failure to do this can cause refrigerant leakage.
3. Open the handle on the valve body, so the shaft can go through the body.
4. Connect the adapter to the service port of the car.
5. Push the shaft toward the service port. Slowly and carefully rotate the shaft until the tip of the shaft
engages the body of the valve core.
*NOTE: If the shaft tip does not reach the valve core, turn the locking nut counter clockwise and
back the shaft out. Then try again.
6. Once the valve core is engaged, turn the locking nut clockwise and screw it on to the shaft connection
nut.
7. This will allow one to remove the valve core without the pressure within the system disengaging the shaft
from the valve core.
*NOTE: It is not necessary to use the locking nut. Simply follow the same steps without engaging the
locking nut to the shaft connection nut.
8. Rotate the shaft counter clockwise by turning the knob of the shaft.
WARNING: MAKE SURE THE SHAFT CONNECTION NUT DOES NOT START TO TURN AS YOU
ARE TURNING THE SHAFT. THIS COULD CAUSE THE SHAFT CONNECTION NUT
TO LOOSEN AND REFRIGERANT WOULD LEAK OUT!
9. Continue rotating the shaft until you cannot turn the shaft anymore. (Do not force!!!)
10. Slowly loosen the locking nut from the shaft connection nut.
*NOTE: If the valve core is correctly removed, the shaft will automatically travel outward due to the
pressure in the system.
If it does not travel outward, either there is no pressure in the system or the valve core was not removed.
11. With the shaft pulled out all the way, CLOSE THE VALVE.
WARNING: FAILURE TO CLOSE VALVE COULD CAUSE INJURY AND WOULD RESULT IN A LOSS
OF REFRIGERANT!!!
12. Loosen and remove the shaft connection nut from the valve body.
13. Remove the damaged valve core.
