DIAGNOSIS AND TESTING - REFRIGERANT SYSTEM LEAKS
WARNING: REVIEW THE WARNINGS AND CAUTIONS IN THE FRONT OF THIS SECTION BEFORE PER-
FORMING THE FOLLOWING OPERATION. (Refer to 24 - HEATING & AIR CONDITIONING/PLUMBING - WARN-
ING).
If the air conditioning system is not cooling properly, determine if the refrigerant system is fully-charged. (Refer to 24
- HEATING & AIR CONDITIONING - DIAGNOSIS AND TESTING).
An electronic leak detector designed for R-134a refrigerant is recommended for locating and confirming refrigerant
system leaks. Refer to the operating instructions supplied by the equipment manufacturer for proper care and use
of this equipment.
An oily residue on or near refrigerant system lines, connector fittings, components, or component seals can indicate
the general location of a possible refrigerant leak. However, the exact leak location should be confirmed with an
electronic leak detector prior to component repair or replacement.
To detect a leak in the refrigerant system, perform one of the following procedures:
SYSTEM EMPTY
1. Evacuate the refrigerant system. (Refer to 24 - HEATING & AIR CONDITIONING/PLUMBING - STANDARD
PROCEDURE).
2. Connect and dispense 0.283 kilograms (0.625 pounds or 10 ounces) of R-134a refrigerant into the evacuated
refrigerant system. (Refer to 24 - HEATING & AIR CONDITIONING/PLUMBING - STANDARD PROCEDURE).
3. Position the vehicle in a wind-free work area. This will aid in detecting small leaks.
4. With the engine not running, use an electronic R-134a leak detector and search for leaks. Because R-134a
refrigerant is heavier than air, the leak detector probe should be moved slowly along the bottom side of all refrig-
erant lines, connector fittings and components.
5. To inspect the evaporator coil for leaks, insert the electronic leak detector probe into the center instrument panel
outlet. Set the blower motor switch to the lowest speed position, the A/C button in the On position, and select the
Recirculation Mode.
SYSTEM LOW
1. Position the vehicle in a wind-free work area. This will aid in detecting small leaks.
2. Bring the refrigerant system up to operating temperature and pressure. This is done by allowing the engine to
run with the air conditioning system turned on for five minutes.
3. With the engine not running, use an electronic R-134a leak detector and search for leaks. Because R-134a
refrigerant is heavier than air, the leak detector probe should be moved slowly along the bottom side of all refrig-
erant lines, connector fittings and components.
4. To inspect the evaporator coil for leaks, insert the electronic leak detector probe into the center instrument panel
outlet. Set the blower motor switch to the lowest speed position, the A/C button in the On position, and select the
Recirculation Mode.
STANDARD PROCEDURE
REFRIGERANT SYSTEM SERVICE EQUIPMENT
WARNING: EYE PROTECTION MUST BE WORN WHEN SERVICING AN AIR CONDITIONING REFRIGERANT
SYSTEM. TURN OFF (ROTATE CLOCKWISE) ALL VALVES ON THE EQUIPMENT BEING USED, BEFORE
CONNECTING TO OR DISCONNECTING FROM THE REFRIGERANT SYSTEM. FAILURE TO OBSERVE THESE
WARNINGS MAY RESULT IN PERSONAL INJURY.
WARNING: REVIEW THE WARNINGS AND CAUTIONS IN THE FRONT OF THIS SECTION BEFORE PER-
FORMING THE FOLLOWING OPERATION. (Refer to 24 - HEATING & AIR CONDITIONING/PLUMBING - WARN-
ING).
When servicing the air conditioning system, a R-134a refrigerant recovery/recycling/charging station that meets SAE
Standard J2210 must be used. Contact an automotive service equipment supplier for refrigerant recovery/recycling/
