Handling of Refrigerant Lines and Fittings

1. Keep all metal tubing lines free of dents or kinks. Any line restrictions will cause the loss of system capacity.
2. Never bend a flexible hose line to a radius of less than four times the diameter of the hose.
3. Never allow a flexible hose line to come within 65 mm (2-1/2 in) of the exhaust manifold.
4. Inspect flexible hose lines regularly for leaks or brittleness.
5. Replace flexible hose lines with new lines if you find signs of deterioration or leaking.
6. Discharge the refrigeration system of all refrigerant before disconnecting any fitting in the refrigeration system.
7. Proceed very cautiously regardless of the gauge readings.
8. Open the fittings very slowly.
9. If you notice pressure when you loosen a fitting, allow the pressure to bleed off as described Discharging, Adding Oil, Evacuating, and Charging Procedures for A/C System.
10. Cap or tape any refrigerant line immediately after it is opened. This will prevent the entrance of moisture and dirt, which can cause internal compressor wear or plugged lines in the condenser, the evaporator core, the expansion valve, or the compressor inlet screens.
11. Keep the sealing surfaces in perfect condition. A burr or a piece of dirt may cause a refrigerant leak.
12. When seal washers are used, always install the seal washer without lubrication.
13. When O-rings are used, always lightly coat the new O-ring seal with mineral base 525 viscosity refrigerant oil prior to installation.

Refrigerant Leak Testing

Note. General Motors vehicles are now manufactured with fluorescent dye installed directly into the air conditioning (A/C) system.

The fluorescent dye mixes and flows with the polyalkylene glycol (PAG) oil throughout the refrigerant system.

Verifying some passive leaks may require using the J 39400-A halogen leak detector, even though the A/C system contains fluorescent dye.

The only time that adding additional fluorescent dye is required is after flushing the A/C system.

Fluorescent Leak Detector

Fluorescent dye will assist in locating any leaks in the A/C system.

1. Condensation on the evaporator core or the refrigerant lines may wash the PAG oil and fluorescent dye away from the actual leak. Condensation may also carry dye through the HVAC module drain.
2. Leaks in the A/C system will be indicated in a light green or yellow color when using the leak detection lamp. Use the leak detection lamp in the following areas: All fittings or connections that use seal washers or O-rings All of the A/C components The A/C compressor shaft seal The A/C hoses and pressure switches The HVAC module drain tube, if the evaporator core is suspected of leaking The service port sealing caps The sealing cap is the primary seal for the service ports.
3. Follow the instructions supplied with the J 42220 Universal 12V leak detection lamp.
4. To prevent false diagnosis in the future, thoroughly clean the residual dye from any area where leaks were found. Use a rag and the approved J 43872 fluorescent dye cleaner.

Fluorescent Dye Injection

1. Not all of the fluorescent dyes are compatible with PAG oil. Some types of dye decrease the oil viscosity or may chemically react with the oil.
2. R-134A leak detection dye requires time to work. Depending upon the leak rate, a leak may not become visible for between 15 minutes and 7 days.
3. To prevent false diagnosis, thoroughly clean any residual dye from the service port with a rag and the approved fluorescent dye cleaner J 43872 fluorescent dye cleaner.

Halogen Leak Detector

Ensure that the vehicle has at least 0.45 kg (1 lb) of refrigerant in the A/C refrigeration system in order to perform a leak test. Refer to Refrigerant Recovery and Recharging for recharging the A/C system.

Note. Halogen leak detectors are sensitive to the following items: Windshield washing solutions Many solvents and cleaners Some adhesives used in the vehicle

Clean and dry all surfaces in order to prevent a false warning. Liquids will damage the detector.

Note. Follow a continuous path in order to ensure that you will not miss any possible leaks. Test all areas of the system for leaks.

Follow the instructions supplied with the J 39400-A halogen leak detector.

Air Conditioning (A/C) System Performance Test (LF1 or LFW)

This test measures the operating efficiency of the A/C system under the following conditions

1. The current ambient air temperature
2. The current relative humidity
3. The high side pressure of the A/C system
4. The low side pressure of the A/C system
5. The temperature of the air being discharged into the passenger compartment

Test Description

The numbers below refer to the step numbers on the diagnostic table.

1. 1 This step determines if the A/C system has at least the minimum refrigerant charge required to operate the system without damage.
2. 2 This step measures the performance of the A/C system.
3. 3 This step is to allow for vehicle variations as well as high ambient temperatures.

Special Tools

J 34100 Smart Cart

The J 34100 Smart Cart is a complete air conditioning service center for R-134a. The Smart Cart recovers, recycles, evacuates and recharges A/C refrigerant quickly, accurately and automatically. The unit has a display screen that contains the function controls and displays prompts that will lead the technician through the recover, recycle, evacuate and recharge operations. R-134a is recovered into and charged out of an internal storage vessel. The ACR 2000 automatically replenishes this vessel from an external source tank in order to maintain a constant 5.45-6.82 kg (12-15 lbs) of A/C refrigerant.

The Smart Cart has a built in A/C refrigerant identifier that will test for contamination, prior to recovery and will notify the technician if there are foreign gases present in the A/C system. If foreign gases are present, the Smart Cart will not recover the refrigerant from the A/C system.

The Smart Cart also features automatic air purge, single pass recycling and an automatic oil drain.

Refer to the J 34100 Smart Cart Smart Cart manual for operation and setup instruction. Always recharge the A/C System with the proper amount of R-134a. Refer to Refrigerant System Specifications for the correct amount.

A/C Refrigerant System Oil Charge Replenishing

If oil was removed from the A/C system during the recovery process or due to component replacement, the oil must be replenished.
