SERVICE INFORMATION

If there is an incident of "no cooling" and the A/C system is found to be low or out of refrigerant, the high and/or low side charge port Schrader valve core(s) may be a source of the leak. Perform the following procedure to determine if the Schrader valve is the cause of the leak.

SERVICE PROCEDURE

1. Verify the vehicle is included in one of the VIN ranges listed above.

2. Perform a refrigerant leak test on the A/C system to determine if the system is leaking. If the leak test determines that the refrigerant leak is at one or both of the charge valve ports, carry out the following procedure:

A. Check that the valve core is tight in the charge port valve body. Torque should be 2.6 in. lb. (3 Kg-cm). If the valve core is not torqued to specification, torque to specification and retest for leaks. If the valve core is torqued to specification, proceed to Step 213.

B. Recover the refrigerant from the A/C system.

C. Remove the suspected valve core(s).

D. Install new valve core(s) using P/N J2138-89910.

E. Reinstall dust cover/seal cap.

F. Evacuate and recharge the A/C system to specification.

G. Retest for leaks.
