TSB: A/C COMPRESSOR REPLACEMENT - THIS BULLETIN PROVIDES THE PROCEDURE FOR REPLACING THE A/C COMPRESSOR ON SOME 2015MY K900 (KH) VEHICLES, PRODUCED FROM JOB #1 THROUGH OCTOBER 13, 2014, WHICH MAY EXPERIENCE DIMINISHED COOLING PERFORMANCE OR AN INOPERATIVE A/C SYSTEM. TECHNICIANS CAN VALIDATE THIS CONDITION BY OPERATING THE A/C SYSTEM AND BY CHECKING SYSTEM LINE PRESSURE. IF SYSTEM PRESSURES (HIGH/LOW) ARE EQUAL; CHECK FOR COMPRESSOR SEIZURE OR FOR A CRACKED COMPRESSOR CASING (COMPLETE LOSS OF REFRIGERANT). TO CORRECT THIS CONCERN, REPLACE THE A/C COMPRESSOR, INCLUDING REQUIRED ASSOCIATED PARTS PER THE TABLE ON PAGE 3, BY REFERRING TO THE APPLICABLE WORKSHOP MANUAL ON KGIS.
