SUBJECT: TRANSMISSION SHIFT CABLE CONTACTS THE A/C PIPE CAUSING A RUB THROUGH CONDITION
MODELS AFFECTED: 1987-89 CENTURYS EQUIPPED WITH 2.5L AND 2.8L ENGINES (VIN CODES R, W)
Some 1987, 1988 and 1989 Centurys with 2.5L (VIN Code R), and 2.8L (VIN Code W) engines with MD9 3-speed transmission and Air Conditioners have a potential rub through condition of the A/C pipe by the auto-transmission cable. This pipe is part of the A/C hose assembly routed along the left fender rail from evaporator to accumulator. The vibration and engine roll movement of the transaxle may cause the shift cable to rub through the A/C pipe, causing a refrigerant leak and an inoperative A/C system.
This condition may be addressed by using the following service parts and procedure to protect the A/C pipe.
