Some of the above vehicles, built prior to the breakpoint shown below, may exhibit a rub condition of the A/C hose to the underside of the hood.  use the following procedure to check and address this condition.  (Figure 1 shows hose disassembled for clarification only).

Procedure

1. Check the area of A/C hose, as indicated in Figure 1, to see if it is contacting the hood.  If there is no evidence of hose contact to hood, no further action is needed.
2. If the hose is contacting the hood but has not rubbed through the outer coating of hose, loosen the nut (item #4) on the accumulator (Item #5) and rotate the hose, in the direction indicated in Figure 1, to obtain clearance to the hood.
3. if the hose is rubbed through the outer coating, replace the hose assembly with one of the following service part numbers.
