DESCRIPTION
It has been found that the inlet or outlet pipe of the receiver/drier tank may develop a pinhole at the area shown below where the pipes are held by small
steel clips. This may result in a refrigerant leak.
Galvanic corrosion occurs between the aluminum pipe and the steel clip. This condition is more likely to develop in geographic areas that use large
amounts of salt on the roads and highways.
SERVICE HINTS
^
If a refrigerant leak is suspected, inspect the pipes of the receiver/drier tank.
^
The inlet/outlet pipes are available as a service part. Refer to the parts information in this bulletin.
^
In order to prevent galvanic corrosion from recurrence, place vinyl tape (insulator tape) between the steel clip and the aluminum pipe.
REPAIR PROCEDURE

2.
Remove the following parts:
a)
