Installation Procedure
Important: The new O-ring seal must be coated with mineral base 525 viscosity
refrigerant oil.
- Install the new O-ring seal. Refer to
O-Ring Replacement
.
- Install the accumulator tube tube.
- Connect the accumulator
tube to the evaporator.
Notice: Use the correct fastener in the correct location. Replacement fasteners
must be the correct part number for that application. Fasteners requiring
replacement or fasteners requiring the use of thread locking compound or sealant
are identified in the service procedure. Do not use paints, lubricants, or
corrosion inhibitors on fasteners or fastener joint surfaces unless specified.
These coatings affect fastener torque and joint clamping force and may damage
the fastener. Use the correct tightening sequence and specifications when
installing fasteners in order to avoid damage to parts and systems.
