What This Product Does
The line carries refrigerant through its section of the A/C circuit. Sound pipework and sealed connections are necessary to retain the refrigerant charge used for cabin cooling.
Functions
- Transfers refrigerant between the compressor and wheel-housing connection.
- Forms part of the enclosed rear refrigerant circuit.
Technical Details
- Brand: OE Match.
- Position: Rear.
- Supplied part references: 99357309709 and 99357309703.
- Internal diagram identification: 99357309703, compressor-to-wheel-housing refrigerant line.
Symptoms of Fault
- Cooling fades again following a refrigerant recharge.
- Oil traces or leak-detection dye appear around connections.
- Pipework shows corrosion, cracks or contact damage.
- A substantial leak may produce an audible hiss.
These signs warrant inspection; reduced cooling does not by itself establish that this line is faulty.
Why Replacement Matters
A damaged line must be repaired or renewed to address the source of refrigerant loss. Recharging without resolving a confirmed leak leaves the underlying fault in place. During replacement, inspect adjoining seals, mounting points and clips for deterioration or rubbing.
FAQs
Could new O-rings resolve the leak?
They may be sufficient where a connection seal is responsible and the pipe remains serviceable. Corrosion or damage to the line requires a different repair.
Is another recharge enough?
Repeated refrigerant loss calls for leak diagnosis before further charging.
Who should carry out the work?
Use an appropriately qualified air-conditioning technician for refrigerant-system repairs.
Check fitment for your specific vehicle (model, year, engine) before ordering.
