What This Product Does

The suction hose carries refrigerant through the low-pressure side of the air-conditioning system. It connects sections of the refrigerant circuit while accommodating movement, vibration and temperature changes during vehicle operation.

Functions

• Transfers refrigerant through the A/C suction circuit
• Helps maintain a sealed path between connected components
• Accommodates normal vibration and movement within the vehicle
• Supports correct refrigerant circulation and cabin cooling

Technical Details

• Manufacturer: Porsche
• Part number: 99657309307
• Earlier references: 99657309303 and 99657309305
• Hose specification: NW16
• Vehicle configuration: right-hand drive (RHD) only

Symptoms of Fault

• Air conditioning becomes warm again after regassing
• Cooling performance gradually declines as refrigerant escapes
• Oily deposits or leak-detection dye appear around the hose or its joints
• Cracking, abrasion or deterioration is visible on the flexible section
• A hissing noise is heard when refrigerant loss is significant
• The system cannot maintain the specified operating pressure

Why Replacement Matters

A leaking suction hose prevents the air-conditioning circuit from retaining refrigerant and pressure. Regassing alone will not provide a lasting repair if the line is damaged. Replacing the faulty hose allows the system to be evacuated, leak-tested and recharged correctly. Associated O-rings, seals and retaining hardware should also be inspected during installation and renewed where required.

FAQs

• Does the air-conditioning system need regassing after installation?
  Yes. The refrigerant circuit must be evacuated, vacuum-tested and recharged using suitable A/C servicing equipment.
• Can replacing the O-rings alone repair the leak?
  This may be possible when the pipe remains sound and leakage is limited to a joint. A cracked, abraded or deteriorated hose requires replacement.
• Is this hose suitable for left-hand-drive vehicles?
  No. The supplied application is for right-hand-drive cars only.
• Why did the system lose cooling again after a regas?
  Repeated refrigerant loss normally indicates a leak. The hose, joints and other circuit components should be inspected before recharging the system.
