The original air conditioning lines can be visually intrusive within the engine bay. This kit relocates the A/C hoses behind the engine, creating a cleaner, less cluttered appearance while retaining the vehicle's air conditioning system.

Featuring replacement barrier-type hoses, a manifold and welded custom fittings, the kit provides a practical solution for Porsche owners looking to improve their engine bay presentation during restoration, maintenance or modification.

What Does the A/C Line Reroute Kit Do?

The kit changes the routing of the air conditioning refrigerant lines, positioning them behind the engine rather than following their original, more visible route.

This helps create a tidier engine compartment without requiring the complete removal of the air conditioning system.

Why Upgrade the Original A/C Lines?

The factory air conditioning pipework can detract from the appearance of an otherwise carefully restored or modified Porsche engine bay.

The reroute kit offers several benefits:

• Relocates visible A/C lines behind the engine
• Creates a cleaner, less cluttered engine compartment
• Improves engine bay presentation
• Uses replacement barrier-type refrigerant hoses
• Incorporates welded custom fittings to help minimise potential leak points
• Retains the original air conditioning function when correctly installed
• Ideal for Porsche restoration and custom engine bay projects

When Should It Be Fitted?

The kit is particularly suitable when restoring or detailing the engine compartment, replacing ageing air conditioning hoses or carrying out engine-out maintenance.

It can also be installed as a standalone appearance upgrade where improved A/C hose routing is desired.

Kit Contents

• New barrier-type air conditioning hoses
• A/C manifold
• O-ring seals
• Stainless steel mounting hardware
• Custom welded fittings

Installation Notes

Professional installation by a qualified automotive air conditioning technician is recommended.

The refrigerant must be safely recovered before disconnecting the original lines. Following installation, all connections, including adapter fittings and Schrader valves, should be checked for leaks using an appropriate vacuum and pressure-testing procedure before the system is recharged.

Correct hose routing and clearance from hot or moving engine components must also be verified.

Porsche 964 & 993 Air Conditioning Line Reroute Kits and Engine Bay Upgrades

The Porsche 964 and 993 are renowned for their air-cooled engines, making the appearance and condition of the engine compartment particularly important to enthusiasts and restorers.

Original air conditioning hoses can create visual clutter around the engine, especially on vehicles undergoing detailed restoration or customisation.

The Rohler A/C Line Reroute Kit provides an effective way to relocate the air conditioning pipework behind the engine, improving the overall presentation while maintaining the functionality of the original A/C system.

Design911 supplies Porsche 964 and 993 air conditioning components, replacement hoses, refrigerant lines and specialist engine bay upgrades for classic Porsche maintenance and restoration.

This rear refrigerant line from OE Match, it connects the compressor with the wheel-housing pipework within the rear air-conditioning circuit.

Fits

Porsche 993 C2 / C4 1996>>

Diagram ref no: 11

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.

Diagram: 813-30, item 16

What This Product Does

The line carries refrigerant through its section of the air conditioning circuit. Its pipework and connections form part of the sealed system needed for refrigerant circulation and cabin cooling.

Functions

• Transfers refrigerant between the wheel housing pipework and compressor.
• Provides the specified rear refrigerant connection.
• Forms part of the closed air conditioning circuit.

Technical Details

• Brand: OE Match.
• Position: Rear.
• Component identification: intake pipe, wheel housing to compressor.
• Supplied reference numbers: 99357309909 and 99357309903.
• Diagram application note: 96-, C.2/C.4.

Symptoms of Fault

• Cooling fades again following a refrigerant recharge.
• Oil staining or leak-detection dye appears around pipe connections.
• Inspection reveals corrosion, rubbing damage or deterioration at a joint.
• A substantial leak may produce an audible hiss.

These signs warrant inspection rather than confirming that this particular line needs replacement.

Why Replacement Matters

A damaged or leaking refrigerant pipe needs repair before recharging the system. Replacing a defective line addresses the source of refrigerant loss; adding refrigerant alone does not resolve damaged pipework. Inspect the adjoining seals, connections and supports during the repair.

FAQs

Could renewing the O-rings solve the leak?
It may, where the pipe remains sound and testing locates the leak at a sealed connection. Corroded or damaged pipework requires separate attention.

Will a recharge alone fix declining cooling?
Not if refrigerant is escaping through this line or another component. Locate and rectify the leak before recharging.

What should I check before choosing this part?
Confirm the vehicle's model year, C2 or C4 application and reference numbers against the existing component.

• A substantial leak may produce an audible hiss.
  
  

These signs warrant inspection rather than confirming that this particular line is faulty. Check adjoining seals and connections when locating the source.

Why Replacement Matters

Renewing a pipe with confirmed leakage or physical damage addresses the cause of refrigerant loss. Recharging without repairing the fault leaves the escape path unchanged. OE Match focuses on Porsche replacement applications; confirm the reference and connection layout against the removed component before fitting.

FAQs

Could new seals resolve the leak?
Possibly, when the connection seals are responsible and the pipe remains serviceable. Corrosion or damage to the line itself requires a different repair.

Is recharging alone sufficient?
Not when refrigerant is escaping. Locate and repair the leak before evacuating and recharging the circuit.

Who should install the line?
Use an appropriately qualified air conditioning technician for refrigerant handling, installation and system checks.
