This OE match breather line is a direct replacement for the original Porsche coolant vent hose fitted to Porsche 970.1 Panamera models equipped with 3.6L and 4.8L petrol engines. It forms part of the engine cooling system and helps regulate coolant circulation, pressure equalisation, and venting within the cooling circuit.
Fits:
Porsche 970.1 Panamera 3.6L >>2013
Porsche 970.1 Panamera 4.8L S / GTS / Turbo >>2013
Diagram ref no 11
The breather line vents and circulates coolant within the engine cooling system, helping maintain correct coolant pressure, eliminate trapped air, and support stable engine operating temperatures.
Function
• Connects coolant vent and expansion tank pipework
• Helps eliminate trapped air from the cooling system
• Supports coolant circulation and pressure regulation
• Maintains stable engine operating temperatures
• Reduces risk of coolant leaks and overheating
Cooling system vent hoses are constantly exposed to heat, coolant pressure, and vibration. Over time, the hose material can harden or crack, increasing the risk of coolant leaks and cooling system pressure loss. Replacing worn breather lines helps maintain reliable cooling system operation and reduces the risk of overheating or engine damage.
When to replace
• Visible coolant leaks or staining
• Cracked or brittle hose material
• Cooling system pressure loss
• Overheating or fluctuating coolant temperatures
• During preventative cooling system maintenance
• During radiator or expansion tank replacement

What This Product Does
This pipe forms part of the engine coolant breather circuit. It provides the connection used by that circuit within the cooling system.
Technical Details
- Brand: OE Match.
- Component identification: cooling water breather pipe / breather line.
- Engine identifiers recorded for this part in the supplied diagram: 4620, 4640, CWAA and CXNA.
Symptoms of Fault
- Moisture or dried coolant deposits around pipe connections.
- A sweet coolant odour following a journey.
- Coolant level falling between checks.
- Visible damage or leakage from the pipe or its fittings.
- Temperature increases or coolant warnings associated with coolant loss.
Why Replacement Matters
A damaged breather pipe or leaking connection can allow coolant to escape. Renewing a confirmed faulty component addresses the leak; inspecting adjacent connections at the same time helps identify other sources of seepage. These symptoms can also originate elsewhere in the cooling system, so diagnosis should precede replacement.
FAQs
How should a suspected leak be checked?
Inspect the pipe and connection points for dampness or deposits. A cooling-system pressure test can help locate leaks that are difficult to see.
What should be checked before selecting this pipe?
Confirm the vehicle's engine identification and compare reference 94610602622 with the component being replaced.

What This Product Does
This hose carries returning coolant through its designated section of the cooling circuit. A sound hose and correctly sealed connections help retain coolant as it circulates through the system. It is a replacement return line, rather than an expansion tank, cap or level sender.
Functions
- Provides a passage for returning coolant.
- Contains coolant within the return circuit.
- Connects the associated cooling-system components.
Technical Details
- Part reference: 97010650101.
- Component identification: coolant hose, return line.
- Supplied engine/model identifiers: 4620, 4640, CWAA and CXNA.
- Application: specified 3.6L V6 Panamera and Panamera 4 variants.
Symptoms of Fault
- Moisture or dried coolant deposits at the connections.
- A sweet odour following a journey.
- A gradually falling coolant level or recurring warning.
- Cracking near a clamp or connection.
- Swollen sections or unusually soft areas.
- Seepage that appears only when the system is hot.
- Staining beneath the engine or on the undertray.
- Gurgling or an unexpected temperature increase.
Why Replacement Matters
Renewing a deteriorated return hose addresses a potential source of coolant loss. Repeated heating and cooling, ageing and contamination can weaken hoses or their connections. Inspect neighbouring fittings, clips and sealing surfaces during the repair, since replacing the hose alone will not resolve damage elsewhere. OE Match focuses on replacement components for Porsche applications, with specification and fitment checks forming part of its development process.
FAQs
- How can a suspected hose leak be located?
A cooling-system pressure test can help reveal seepage. Examine the hose ends and nearby connections for fresh moisture or deposits. - Why might there be no puddle?
Small amounts of escaping coolant may evaporate against hot surfaces or remain trapped above the undertray. - Should the clamps also be checked?
Yes. Inspect their condition and retention, together with the adjoining fittings, before reassembly. - Do these symptoms confirm this hose has failed?
No. Nearby pipes, seals, the pump or thermostat housing can produce similar signs, so establish the leak source first.
