Diagram Ref No 31 (Diagram Ref No 17 Included, Diagram Ref No 25 Sold Separately)
What This Product Does:
- Supplies engine coolant from the engine/water pump area to other cooling components such as the radiator or heater circuit.
- Helps maintain proper coolant circulation and pressure, which is essential for stable engine temperature control.
- Supports cabin heating, as hot coolant routed through this hose can be directed to the heater core.
- Provides a flexible connection that absorbs engine movement, vibration, and thermal expansion without stressing rigid pipes.
- Coolant may leak from the hose itself or around the hose clamp connections, often leaving visible residue or wet patches.A leaking supply hose can cause gradual coolant loss, requiring frequent top-ups.
- Loss of coolant or restricted flow can lead to rising or fluctuating engine temperatures.
- A noticeable sweet smell around the engine bay or inside the cabin often indicates a coolant leak.
- Common signs include cracking or splitting, bulging or swelling, hardened or brittle rubber, coolant staining on the hose surface.
- If coolant flow to the heater circuit is compromised, cabin heat may be reduced.
- Modern Porsche models may display low coolant or overheating warnings when hose failure begins.
Why Replacement Matters:
- Prevents coolant leaks that cause low coolant levels and loss of system pressure.
- Helps avoid engine overheating, which can lead to severe and expensive engine damage.
- Restores proper coolant circulation, ensuring the cooling system works efficiently under all driving conditions.
- Maintains reliable cabin heating, since the heater core depends on steady coolant flow.
- Protects surrounding components, as leaking coolant can damage sensors, hoses, wiring, and nearby engine parts.

Cooling water breather pipe
OE Match cooling water breather pipe for Porsche 957 Cayenne S, GTS, Turbo and Turbo S models with the 4.8L V8 engine from 2007–10. This replacement line corresponds with OE reference 94810602604 and the earlier reference 94810602603.
Fits:
Porsche 957 Cayenne 4.8L V8 - S / GTS / TURBO 2007 - 2010
* engine codes: M48.01 / M48.51
Diagram ref no 10
What This Product Does
The breather pipe forms part of the engine water-cooling assembly. It provides the specified connection within the coolant vent circuit, supporting correct coolant circulation and helping the system release trapped air. OE Match components are produced as alternatives referenced against original-equipment applications, with suitability confirmed using the supplied vehicle and OE information.
Functions
- Connects with the engine cooling-system vent circuit
- Allows coolant and displaced air to move through the specified route
- Supports stable cooling-system operation and pressure control
- Replaces an ageing, brittle or leaking original pipe
Technical Details
- Product type: cooling water breather pipe or vent line
- Brand: OE Match
- OE reference: 94810602604
- Previous or cross-reference number: 94810602603
- Engine codes: M48.01 / M48.51
- Parts diagram reference: 10
Symptoms of Fault
- A gradual reduction in the coolant level
- Coolant odour after driving or once the engine is switched off
- Damp joints or dried coolant residue around the pipe connections
- Leaks that become visible only when the engine is hot and the system is pressurised
- Gurgling caused by air entering the cooling circuit
- A low-coolant warning or rising engine temperature
Why Replacement Matters
Repeated heat cycles can make cooling-system pipes and their connections brittle or prone to seepage. A minor leak may only appear at operating temperature but can develop into greater coolant loss. Replacing a damaged breather pipe helps restore the sealed coolant circuit and reduces the risk of overheating. Inspect adjoining seals, connections and related hoses during installation, and renew any parts showing deterioration.

FAQs
- Why can this pipe leak only when hot?
Cooling-system pressure increases at operating temperature and can expose small cracks or weakened connections. - Should the seals and nearby hoses be checked?
Yes. Inspect adjoining seals, clamps and hoses for residue, hardening or damage while access is available. - How can a small coolant leak be located?
A cooling-system pressure test can help identify seepage that is difficult to see during a visual inspection. - Is it advisable to drive with a coolant leak?
No. Continued coolant loss can cause overheating and serious engine damage.
