What This Product Does
The breather pipe provides a venting route within the coolant circuit. Its connections need to remain intact and leak-free for the cooling system to function correctly.
Technical Details
- Brand: OE Match.
- Engine capacity: 4.5L.
- Supplied cooling diagram applications: M48.00 / M48.50, Porsche 955 Cayenne 2003–06.
Symptoms of Fault
Possible signs include damp pipe connections, dried coolant deposits, a sweet coolant smell or a gradually falling coolant level. Leakage may become apparent only when the engine is hot. These symptoms can also originate elsewhere in the cooling circuit, so confirm the source before replacing parts.
Why Replacement Matters
A damaged pipe or leaking connection can allow coolant loss. Renewing a confirmed faulty component addresses the affected section; inspect adjoining connections and supporting seals during the repair.
FAQs
How can a suspected leak be checked?
A cooling-system pressure test and inspection for fresh moisture can help locate seepage, including leaks in less accessible areas.
What should be checked before ordering?
Match reference 94810601603 to the existing component and confirm the vehicle variant, engine and production year.

This OE Match cooling water breather pipe is a direct replacement for the original Porsche coolant vent line fitted to selected Porsche 970 Panamera and 958 Cayenne V8 models. Installed within the engine cooling circuit, the breather pipe connects key coolant passages and allows trapped air and coolant vapour to be vented correctly through the system. Proper coolant venting is essential on high-performance Porsche V8 engines to prevent air pockets, maintain stable coolant flow, and support efficient engine temperature regulation.
Fits:
Porsche 970 Panamera 4.8L V8 2010-2016 S / GTS / TURBO
* engine codes: M48.20 / M48.40 / MCX.PA / MCX.RA / MCX.P / MCX.R / MCW.BA / MCW.CA / MCW.B / MCW.C
Porsche 958 Cayenne 4.8L V8 2011-2018 S / GTS / TURBO / TURBO S
* engine codes: M48.02 / M48.52 / MCF.TB / MCY.XA / MCF.T / MCY.X
Diagram ref no 11
The cooling water breather pipe vents and circulates coolant within the engine cooling system, helping eliminate trapped air and maintain correct coolant pressure and flow throughout the engine.
Function
• Vents trapped air from the cooling system
• Supports proper coolant circulation and pressure regulation
• Helps maintain stable engine operating temperature
• Reduces risk of air pockets within cooling system
• Protects against coolant leaks and overheating
Cooling system hoses and breather pipes are constantly exposed to heat, coolant pressure, and vibration. Over time, the material can harden, crack, or become porous, increasing the risk of coolant leaks and air entering the cooling system. Replacing ageing breather pipes helps maintain reliable cooling system operation and prevents potential engine overheating issues.
When to replace
• Visible coolant leaks or staining
• Cracked or brittle coolant hose material
• Cooling system pressure loss
• Overheating or fluctuating coolant temperatures
• During preventative cooling system maintenance
• During engine or coolant hose servicing
