Information
Engine coolant vent line
This original Porsche coolant vent / breather line forms part of the engine cooling system, helping bleed air and route coolant vapour or coolant flow correctly through the cooling circuit.
Fits:
Porsche 958 Cayenne 3.6L 2011 - 2018
Porsche 95B.1 Macan 3.0L / 3.6L 2014 - 2018
Porsche 970.2 Panamera 3.0L 2013 - 2016
Diagram ref no 12
What This Part Does / Functions
• Helps vent air from the engine cooling system
• Routes coolant or coolant vapour through the correct cooling circuit path
• Supports proper coolant circulation and system bleeding
• Helps reduce the risk of trapped air pockets in the cooling system
• Assists stable engine operating temperature
• Replaces a cracked, brittle, leaking or damaged original vent line
• Provides correct OE Porsche routing, shape and connection fitment
• Supports reliable cooling system performance.
Why Replace This Part?
Coolant vent lines are exposed to heat cycles, coolant pressure, vibration and age-related plastic or rubber deterioration. Over time, the line can become brittle, crack, split or leak. A failed coolant vent line may cause coolant loss, coolant smell, low coolant warnings, pressure loss or overheating. Replacing it with a Genuine Porsche OE engine coolant vent line helps restore correct cooling system venting and factory fitment. This is especially important on Porsche V6 applications where the coolant vent line routing is critical to proper system bleeding and coolant circulation.
Common Symptoms of a Faulty Coolant Vent Line
• Coolant smell from the engine bay
• Visible coolant leak or dried coolant residue
• Low coolant warning
• Cooling system pressure loss
• Air trapped in the cooling system
• Engine temperature fluctuations
• Brittle, cracked or broken coolant line
• Coolant seepage after previous cooling system work.
When to Replace
• This Part If the original vent line is cracked, brittle, leaking or damaged
• If coolant loss is traced to the vent line
• During cooling system overhaul or hose replacement
• When replacing related coolant pipes, hoses or thermostat components
• If the cooling system is difficult to bleed correctly
• During intake manifold or engine-top service where the line is disturbed
• When recommissioning a vehicle with unknown cooling system history
Where It Fits on the Car
This coolant vent line fits in the engine cooling system, routed around the engine coolant pipework / breather circuit. It connects into the coolant venting system and helps remove air from the cooling circuit. Correct routing and secure connections are important to prevent leaks and maintain proper cooling system operation.
