Genuine Porsche 95B-122-447-D Coolant Reservoir Vent Hose

The Genuine Porsche 95B-122-447-D is a factory original coolant reservoir vent hose designed for the Porsche Macan cooling system. This essential component connects the coolant expansion tank to the bleeder valve, allowing trapped air to escape from the cooling system during operation and maintaining proper coolant circulation.

Key Features:

• Genuine Porsche OEM part manufactured to exact factory specifications
• Connects coolant reservoir to bleeder valve assembly
• Essential for proper cooling system venting and air removal
• Precision-engineered fit for reliable sealing and performance
• Supersedes previous part number 95B-122-447-C
• Factory quality materials resistant to coolant and heat exposure

This vent line plays a critical role in the Porsche cooling system's automatic bleeding function. During normal operation, when coolant heats and expands, this hose allows air bubbles to travel from the high points in the cooling system to the reservoir through the bleeder valve. Proper function of this hose prevents air pockets that could lead to overheating and ensures optimal cooling performance. Genuine Porsche parts guarantee the precise fit and durability your vehicle deserves.
