Information
Coolant Hose For Reservoir, Lower.
The Coolant Hose for Reservoir, Lower is a genuine Porsche OEM coolant hose designed to connect the lower section of the coolant expansion tank to the engine cooling system. This hose plays an important role in maintaining proper coolant circulation and pressure balance by routing overflow and return coolant through the closed-loop cooling circuit. Manufactured to Porsche specifications, it provides precise fitment, excellent resistance to heat and coolant exposure, and long-term durability for Porsche Panamera (971 / 976) models.

What This Product Does:
- Routes coolant between the reservoir and cooling system, allowing coolant to move in and out as temperatures change.
- Returns overflow coolant back into the closed-loop cooling circuit during normal operation.
- Helps maintain proper coolant level and system pressure balance as the engine heats up and cools down.
- Provides a flexible, heat-resistant connection that accommodates engine movement and thermal expansion.
- Coolant may drip or seep from the hose body or connections, often leaving dried residue around the reservoir.
- A leaking reservoir hose can cause gradual coolant loss, leading to frequent topping up.
- Modern Porsche models will often warn you quickly if coolant level drops.
- A coolant smell in the engine bay is a common sign of leakage.
- Signs include cracking or splitting, swelling or bulging, hardened or brittle rubber, coolant staining on the hose surface.
- Coolant loss or air entering the system can reduce cooling efficiency and cause temperature issues.
- A failing reservoir hose may lead to improper pressure control, sometimes causing coolant to escape under pressure.
Why Replacement Matters:
- Prevents coolant leaks that can lead to low coolant levels and reduced cooling efficiency.
- Maintains proper pressure control, allowing the cooling system to expand and contract safely during temperature changes.
- Helps avoid engine overheating, since coolant loss or air intrusion can disrupt circulation.
- Protects nearby components, as leaking coolant can damage hoses, wiring, sensors, and surrounding engine parts.
- Restores reliable cooling system operation, ensuring overflow coolant is properly routed within the closed-loop system.
