The Porsche Genuine OE Coolant Return Hose (Part No. 94810605124) is an original equipment engine cooling system hose assembly designed and manufactured to Porsche’s exact factory specifications. It’s a dedicated coolant return line (also referred to as a water return hose or coolant pipe) used in the closed-loop cooling system of specific Porsche V8 petrol engines.

This part has superseded the former numbers 94810605121, 94810605122, and 94810605123.

Coolant hoses endure thermal cycling, pressure variations, and exposure to antifreeze, which can lead to material degradation, swelling, cracks, and leaks over time. A failing coolant return hose can result in coolant loss, overheating, and potential engine damage. Replacing worn or deteriorated hoses with Genuine Porsche OE parts ensures correct dimensions, material resilience, and leak-free performance that aligns with factory cooling system specifications

Water coolant hose - return
OE Match replacement coolant line designed to replicate the original Porsche hose in shape, length, material, and fitment. It serves as a return path for coolant within the engine cooling system, helping maintain proper circulation and temperature regulation.

Fits:
Porsche 958 Cayenne S / GTS - 2010 to 2017
Porsche 970.1 Panamera 4 / 4S / GTS - 2009 to 2013
Porsche 970.2 Panamera GTS - 2014 to 2016

Diagram ref no 15

The return hose carries coolant back toward the radiator or engine block after it has passed through the engine and other cooling components. Proper coolant flow is vital for maintaining stable engine temperatures, preventing overheating, and ensuring long-term engine longevity. A worn, cracked, or leaking hose can compromise coolant flow, lead to coolant loss, introduce air into the system, and result in overheating or engine damage.

This OE Match hose fits directly in place of the original and is supplied without additional clamps or fittings, allowing reuse of existing hardware or replacement with recommended clamps as needed. It’s ideal for coolant system maintenance, restoration work, or replacing age-affected components.

The coolant return hose completes the coolant circulation loop by transporting coolant back to the radiator/engine assembly after passage through the engine or heat exchangers. This return path helps maintain stable coolant temperatures and supports continuous heat dissipation.

Function:
• Provides a return path for coolant in the engine cooling system
•  Maintains proper coolant circulation and temperature control
•  Resists heat, pressure, and coolant breakdown
•  Design for direct fit and correct routing
•  Durable construction for long-term service

Coolant hoses deteriorate over time due to heat cycling, pressure, and exposure to coolant and engine bay contaminants. Cracks, bulges, or soft spots can develop, leading to coolant leaks, engine overheating, air ingress, and reduced cooling performance. Replacing aging hoses with an OE Match coolant return hose restores proper fluid flow, maintains engine operating temperature, and helps protect against costly engine damage.

When to replace:
•  Visible cracks, swelling, or soft spots
•  Coolant leaks or crusty coolant residue
•  Engine overheating or temperature fluctuations
•  During major coolant service (water pump, thermostat, belt service)
•  Routine preventative maintenance for older hoses
