Information
Coolant return water hose
This Porsche Genuine OE Coolant Return Water Hose is a factory-engineered cooling system hose designed for the Porsche 911 (996) Carrera 3.4L models. This molded hose forms part of the engine’s water-cooling circuit and is specifically designed to route coolant through the return section of the system.
Fits:
Porsche 996 C2 3.4L 1998 - 2001 MANUAL
Diagram ref no 3
This product supersedes Porsche's old part numbers: 99610664156, 99610664158.
The coolant return hose carries coolant from the engine return line to the main distribution/return pipe within the cooling system. This circulation allows heated coolant to travel back through the system where it can be cooled and recirculated through the engine.
By maintaining steady coolant flow through the engine’s cooling circuit, the hose helps regulate engine temperature and prevent overheating during both normal driving and high-load conditions.
Functions & Technical Role
• Coolant circulation: Transfers coolant through the return side of the cooling circuit
• Temperature management: Supports stable engine operating temperature
• Pressure tolerance: Built to withstand cooling system pressure and temperature fluctuations
• Flexible connection: Absorbs engine vibration and movement within the cooling system
• OE precision: Molded to Porsche specifications for exact routing and fitment
Fitment / Position on Car:
• Fitting position: Engine cooling system
• Location: Between the engine coolant return line and the main distribution/return pipe
• System: Engine coolant circulation / radiator cooling circuit
Coolant hoses operate under constant heat, pressure, and vibration, which can cause rubber to deteriorate over time. Aging hoses may crack or weaken, increasing the risk of coolant leaks and potential engine overheating. Replacing worn hoses with genuine Porsche OE components helps maintain the reliability and efficiency of the engine cooling system.
