Information
Water hose, Return.
The Genuine Porsche 98710650204 coolant hose (replacing 98710650203) is an OEM-spec cooling line for 987 Boxster and Cayman models, designed to transfer coolant between key components for stable engine temperatures and long-term reliability. Made from high-grade, multi-layer reinforced rubber and shaped to factory routing, it delivers superior heat and pressure resistance with perfect, leak-free fitment.
Fits:
Porsche 987.1 Boxster 2.7L / 3.2L / 3.4L 2005 - 2008
Porsche 987C.1 Cayman 2.7L / 3.4L 2006 - 2008
Diagram ref no 1
• Position on Vehicle: Part of the engine coolant circulation system
• Replaces: 98710650203
• Function: Transfers coolant within the engine cooling circuit, maintaining stable operating temperatures.
Using a genuine OEM coolant hose ensures the cooling system maintains proper flow, prevents overheating, and supports the long service life expected of a Porsche flat-six engine. This part is essential for maintaining factory performance, especially on aging or high-mileage 987 models where rubber hoses naturally harden or deteriorate over time.
Coolant hoses operate under high temperature and pressure. Over time, age, heat cycles and coolant exposure cause internal deterioration or external cracking. A compromised hose can lead to:
• Coolant leaks Engine overheating
• Sudden loss of coolant pressure
• Potential engine damage.
Replacing worn hoses with a Genuine Porsche unit ensures proper sealing, correct routing and dependable cooling system function.
Typical reasons to replace:
• Visible cracking, bulging or soft spots
• Coolant smell or residue around hose ends
• Overheating issues or fluctuating temperatures
• During cooling system service (pumps, thermostats, radiators)
• Preventative maintenance on older 987 models.
