Information
Water hose, Return.
This OE Match engine coolant return hose is a direct-fit replacement water return hose for the original Porsche coolant hose used on 987-series Boxster and Cayman models. This hose carries coolant within the engine’s cooling circuit to help maintain stable operating temperatures under all driving conditions.
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
The OE Match coolant return hose carries engine coolant back toward the radiator or water pump, completing a section of the engine’s circulation path. By maintaining the correct flow route, it helps regulate engine temperature and prevents heat buildup that could otherwise lead to overheating.
• Position on Vehicle: Part of the engine coolant circulation system
• Replaces: OE ref no 98710650203, 98710650204
• Function: Transfers coolant within the engine cooling circuit, maintaining stable operating temperatures.
This OE Match version is ideal for routine maintenance, cooling system overhauls, or as part of preventative care on higher mileage vehicles. It fits into the existing cooling system with the factory hose clamps and integrates seamlessly with the radiator, heater core, and thermostat housing connections.
Coolant hoses are wear-items that undergo constant heat cycling and exposure to coolant chemicals. Over time, they can deteriorate, which can cause coolant leaks, reduced flow, and engine overheating. A compromised hose increases the risk of engine damage and reduced performance. Replacing aged hoses with a correctly routed OE Match unit ensures the engine cooling system retains proper pressure and flow characteristics, maintaining stable operating temperatures and protecting the engine’s long-term health.
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.
