Information
Water / Coolant pipe O-ring 22 x 3 mm
This OE Match O-Ring (22 x 3 mm) is a high-quality replacement sealing component designed to meet original Porsche specifications for fit, durability, and performance. This O-ring is used within the engine cooling system, sealing coolant pipe connections to prevent leaks and maintain system pressure.
Sold individually
Fits:
O-Ring 99970751741 is widely used across multiple Porsche models, including:
Porsche Cayenne (955 / 9YA)
Porsche Panamera (971 / 976)
This O-ring is commonly used across a wide range of Porsche models and is essential when removing or reinstalling coolant pipes, housings, or related components. As with all sealing elements, it should always be replaced during servicing to ensure optimal performance and prevent future leaks.
Fitment & Application:
• Suitable for various Porsche models
• Commonly used in engine cooling systems
• Function: Prevents coolant leaks and maintains system pressure
• Position: Coolant pipes / hose connections / housing joints
• Size: 22 mm inner diameter x 3 mm thickness
• Sold: Individually
Cross Reference / Superseded Numbers: 99970751740 - replaced by 99970751741
Coolant system O-rings are exposed to constant heat and chemical exposure, causing them to harden, crack, or lose elasticity over time. A failing seal can lead to coolant leaks, overheating, and potential engine damage. Replacing O-rings during servicing ensures proper sealing, prevents leaks, and maintains reliable cooling system operation.
When to replace
• During coolant pipe or housing removal
• Visible coolant leaks or residue
• O-ring appears flattened, brittle, or cracked
• Preventative replacement during cooling system service
• After engine overheating incidents
