This is a Genuine Porsche parts kit comprising essential cooling system components for vehicles that use 99610614756 as the engine coolant expansion tank. Genuine parts ensure exact fit and preserved factory-engineered performance and durability.

Kit Includes:
• 99610614756 × 1 – Genuine Porsche Engine Coolant Expansion Tank: Factory reservoir that manages coolant overflow as temperatures change.
• 99610644704 × 1 – Genuine Porsche Expansion Tank Cap: Maintains correct cooling system pressure and seals the reservoir effectively.
• 00004330515 × 5 – Genuine Porsche Antifreeze/Coolant (1 L Bottles, Red, Long-Life): Porsche-approved coolant concentrate that delivers thermal protection and corrosion resistance when mixed correctly with distilled water.
• 99764150300/1 × 1 – Genuine Porsche Coolant Level Sensor: Factory-specified sensor that monitors coolant level inside the expansion tank and alerts the driver of low coolant.

Together, these parts refresh or restore the cooling system’s expansion reservoir side, ensuring proper coolant containment, pressure control, and system monitoring.

Over time, factory expansion tanks and caps can brittle, crack, or lose sealing integrity due to heat cycling and coolant chemistry, leading to leaks, pressure loss, and potential engine overheating. Old coolant may also degrade, losing its protective properties. The coolant level sensor may fail or give false readings if worn. Replacing all of these with Genuine Porsche components ensures continued cooling system integrity, accurate level monitoring, and reliable performance over time.

Replace components in this kit when you observe any of the following:
•  Cracks, distortion, or coolant leaks around the tank
•  Expansion tank cap no longer seals or holds pressure
•  Coolant appears contaminated, discoloured, or degraded
•  Dashboard warning of low coolant level
•  Routine service interval for coolant system maintenance
