Information
Engine coolant expansion tank kit with sensor.
This is a comprehensive OE Match-quality service kit designed to refresh and restore the engine coolant expansion system for Porsche vehicles. It includes the expansion tank, pressure cap, long-life antifreeze, and a coolant level sensor - giving you all major components needed for a proper coolant system service.
Fits:
Porsche 996 C2 / C4 1997 - 2000
Porsche 996 GT3 MKI 1997 - 2000
Diagram ref no 1, 2, 3, 4, 5, 9, 11, 12.
This engine coolant expansion tank kit brings together all the essential components that ensure your Porsche’s coolant system works efficiently and reliably:
• 1x 99610614756/1 – OE Match Coolant Expansion Tank Bottle: A high-quality OE Match reservoir that captures overflow and maintains appropriate coolant volume.
• 1x 99610644704/1 – OE Match Expansion Tank Cap: Maintains correct cooling system pressure to optimize thermal performance.
• 5x 00004330194 – Comma 1 L Antifreeze Concentrate (Red, 5-Year): Long-life coolant concentrate to mix with distilled water, offering corrosion protection and thermal stability.
• 1x 99764150300/1 – OE Match Coolant Level Sensor: Monitors coolant level inside the expansion tank and alerts the driver if the level drops too low.
Together, these items create a complete cooling system refill and monitoring kit.
This kit refurbishes the coolant expansion side of the cooling system. The expansion tank stores excess coolant when the engine heats up and returns it as it cools. The pressure cap ensures the system operates at the correct pressure, which increases coolant boiling point and improves efficiency. The included coolant provides balanced antifreeze protection and corrosion resistance for years, while the sensor keeps track of coolant level and triggers warnings if levels fall below safe thresholds.
Over time, plastic coolant expansion tanks can become brittle, cracked, or distorted, leading to leaks and loss of coolant. A weak pressure cap can fail to maintain proper system pressure, reducing cooling effectiveness. Old coolant can lose its protective qualities, leading to corrosion and overheating. Without a functioning coolant level sensor, you may not be alerted to low coolant levels, increasing risk of engine overheating or damage. This kit replaces all of these important parts at once, restoring correct operation and helping ensure the engine stays well-protected.
Replace any of these components if you observe the following:
• Cracks, leaks, or deformation in the expansion tank.
• A non-sealing or failing pressure cap.
• Coolant looks discoloured, sludgy, or contaminated.
• Dashboard warning light for coolant level.
• Regular service interval for coolant change is due.
• Unexplained engine temperature fluctuations.
