This OE Genuine Porsche kit is designed for Porsche models that use part number 99610615704 for the coolant expansion reservoir - commonly found on Porsche 911 (996 & early 997) vehicles from roughly 2001-2012. Always verify specific model and year compatibility before installation.
This service kit combines essential Genuine Porsche components engineered to work together for optimal cooling system performance:
• 99610615704 × 1 – Genuine Porsche Coolant Expansion Tank: Factory-designed coolant reservoir that collects expanding coolant as engine temperatures rise and returns it as the system cools. Built to exact Porsche OE specifications for perfect fit and long service life.
• 99610644704 × 1 – Genuine Porsche Expansion Tank Cap: Original equipment pressure cap that seals the reservoir and maintains correct cooling system pressure for efficient thermal control.
• 99764150300 × 1 – Genuine Porsche Coolant Level Sensor: Factory fluid level sensor ensures accurate monitoring of coolant level and integrates with the vehicle’s onboard warning system for enhanced safety.
• 00004330515 × 5 – Genuine Porsche Long-Life Antifreeze (1 L, Red, 5-Year Protection): Factory-approved coolant concentrate formulated to deliver extended thermal protection and corrosion resistance when mixed with distilled water.
Together, these parts create a comprehensive cooling system refresh kit designed to restore and maintain proper coolant management under all driving conditions.
Over time, the original coolant expansion tank can become brittle, discoloured, or cracked due to repeated heat cycling and chemical exposure, potentially leading to leaks, reduced pressure control, and poor cooling performance. Old or degraded coolant loses its protective properties, increasing the risk of corrosion and overheating. Failing to replace worn parts can result in costly engine damage. Using Genuine Porsche parts ensures factory-original fit, dependable performance, and long-term reliability - preserving engine health and cooling efficiency.
Replace this kit when you notice any of the following:
• Cracks, leaks or deformation in the expansion tank
• Pressure cap no longer seals or maintains system pressure
• Coolant appears contaminated, sludgy or past its service life
• Frequent coolant top-ups are required without visible external leaks.
