Information
Engine coolant expansion tank kit.
This kit includes the expansion tank reservoir, pressure cap, and multiple bottles of genuine Porsche coolant/antifreeze - everything needed for a full coolant system refresh
Fits:
Porsche 996 C2 / C4 1997 - 2000
Porsche 996 GT3 MKI 1997 - 2000
Diagram ref no 1, 3, 4, 5, 9, 11, 12.
This kit is suitable for Porsche models that use part 99610614756 as the coolant expansion tank reservoir.
Kit Includes:
• 99610614756 × 1 - Genuine Porsche Coolant Expansion Tank Bottle: Factory-spec reservoir engineered to handle coolant expansion and contraction as engine temperatures fluctuate.
• 99610644704 × 1 - Genuine Porsche Expansion Tank Cap: Provides reliable system pressure control in the cooling system to maintain boiling point and prevent coolant loss.
• 00004330515 × 5 - Genuine Porsche Antifreeze Coolant 1 Litre (Red, Long Life, 5-Year Protection): High-quality coolant concentrate designed to be mixed 50/50 with distilled water for excellent heat transfer, freeze/boil protection, and corrosion resistance.
This kit restores key components of the engine’s coolant reservoir system. The expansion tank collects and stores excess coolant as it expands during heating, the pressure cap maintains proper system pressure to raise the coolant’s boiling point, and the antifreeze delivers long-lasting thermal protection and corrosion control. Using genuine Porsche coolant ensures fluid chemistry is matched to factory specifications.
With age and heat cycling, the original expansion tank and cap can become brittle, cracked, or unable to maintain proper pressure, leading to coolant loss, air ingress, and potential overheating issues. Using genuine Porsche coolant ensures the fluid meets manufacturer chemistry standards for corrosion protection and performance. Replacing these components with genuine parts helps restore the cooling system’s integrity and protects the engine from thermal stress and premature wear.
Replace these components if you notice any of the following:
• Visible cracks, leaks, or discoloration on the expansion tank
• Pressure cap that no longer seals properly
• Coolant that looks contaminated or past its service life
• Unexplained coolant loss or coolant level fluctuations
• Scheduled cooling system maintenance interval reached

Information
Water Reservoir Bleeder Valve
The water reservoir bleeder valve (7P5121671A / A1216152) is a key cooling
system component that regulates pressure and allows trapped air to escape from
the expansion tank. By ensuring consistent coolant circulation and correct
pressure balance, it prevents overheating and maintains long-term engine
reliability.
