Information
Engine coolant expansion tank kit.
The kit combines a coolant expansion tank, a pressure cap, and long-life antifreeze concentrate to deliver a complete 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 comprehensive kit includes the essential parts needed when servicing or replacing the coolant expansion system on Porsche models that use part number 99610614756. An OE Match expansion tank provides a direct fit and correct performance:
• 1x 99610614756/1 – OE Match Coolant expansion tank - for correct fit & durability.
• 1x 99610644704/1 – OE Match Coolant expansion tank pressure cap - to hold system pressure and prevent boiling/overflow.
• 5x 00004330194 – Comma Concentrated Long-Life Red Antifreeze / Coolant - for optimal cooling & corrosion protection.
This kit refreshes the entire coolant expansion side of the cooling system. The expansion tank collects excess coolant and allows it to return to the system as temperatures change. The pressure cap controls system pressure, raising coolant boiling point and preventing air ingress. The antifreeze bottles supply corrosion protection, freezing/boiling point stability, and long-term fluid protection when mixed and filled.
A worn or failing expansion tank can crack, leak or lose pressure, leading to coolant loss, overheating, and potential engine damage over time. The pressure cap also plays a critical role: an old or weak cap can fail to hold sufficient system pressure, lowering coolant boiling point and reducing cooling efficiency. Fresh antifreeze not only prevents freezing/boiling extremes but also protects metal parts from corrosion, improving overall engine health and heat management.
Replace components when you notice any of the following:
• Coolant reservoir shows cracks, swelling, brittleness or leaks.
• Coolant fluid levels change unexpectedly without visible leaks.
• Pressure cap no longer maintains correct system pressure.
• Coolant appears contaminated, sludgy, or discoloured.
• Recommended coolant change interval (e.g., every 2–5 years) is due.
