Radiator for water coolant fluid. Porsche Boxster 987 / Cayman 987C / 997 (OE Part No. 99710613102 / 99710613202)  ❭  99710613

Radiator for water coolant fluid.
Radiator for water coolant fluid (also known as Coolant radiator, Water radiator or Water coolant fluid cooler) is the backbone of a Porsche engine’s thermal management system. It dissipates heat from the engine’s water-based coolant, stabilising engine temperatures, preserving performance, efficiency, and long-term reliability.

Fits:
Porsche 987 Boxster - 2005 to 2012
Porsche 987C Cayman - 2005 to 2012
Porsche 997 - 2005 to 2012

The radiator’s main role is to remove heat from the engine coolant that carries thermal energy away from the engine block and cylinder head. Hot coolant flows into the radiator, where it travels through a series of fine tubes and cooling fins. Air passing through the radiator core (from vehicle motion and fans) absorbs the heat, lowering coolant temperature before it returns to the engine.

Proper heat rejection helps:
•  Maintain optimal engine operating temperature
•  Prevent overheating under everyday and high-load conditions
•  Support fuel efficiency and emission control
•  Preserve engine component durability and longevity
