Centre radiator for water coolant fluid. Porsche Boxster 986 / 996  ❭  99610603753

Centre 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 986 Boxster 3.2L 2000 - 2004
Porsche 996 C2 / C4 / C4S / GT3 1998 - 2005

This product supersedes Porsche's old part numbers:  99610603750, 99610603751, 99610603752

Diagram Ref No 1.

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
