Diagram ref no 1
The water radiator helps remove heat from the engine coolant as it circulates through the cooling system. By transferring heat from the coolant to the surrounding airflow, the radiator helps maintain stable engine operating temperature and protects the engine from overheating.
Functions
• Replaces the left or right water coolant radiator
• Helps dissipate heat from the engine coolant
• Supports stable engine operating temperature
• Maintains correct cooling system performance
• Helps prevent overheating and coolant temperature issues
• Replaces leaking, blocked, corroded, or damaged original radiators
• OE Match replacement for cooling system repair and maintenance.
Why Replace This Part?
Radiators are exposed to heat, pressure, coolant additives, road debris, moisture, corrosion, and vibration. Over time, the radiator core can become blocked, corroded, damaged, or start to leak. A faulty radiator may cause coolant loss, overheating, low coolant warnings, poor cooling performance, or visible coolant staining. Replacing the radiator helps restore efficient heat transfer and reliable cooling system operation.
When to Replace This Part
• The radiator is leaking, corroded, blocked, or damaged
• Coolant staining or seepage is visible around the radiator
• The vehicle has low coolant warnings or overheating symptoms
• The radiator core fins are crushed, clogged, or deteriorated
• The front cooling system has suffered impact or road debris damage
• Coolant hoses, clamps, or related cooling parts are being replaced
• Preventative replacement is being carried out during cooling system overhaul.
Where it fits on the car
These radiators fit in the left and right front radiator positions within the cooling system on Porsche 991.2, 982 Boxster, and 982C Cayman models. Each radiator connects to the coolant hose circuit according to the factory cooling system layout.

Information
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 987.1 Boxster 2005 - 2008
Porsche 987.2 Boxster 2009 - 2012
Porsche 987C.1 Cayman 2005 - 2008
Porsche 987C.2 Cayman 2009 - 2012
Porsche 997.1 Carrera 2005 - 2008
Porsche 997.1 GT3 2007 - 2009
Porsche 997.2 Carrera 2009 - 2012
Porsche 997.2 GT3 2010 - 2011
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
