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.

The OE Match Fan Temperature Switch, 2 Pin is a high-quality replacement cooling system component designed to activate the radiator cooling fan when coolant temperatures reach a predetermined level. Mounted within the cooling system, this switch monitors coolant temperature and automatically signals the electric cooling fan to operate when additional cooling is required.

Manufactured to OE specifications for fit, function and reliability, this 2-pin temperature switch helps maintain correct engine operating temperatures, protects against overheating and ensures efficient cooling system performance. It is an essential replacement item for maintaining the reliability of the vehicle's cooling system.
What This Product Does:
- Monitors coolant temperature within the cooling system.
- Activates the electric radiator cooling fan when required.
- Helps maintain optimum engine operating temperature.
- Prevents excessive heat build-up during low-speed driving or idling.
- Supports efficient cooling system operation.
- Protects the engine from overheating-related damage.
Symptoms Of Wear Or Failure:
- Cooling fan fails to operate when the engine reaches operating temperature.
- Engine temperature rises higher than normal.
- Engine overheating during traffic or idle conditions.
- Cooling fan runs continuously regardless of temperature.
- Inconsistent cooling fan operation.
- Temperature warning light activation.
- Reduced cooling system efficiency.
- Overheating during warm weather or heavy traffic conditions.
Why Replacement Matters:
- The fan temperature switch plays a critical role in controlling cooling fan operation and maintaining stable engine temperatures. Over time, repeated heat cycles, age and electrical wear can affect the switch's ability to accurately detect coolant temperature and activate the fan.
- A failed switch can prevent the cooling fan from operating when needed, significantly increasing the risk of overheating. Excessive engine temperatures can damage gaskets, seals, cooling system components and, in severe cases, major engine components.
