The kit helps restore the main front cooling circuit by replacing key radiator and coolant hose components. The radiators dissipate heat from the coolant, while the hoses, clamps, and O-rings help maintain coolant flow, system pressure, and leak-free connections throughout the cooling system.

Functions
•  Replaces the left and right coolant radiators
•  Includes left and right coolant hoses for feed and return positions
•  Supports correct coolant circulation through the radiator circuit
•  Helps maintain stable engine operating temperature
•  Helps prevent coolant leaks, pressure loss, and overheating
•  Includes clamps and O-rings for secure hose and pipe sealing
•  OE Match replacement kit for cooling system repair and maintenance.

Why Replace This Kit?
Radiators, hoses, clamps, and O-rings are exposed to heat, pressure, road debris, moisture, coolant additives, vibration, and age-related wear. Over time, radiators can corrode, block, leak, or suffer impact damage, while hoses can crack, swell, split, or harden. Clamps may lose tension or corrode, and O-rings can flatten, perish, or leak. Replacing these components together helps restore reliable cooling system performance and reduces the risk of repeated coolant leaks.

When to Replace This Kit
•   One or both radiators are leaking, corroded, blocked, or damaged
•   Coolant hoses are cracked, swollen, soft, brittle, or split
•   Coolant leaks are visible around radiator, hose, or pipe connections
•   The vehicle shows low coolant warnings or overheating symptoms
•   Front cooling system components have suffered impact or road debris damage
•   The cooling system is being overhauled or preventative maintenance is being carried out
•   Clamps and O-rings are being replaced to ensure secure sealing during radiator work.

Where it fits on the car
This kit fits within the front radiator and coolant hose circuit on Porsche 991.2, 982 Boxster, and 982C Cayman models. The left and right radiators fit in their respective radiator positions, while the included hoses, clamps, and O-rings support the coolant feed and return connections.
