What This Kit Does
The Porsche 991 Turbo cooling system uses multiple front-mounted radiators to help regulate engine operating temperature. The centre radiator provides additional cooling capacity by transferring heat from the circulating coolant to the surrounding airflow. The connecting coolant hoses maintain coolant flow through the radiator, while the upper and lower rubber mountings secure the radiator in position and help isolate vibration. Replacing these components together helps restore the original cooling system arrangement.

Key Features
  • Complete centre radiator replacement package.
  • Suitable for selected Porsche 991 Turbo and Turbo S models.
  • Includes one centre coolant radiator.
  • Includes both centre radiator connecting hoses.
  • Supplied with two upper and two lower rubber mountings.
  • Helps restore coolant circulation and cooling efficiency.
  • Replaces worn, leaking or damaged original cooling components.
  • Ideal for radiator repairs, front-end restoration and cooling system maintenance.

Why Replace This Kit?
Radiators and coolant hoses are exposed to repeated heat cycles, cooling system pressure, vibration and road debris. Over time, radiator cores may become corroded or damaged, coolant hoses can deteriorate and rubber mountings may harden or split.

Replacing the centre radiator, hoses and mountings together reduces the risk of retaining worn components during a major cooling system repair.

Common Reasons for Replacement
  • Coolant leaking from the centre radiator.
  • Cracked or damaged radiator core.
  • Deteriorated coolant hoses.
  • Low coolant warning.
  • Cooling system pressure loss.
  • Damaged or compressed rubber mountings.
  • Front bumper or radiator impact damage.
  • Reduced cooling performance.
  • Complete centre radiator refurbishment.

Where It Fits on the Car
This kit fits within the front centre radiator assembly, behind the front bumper. The radiator connects to the engine cooling circuit through the supplied coolant hoses and is supported by the upper and lower rubber mounting bushes.
