Diagram ref no 1

Designed for the factory front cooling arrangement, it provides an OE replacement for a leaking, damaged or inefficient original centre radiator.

Key Features

• Genuine Porsche centre water/coolant radiator.
• Designed for selected high-performance Porsche 991 and 981 models.
• Supports efficient heat dissipation and engine temperature control.
• Forms part of the front-mounted radiator cooling system.
• Helps maintain correct coolant circulation and cooling performance.
• Replaces a leaking, corroded or damaged original radiator.
• Manufactured to Porsche's original fitment specification.

Why Replace This Part?
The centre radiator is exposed to road debris, moisture, corrosion and repeated temperature changes. Over time, the radiator core can become damaged or blocked, while ageing connections and seals may contribute to coolant leaks. A faulty radiator can reduce cooling efficiency and increase the risk of engine overheating, particularly during demanding driving conditions.

Replacing it with a Genuine Porsche centre radiator helps restore the original cooling system performance.

Common Symptoms of a Faulty Radiator

• Coolant leaking from the front centre radiator area.
• Low coolant warning.
• Engine temperature rising above normal.
• Damaged or corroded radiator core.
• Bent or blocked cooling fins.
• Dried coolant residue around radiator connections.
• Cooling system pressure loss.
• Reduced cooling efficiency during demanding driving.

Where It Fits on the Car
The radiator is fitted in the front centre cooling assembly, behind the front bumper. It works alongside the vehicle's other radiators, coolant hoses and associated cooling system components.
