Diagram Ref No 1.

Designed specifically for the water-cooled V8 engines used in the Porsche 928, the radiator features a high-efficiency core that allows heat from the circulating coolant to be transferred into airflow passing through the front grille.

Constructed from durable materials (typically aluminium core with reinforced end tanks), it is built to withstand high temperatures, pressure, and long-term exposure to coolant. It integrates seamlessly with factory hoses, fans, and mounting points. 

 The radiator removes excess heat from engine coolant, preventing overheating and ensuring stable engine operation. It allows the engine to maintain the correct temperature range, which is critical for performance, efficiency, and longevity.

A properly functioning radiator ensures consistent cooling even under demanding driving conditions.

Function
• Dissipates heat from engine coolant
•  Maintains optimal engine operating temperature
•  Prevents overheating and thermal damage
•  Supports efficient engine performance and longevity

Over time, radiators can become clogged, corroded, or develop leaks due to age and coolant degradation. Reduced cooling efficiency can lead to overheating, which may cause serious engine damage. Replacing the radiator restores proper cooling performance, protects engine components, and ensures reliable operation - especially important for classic Porsche vehicles.

When to replace
•  Engine overheating or running hot
•  Coolant leaks from radiator or seams
•  Visible corrosion or damaged fins
•  Blocked or restricted coolant flow
•  During cooling system overhaul
