Key Features

• Direct replacement rubber-metal mounting buffer
• Suitable for Porsche 928 and 928S (1980–1986)
• Designed for radiator fan blower guard grille mounting
• Reduces vibration and noise within the cooling system
• Durable rubber-metal bonded construction

Function and Purpose

This mounting buffer provides secure attachment and vibration isolation for the radiator fan assembly components.

It helps to:

• Stabilise the blower guard grille and fan assembly
• Reduce vibration transfer within the cooling system
• Minimise noise caused by component movement
• Protect surrounding components from wear and stress

Why Replace Your Radiator Fan Mounting Buffer

Over time, rubber-metal mounts can degrade due to heat and vibration.

Common issues include:

• Cracked or hardened rubber
• Reduced vibration damping performance
• Loose or unstable fan assembly components
• Increased noise or movement in the cooling system

Replacing the buffer restores proper mounting stability and cooling system performance.
