Radiator Fan Mounting Rubber Buffer – Blower Grille Mount
Sold each - 2 required per car
High-quality rubber-metal mounting buffer designed for securing the radiator fan blower guard grille on Porsche 928 and 928S models (1980–1986).
This component acts as a vibration-damping mounting point,
ensuring the blower guard grille and associated fan assembly are securely
positioned while reducing vibration and noise within the cooling system.
Fits:
- Porsche 928 4.5L 1980-82
- Porsche 928S 4.7L 1981-83

Constructed using a durable rubber-metal bonded design, this mounting buffer is engineered to withstand engine bay temperatures, mechanical stress, and long-term use while maintaining flexibility and structural integrity.
A direct replacement part, this radiator fan mounting buffer is essential for maintaining proper cooling system stability and preventing unwanted movement or wear.
Reference Number: 99970331000
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
• OEM-style fit and function
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.

The radiator functions as the primary heat exchanger in the vehicle’s cooling system. Coolant heated by the engine flows through the radiator’s tubes and fins, where it relinquishes heat to the surrounding air as it passes through. This heat transfer process is essential to prevent overheating, maintain ideal combustion conditions, protect internal engine components, and ensure consistent performance.
Function:
• Dissipates thermal energy from engine coolant via a network of tubes and cooling fins
• Works with the cooling fan and shroud assembly to optimise airflow and cooling efficiency
• Maintains stable engine operating temperatures under varying load and ambient conditions
• Ensures long-term reliability and protects the engine from heat-related wear or damage.
Genuine Porsche radiators are constructed from durable materials designed to withstand constant temperature changes, road vibration, and corrosion, ensuring sustained performance over time.
