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

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
Diagram ref no 6
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.

OEMatch Water / Coolant Radiators — Fit, Function, Confidence
OEMatch supplies water and coolant radiators for Porsche models. Radiators control engine temperature by transferring heat from coolant to air, helping to prevent overheating and limiting thermal stress on engine components. This overview explains common types, failure modes and what to check when a Porsche radiator needs replacement.
Available Types
- Aluminium-core radiators with welded construction for efficient heat transfer
- Radiators with reinforced end tanks for higher-load or heavy-use applications
- Application-specific units for transaxle and front-engine Porsche models, including designs tuned for cooling capacity and packaging
Understanding OEMatch Water / Coolant Radiators
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original water and coolant radiators. OE (Original Equipment) refers to parts matching original specifications for the water and coolant radiators and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM water and coolant radiators engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
Radiators move heat from the engine coolant into the airstream via a core of tubes and fins; end tanks and joints direct flow and sustain pressure. Materials and construction influence resistance to corrosion, mechanical damage and thermal cycling. OEMatch catalogues thousands of part numbers and OE cross-references to support coverage across Porsche model lines and continues to expand its range for long-term vehicle support.
Benefits Include
- Restored cooling efficiency and consistent engine temperature control
- Reduced risk of overheating and related engine damage
- Improved longevity through corrosion-resistant materials and quality joins
Why Water / Coolant Radiators Wear and Fail
- Corrosion and internal scale from old or contaminated coolant
- Leaks from cracked tanks, damaged cores or failed seals and joints
- Blockages caused by debris, oil contamination or coolant breakdown products
- Physical damage from road debris or impact
The Importance of Replacing with OEMatch Water / Coolant Radiators
A compromised radiator reduces cooling capacity and raises the risk of overheating, which can lead to costly engine repairs and degraded performance. Choosing a replacement designed for Porsche applications restores correct coolant flow and heat transfer, maintains engine operating temperature and supports reliable day-to-day use and spirited driving alike.
Advantages
- Aluminium cores and precision joins that support efficient heat exchange
- Reinforced end tanks and durable connections for leak resistance
- Manufactured to original-spec dimensions and tolerances so fitment aligns with factory mounting and cooling system routing
Support & Advice
These items affect safety-critical systems. Installation should be carried out by a qualified technician following model-specific procedures and torque settings. Use calibrated tools and new fasteners where specified, and confirm correct hose connections, clamps and coolant specification after fitting.
