The Porsche 93020723900 / 93020723901 / 93020723902 Bonded Rubber Buffers are factory-original components designed to mount and stabilize the oil cooler assembly in air-cooled Porsche 911 and Turbo models. Each mount uses a precision-bonded rubber and steel design that isolates vibration and absorbs engine movement, protecting the oil cooler and its lines from stress and damage.

Located between the oil cooler housing and the chassis or engine bracket, these buffers play a vital role in maintaining correct alignment and reducing vibration throughout the cooling system. Over time, exposure to heat, oil, and vibration can cause the rubber to harden or crack. Replacing with genuine Porsche parts restores factory stability, vibration isolation, and long-term reliability.

This is a rubber buffer or mount (often bonded to metal inserts) used to cushion and secure the oil cooler assembly relative to the engine or chassis. It absorbs vibration, prevents metal-to-metal contact, and keeps the cooler in its correct position. It helps avoid stresses on oil cooler brackets, lines, and mating surfaces by providing a flexible mounting point.
Replaces: Porsche 930.207.239.00 / 930.207.239.01 / 930.207.239.02
Position: Between oil cooler and engine or chassis mount — isolates vibration and supports alignment
Function: Absorbs vibration and engine movement, prevents stress on oil cooler lines and brackets
Installation: Direct-fit OE replacement — install as a set for best results
Maintenance Tip: Replace when rubber hardens, cracks, or separates from metal housing
Over time, the rubber in the buffer mount degrades due to heat, oil exposure, ozone, vibration, and fatigue. It may harden, crack, shrink, or separate from its bonded metal insert. A failed mount lets the oil cooler shift or vibrate more than designed, putting strain on cooler hoses, brackets, and mounting flanges — potentially leading to leaks or damage. Excessive vibration may cause noise, misalignment, or premature fatigue of supporting parts. You should replace this buffer when you notice damage or deterioration, when removing or servicing the oil cooler, or as preventive maintenance on high-mileage engines.

This radiator oil cooler rubber mount is an replacement rubber isolator designed to support the radiator oil cooler on classic Porsche 911 models 1978–1989.
It cushions and secures the radiator oil cooler within the engine bay, reducing vibration and noise while helping maintain correct positioning of the cooler assembly. It matches original factory specifications so it installs directly into the intended mounting points with no modification required.
Sold each.
Fits:
Porsche 911 1978 - 1989
Diagram ref no 13B
The rubber mount absorbs engine and road vibration, helping to isolate the oil cooler from harsh movement and protect it from stress and fatigue. It keeps the cooler properly aligned, preventing undue strain on hoses, fittings, and brackets.
Built to support the weight of the radiator oil cooler and dampen dynamic forces, this mount mitigates vibration transfer throughout the engine bay. It ensures the oil cooler remains stable under thermal expansion, engine torque, and chassis motion while helping minimise noise and wear.
Over time, rubber mounts deteriorate from heat, age, and exposure to oil and road contaminants. A worn or broken mount can allow excessive cooler movement, leading to hose fatigue, oil leaks, and compromised cooling performance. Replacing it with an OE-match mount restores proper support and prolongs the life of your oil cooler system.
When to replace:
• Visible cracks, splits, or deformation in the rubber
• Loose or sagging radiator oil cooler
• Increased vibration or noise from the engine compartment
• During oil cooler removal or engine work
• As part of preventive maintenance

Oil Radiators & Heat Exchangers – Optimal Temperature Control for Porsche Performance
Oil radiators and heat exchangers are crucial components in your Porsche’s engine and transmission cooling systems. They regulate oil temperature by transferring heat away from the lubricating or hydraulic fluids, ensuring consistent performance, efficient lubrication, and long-term engine protection — even under extreme driving conditions.
At Design911, we offer a complete range of genuine and manufacturer-quality oil radiators and heat exchangers for Porsche models including 911, Boxster, Cayman, Cayenne, Macan, and Panamera. Each unit is engineered for precise fitment, efficient heat transfer, and long-lasting reliability — maintaining the high-performance standards that Porsche vehicles are known for.
What Do Oil Radiators & Heat Exchangers Do?
Oil radiators and heat exchangers serve a vital role in
temperature regulation and system protection. They:
- Dissipate
heat from engine or transmission oil to prevent overheating.
- Maintain
stable oil temperature for optimal viscosity and lubrication.
- Extend
component lifespan by preventing thermal damage.
- Support engine and gearbox efficiency under heavy load or high-speed conditions.
By controlling oil temperatures, these parts ensure consistent power delivery, reduced wear, and greater reliability — whether on the road or track.
Why Do Oil Radiators & Heat Exchangers Fail?
Despite being built to handle extreme conditions, these
components can fail over time due to wear, corrosion, or contamination. Common
causes include:
- Corrosion
or internal blockage from debris or degraded fluids.
- Physical
damage from road debris or impact.
- Oil
or coolant leaks due to cracked housings or seals.
- Reduced
heat transfer efficiency from clogged fins or internal scaling.
- Age-related deterioration of internal passages or gaskets.
Symptoms of failure include oil leaks, rising engine temperatures, reduced oil pressure, or contamination between the oil and coolant systems.
Why Replace a Faulty Oil Radiator or Heat Exchanger?
A damaged or inefficient oil radiator can cause overheating, loss of lubrication, and serious engine or transmission damage. Replacing faulty units restores cooling efficiency and ensures your Porsche continues to deliver peak performance and reliability.
Benefits of replacement include:
- Restored oil temperature control and pressure stability.
- Prevention of overheating and oil contamination.
- Improved engine and gearbox longevity.
- Manufacturer-quality construction and fitment for peace of mind.
Each radiator and heat exchanger in this range is designed to meet or exceed factory standards, using advanced materials and precision manufacturing for superior durability, corrosion resistance, and cooling performance.
