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.
Sold individually, 3 required per car
Fits:
Porsche 911 1984 - 1989
Diagram Ref No 14.
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 replacement buffer is a high-quality replacement for the factory bonded-rubber mounts used to support the oil cooler assembly in air-cooled Porsche engines. It helps isolate vibration, maintain correct alignment, and protect the cooler and adjoining hardware.
Sold each, required 3 per car.
Fits:
Porsche 911 1984 - 1989
Diagram Ref No 14.
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.

Engine Oil Coolers, Radiators & Heat Exchangers – Precision Cooling for Porsche Performance
The engine oil cooler and heat exchanger system plays a critical role in managing temperature within your Porsche’s engine. By transferring excess heat away from the oil and other fluids, these components ensure stable operating temperatures, consistent lubrication, and maximum engine longevity — especially under demanding performance conditions.
At Design911, we offer a full range of engine oil coolers, radiators, and heat exchangers for Porsche models old and new. Built from high-efficiency aluminium or reinforced composite materials, these components are designed to deliver superior cooling performance, durability, and perfect fitment — ensuring your Porsche performs at its best, on road or track.
Whether replacing a worn-out unit or upgrading for improved thermal efficiency, our oil cooling components provide reliable temperature control and enhanced performance.
What Do Engine Oil Coolers, Radiators & Heat Exchangers Do?
These components regulate oil and engine temperatures to maintain optimal performance and prevent overheating.
Core Functions:
- Dissipate
excess heat from the engine oil, coolant, or transmission fluid.
- Maintain
consistent oil viscosity and prevent breakdown under load.
- Protect
internal engine components from heat-related wear and failure.
- Improve overall performance efficiency during extended drives or track sessions.
Together, the oil cooler, radiator, and heat exchanger form an essential thermal management system, helping your Porsche run at peak performance while protecting vital components.
Why Do Oil Coolers & Heat Exchangers Fail?
Over time, exposure to heat cycles, vibration, and contaminants can lead to efficiency loss or complete failure.
Common Causes of Failure Include:
- Corrosion
or cracking from age or road debris impact.
- Internal
clogging caused by sludge or contaminated oil.
- Leaking
seals or fittings, reducing pressure and fluid efficiency.
- Thermal
fatigue, leading to reduced cooling capacity.
- Poor maintenance or coolant neglect, accelerating deterioration.
Symptoms of failure can include high oil temperatures, oil leaks, coolant contamination, or reduced engine performance, all of which signal the need for inspection or replacement.
Why Replace Oil Cooling Components?
Replacing a worn or leaking oil cooler, radiator, or heat exchanger is essential to preserve lubrication quality and prevent costly overheating damage. Our precision-fit, high-durability components restore proper cooling balance and reliability under all conditions.
Key Benefits:
- Restores efficient oil and fluid temperature regulation.
- Prevents overheating and engine wear.
- Improves reliability under heavy load or track use.
- Constructed from corrosion-resistant, high-performance materials.
- Direct-fit compatibility for classic and modern Porsche engines.
- Ideal for rebuilds, maintenance, and performance upgrades.
Upgrading or replacing your cooling system components helps ensure your Porsche’s engine stays efficient, durable, and ready for spirited driving.
Highlights:
- Comprehensive range of Porsche oil coolers, radiators, and heat exchangers.
- Precision-engineered for consistent temperature control.
- Constructed from lightweight, corrosion-resistant materials.
- Designed for reliability in both road and motorsport conditions.
- Improves lubrication and protects engine performance.
- Perfect for maintenance, rebuilds, or performance enhancements.
