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.

Front Radiator Engine Oil Cooler "Snake Type"
Restore efficient oil temperature control to your classic
air-cooled Porsche with this OE Match Front Radiator Engine Oil Cooler. Better known as the Snake Type Oil Cooler
or Trombone Oil Cooler, this OE-quality replacement is designed to match
the original equipment fitted to Porsche 911 models.

Positioned within the front right-hand wheel arch, the Trombone Oil Cooler forms an integral part of Porsche's legendary dry sump lubrication system. Its distinctive looped tube design increases the surface area exposed to airflow, allowing engine oil to dissipate heat before returning to the oil tank. Although simple in construction compared to later finned radiator-style coolers, the Trombone Oil Cooler proved to be an effective and reliable solution for controlling engine oil temperatures in early impact bumper 911s and first-generation 930 turbos.
Manufactured to OE Match specifications, this replacement offers factory-correct fitment, dependable performance and excellent durability, making it the ideal choice for restorations, preventative maintenance and originality-focused repairs.
What Does the Snake Type (Trombone) Oil Cooler Do?
Unlike water-cooled engines, air-cooled Porsche engines rely
heavily on engine oil to remove heat as well as lubricate internal components.
The front-mounted Trombone Oil Cooler helps to:
- Reduce engine oil temperatures.
- Improve heat dissipation during sustained driving.
- Maintain stable oil viscosity.
- Protect pistons, bearings and internal engine components.
- Improve engine reliability during hot weather and spirited driving.
- Extend engine life by maintaining consistent operating temperatures.
By cooling the oil before it returns to the engine, the Trombone Oil Cooler plays a vital role in preserving the health of your classic flat-six engine.
Why Do Trombone Oil Coolers Need Replacing?
After decades of service, the original oil cooler may suffer
from:
- External corrosion caused by moisture and road salt.
- Stone damage from debris entering the wheel arch.
- Impact damage.
- Internal contamination.
- Fatigue cracks or pinhole leaks.
- Damage caused during previous repairs.
- Reduced cooling efficiency due to age.
Even a minor oil leak can lead to falling oil pressure and increased engine temperatures, making timely replacement essential.
Symptoms of a Failing Oil Cooler
Common warning signs include:
- Engine oil leaks around the front wheel arch.
- Oil residue on the cooling loop.
- Rising engine oil temperatures.
- Burning oil smell after driving.
- Visible corrosion or physical damage.
- Reduced cooling performance.
- Falling oil level without obvious engine leaks.
Any evidence of oil leakage should be investigated immediately to prevent costly engine damage.
When Should the Oil Cooler Be Replaced?
Replacement is recommended when:
- Oil leaks develop.
- The cooling loop becomes corroded or damaged.
- Accident damage has occurred.
- Restoring a classic Porsche to factory condition.
- Replacing front oil pipes or oil lines.
- Carrying out a complete engine rebuild or lubrication system overhaul.
Replacing ageing oil cooling components helps maintain optimum lubrication and protects your engine for years to come.
