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.

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
