Radiator Engine Oil Cooler Front "Snake Type"
Maintain the correct operating temperature of your classic
air-cooled Porsche with this OE Match Front Engine Oil Cooler, commonly
known as the Snake Type or Trombone Oil Cooler.
Designed as a direct replacement for the original factory oil cooler fitted to
Porsche 911 models from 1970-1973, this OE-quality component restores
efficient engine oil cooling while preserving the originality of your vehicle.
Fits:
- Porsche 911 1965-1968 2.0L / 912 SWB (F)
- Porsche 911 1968-1973 2.2L / 2.4L / 2.7L RS LWB (F)

Unlike later finned oil coolers, the trombone oil cooler uses a continuous loop of oil pipe mounted in the front wheel arch. As airflow passes over the curved tube, excess heat is dissipated from the engine oil before it returns to the engine. Its distinctive looped design earned it the nickname "Trombone Oil Cooler", and it remains an iconic feature of early long-wheelbase Porsche 911 models.
Manufactured to OE specifications, this replacement oil cooler offers excellent fitment, corrosion resistance and long-term durability, making it ideal for restorations, maintenance or replacing damaged original units.
What Does the Oil Cooler Do?
Engine oil performs two vital functions in an air-cooled Porsche: lubricating internal engine components and carrying away excess heat.
The front-mounted Snake Type oil cooler helps to:
- Reduce engine oil temperature.
- Improve lubrication under demanding driving conditions.
- Protect internal engine components from excessive heat.
- Maintain stable oil viscosity.
- Increase engine reliability and longevity.
- Support consistent engine performance during warm weather and spirited driving.
Although simple in design, the trombone cooler provides a significant improvement in oil temperature control compared to engines without a front-mounted oil cooler.
Why Do Oil Coolers Need Replacing?
After decades of service, oil coolers can become damaged or
less effective due to:
- External corrosion.
- Stone impacts and road debris.
- Internal contamination.
- Oil leaks caused by corrosion or physical damage.
- Accident damage.
- Previous poor repairs or deformation of the cooling loop.
Replacing a damaged oil cooler helps maintain correct oil temperatures while preventing potentially expensive engine damage caused by oil loss.
Symptoms of a Failing Oil Cooler
Common warning signs include:
- Visible oil leaks around the cooler.
- Rising engine oil temperatures.
- Oil residue around the front wheel arch.
- Corroded or damaged cooling tube.
- Reduced cooling efficiency.
- Oil pressure concerns caused by oil loss.
- Physical damage from road debris.
If any oil leakage is present, the cooling system should be inspected immediately.
When Should the Trombone Oil Cooler Be Replaced?
Replacement is recommended when:
- Oil leaks develop.
- Corrosion weakens the cooling tube.
- Accident damage has occurred.
- Restoring a classic Porsche to factory specification.
- Replacing damaged front oil lines.
- Carrying out a complete oil cooling system overhaul.
Replacing ageing cooling components helps maintain reliable engine temperature control and protects your investment.

The OE Match Radiator Engine Oil Cooler with Screw Socket is a premium-quality replacement engine oil cooler designed to regulate engine oil temperature on compatible Porsche models. Manufactured to OE specifications for fit, cooling efficiency and durability, this oil cooler helps maintain optimum oil temperatures by dissipating excess heat, ensuring consistent lubrication and protecting critical engine components under all driving conditions.
Fits:
- Porsche 911 1965-1968 2.0L / 912 SWB (F)
- Porsche 911 1968-1973 2.2L / 2.4L / 2.7L RS LWB (F)

Manufactured from high-quality aluminium with precision-engineered cooling fins and an integrated screw socket connection, the oil cooler is designed to provide excellent heat transfer while withstanding high oil pressures, thermal cycling and engine vibration. Its direct OE-style fitment ensures straightforward installation and reliable, leak-free operation, making it ideal for both routine maintenance and engine restoration projects.
What This Product Does:
- Dissipates heat from the engine oil.
- Maintains optimum engine oil operating temperature.
- Helps preserve correct oil viscosity.
- Protects internal engine components from excessive heat.
- Supports efficient engine lubrication.
- Improves engine reliability during normal and high-performance driving.
- Provides secure oil connections via the integrated screw socket.
- Forms an essential part of the engine lubrication and cooling system.
Symptoms Of Wear Or Failure:
- Engine oil leaks around the cooler or connections.
- Visible corrosion or physical damage to the cooler.
- Elevated engine oil temperatures.
- Engine overheating under load.
- Oil residue around the oil cooler assembly.
- Reduced engine performance due to excessive oil temperatures.
- Low engine oil level caused by leaks.
- Contaminated cooling fins restricting airflow.
- Oil pressure fluctuations caused by oil loss.
- Premature engine wear due to inadequate oil cooling.
Why Replacement Matters:
- The engine oil cooler is continuously exposed to high oil pressures, extreme temperatures, road debris and environmental contaminants. Over time, corrosion, blocked cooling fins or internal deterioration can reduce its cooling efficiency or result in oil leaks.
- A leaking or inefficient oil cooler can cause engine oil temperatures to rise, reducing lubrication performance and increasing wear on bearings, pistons, camshafts and other critical engine components. Continued operation with overheated or leaking engine oil can lead to accelerated engine wear and potentially costly mechanical damage.
- Replacing a worn or damaged engine oil cooler restores efficient oil cooling and reliable lubrication performance. The OE Match replacement provides factory-style fitment, high-quality aluminium construction, integrated screw socket connections and long-lasting durability, helping maintain engine protection, performance and reliability throughout the life of your Porsche.
