Mounted directly on the engine, the oil cooler transfers heat away from the engine oil, helping to maintain stable operating temperatures under normal and demanding driving conditions. Effective oil temperature management is essential for preserving oil viscosity, reducing engine wear and supporting long-term engine reliability.
What This Product Does:
- Reduces engine oil temperatures during operation.
- Helps maintain correct oil viscosity and lubrication performance.
- Transfers excess heat away from the engine oil.
- Supports efficient engine cooling and thermal management.
- Protects internal engine components from excessive heat.
- Helps maintain stable oil pressure under varying operating conditions.
- Contributes to engine longevity, reliability and performance.
Symptoms Of Wear Or Failure:
- Visible engine oil leaks around the oil cooler assembly.
- Oil residue on surrounding engine components.
- Rising engine oil temperatures.
- Engine overheating under load.
- Reduced oil pressure.
- Oil contamination or coolant contamination in certain failure scenarios.
- Oil warning light illumination.
- Loss of engine performance during prolonged operation.
- Corrosion, cracking or physical damage to the cooler core.
- Unexplained engine oil loss.
Why Replacement Matters:
- Engine oil coolers operate in demanding conditions and are continuously exposed to temperature fluctuations, oil pressure, vibration and environmental contaminants. Over time, the cooler core can become corroded, blocked or develop leaks that reduce cooling efficiency and compromise lubrication system performance.
- A failing oil cooler can allow engine oil temperatures to rise beyond optimal levels, causing reduced lubrication effectiveness and increased wear on critical engine components. Oil leaks can also lead to reduced oil levels and pressure, potentially resulting in severe engine damage if left unresolved.
- Replacing a worn or damaged oil cooler restores proper oil temperature control, maintains lubrication efficiency and helps protect the engine from excessive heat-related wear. An OE Match replacement provides factory-style fitment, efficient heat dissipation and long-term durability, ensuring reliable operation of your Porsche's lubrication and cooling systems.

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.
Fits:
- Porsche 911 1974-1977 2.7L / 1976-77 3.0 Carrera
- Porsche 911 1978-1983 3.0L / SC

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.

Front Radiator Oil Cooler
Mounted at the front of the vehicle's external oil cooling
circuit, the cooler uses passing airflow to remove excess heat from the
circulating engine oil. This is particularly important on air-cooled Porsche
911 engines, where engine oil plays a major role in both lubrication and
temperature control.

Diagram Ref No 13
What Does the Front Oil Cooler Do?
Hot engine oil is circulated from the rear-mounted engine through the external oil lines to the front cooler. Air passing through the cooler removes heat from the oil before it returns through the lubrication system.
Maintaining a suitable oil temperature helps preserve oil viscosity and provides reliable lubrication for bearings, camshafts and other heavily loaded engine components.
Why Do Oil Coolers Fail?
After decades of use, an original Porsche 911 oil cooler can
deteriorate through:
- External corrosion
- Oil leaks
- Damaged or corroded fittings
- Stone and road debris damage
- Bent or damaged cooling fins
- Internal contamination
- Previous accident damage
- Blocked airflow through accumulated dirt and debris
Oil leakage or restricted cooling efficiency should be investigated promptly, particularly on an air-cooled engine.
When Should It Be Replaced?
Replacement should be considered if the cooler is leaking, physically damaged, badly corroded or no longer providing effective heat transfer.
Unusually high engine oil temperatures should not automatically be blamed on the cooler. The external thermostat, oil pipes, airflow, oil level and associated cooling components should also be checked before replacement.
Important Installation Information
The cooler does not include the temperature sensor or blanking plug and washer. These are available separately and should be selected according to the vehicle's installation.
When replacing the cooler, also inspect:
- External oil pipes and hoses
- Oil line connections
- Oil thermostat operation
- Cooler mounting rubbers and brackets
- Temperature sensor where fitted
- Airflow around the cooler
- Evidence of contamination within the oil circuit
