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

- Porsche 911 1978-1989 3.3L Turbo (930)
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.
Why Choose an OE Match Oil Cooler?
Our OE Match Snake Type Oil Cooler has been manufactured to faithfully reproduce the original Porsche component.
Benefits include:
- Authentic Snake Type (Trombone) configuration.
- OE-quality construction and fitment.
- Precision-formed cooling loop.
- Excellent oil flow characteristics.
- Corrosion-resistant finish.
- Straightforward installation using factory mounting points.
- Perfect for restoration and maintenance projects.

Diagram ref no 8.
The engine oil cooler helps reduce engine oil temperature by allowing heat from the oil to transfer through the cooler core. Correct oil cooling is essential on air-cooled Porsche engines, as the oil plays an important role in lubrication, heat control, and long-term engine reliability.
Functions
• Replaces the engine compartment oil cooler
• Helps regulate engine oil temperature
• Supports correct lubrication and cooling performance
• Assists in protecting the engine from excessive oil temperatures
• Helps maintain stable operation during normal and demanding driving
• Replaces leaking, blocked, corroded, or damaged original oil coolers
• OE Match replacement for engine oil cooling system repair.
Why Replace This Part?
Engine oil coolers can become blocked, corroded, damaged, or leak with age, heat cycling, vibration, and long-term oil exposure. A faulty oil cooler can cause oil leaks, reduced cooling efficiency, higher engine temperatures, contaminated cooling fins, or poor lubrication performance. Replacing the oil cooler helps restore effective oil temperature control and supports reliable engine operation.
When to Replace This Part
• The oil cooler is leaking engine oil
• Oil residue is visible around the cooler or engine compartment area
• Engine oil temperatures are higher than normal
• The cooler core is blocked, corroded, or damaged
• The engine is being rebuilt or resealed
• Oil cooling system components are being serviced
• The vehicle is undergoing Porsche 911 engine restoration or preventative maintenance

OEMatch Oil Radiators / Heat Exchangers — Durability, Sealing, Performance
Oil radiators and heat exchangers control oil temperature in Porsche engines and transmissions, supporting lubrication, consistent viscosity and component life under varied driving conditions. Many owners search for genuine or OEM oil radiators; OEMatch offers compatible replacements made to original-spec dimensions and tolerances for Porsche models.
Available Types
- Engine oil coolers for sump or external mounting
- Transmission and gearbox oil heat exchangers
- Auxiliary and remote oil radiators for additional cooling circuits
Understanding OEMatch Oil Radiators / Heat Exchangers
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original oil radiators and heat exchangers. OE (Original Equipment) refers to parts matching original specifications for the oil radiators and heat exchangers and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM oil radiators and heat exchangers engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models. OEMatch provides a wide selection of Porsche-specific items, with thousands of listed part numbers and extensive OE cross-references catalogued; product lines are continually developed and subject to quality control to address cooling-system needs across Porsche generations.
Benefits Include
- Restored oil temperature control to protect lubrication and maintain consistent viscosity
- Reduced risk of overheating and oil contamination between circuits
- Improved serviceability and longer component life for engine and transmission assemblies
Why Oil Radiators / Heat Exchangers Wear and Fail
- Corrosion or internal blockage from degraded fluids or debris
- Physical damage from road debris or impacts to fins and housings
- Seal, gasket or joint failure leading to external leaks or cross-contamination
The Importance of Replacing with OEMatch Oil Radiators / Heat Exchangers
Replacing a faulty oil radiator or heat exchanger restores cooling efficiency and helps prevent oil breakdown, overheating and consequential engine or transmission damage. Specified replacements support correct service procedures for Porsche models and help maintain lubrication performance, pressure stability and long-term component reliability.
Advantages
- Direct-fit replacements engineered to match original dimensions and tolerances
- Made to original-spec dimensions for consistent sealing and durability
- Fits original mounting points and clearances to simplify installation
Support & Advice
These items affect safety-critical systems. Installation should be carried out by a qualified technician following model-specific procedures and torque settings. Use calibrated tools and new fasteners where specified.
