OE Match engine-mounted oil cooler. This heat exchanger forms part of the engine oil temperature-control system.
Fits
Porsche 997 C2S / C4S 3.8L 2005-08
Applications cover the 997 (911) MK1 Carrera 2S and Carrera 4S with the 3.8L engine, including Coupé and Cabriolet versions. The supplied diagram identifies engine type M97.01 for this component.
Check fitment for your specific vehicle (model, year, engine) before ordering.
Diagram: item 18
What This Product Does
The heat exchanger helps regulate engine oil temperature by transferring heat away from the lubricant. Oil temperature management supports the lubrication system as engine load and operating conditions change. This component mounts on the engine; it is not a front-mounted cooling radiator or a transmission oil cooler.
Functions
- Transfers excess heat away from engine oil.
- Helps regulate lubricant operating temperature.
- Supports the engine’s oil cooling circuit.
Technical Details
- Brand: OE Match.
- Component: engine-mounted oil cooler / heat exchanger.
- Product reference retained from the supplied record: 99710702502.
- Internal diagram part reference: 99710702500.
- Engine application identified in the diagram: M97.01, 3.8L.
- Supplied application years: 2005–2008.
Symptoms of Fault
- Oil seepage or dampness near the cooler and its seals.
- Oil temperatures that remain unusually high.
- Fluid loss or staining around adjoining connections.
- Possible oil and coolant contamination where an internal leak allows the circuits to communicate.
These signs do not establish that the cooler itself has failed. Inspect the seals, connections and surrounding components before deciding which parts require renewal.
Why Replacement Matters
A leaking or obstructed cooler can compromise oil temperature control. Replacing a confirmed faulty unit addresses the damaged component, while checking adjoining seals and connections helps identify other sources of leakage. OE Match’s Porsche-focused replacement programme uses application and original-reference checks when assessing component suitability.
FAQs
Does high oil temperature always mean the cooler needs replacing?
No. Oil level, cooling-system condition and operating load also require investigation.
Should the surrounding seals be checked?
Yes. Leakage may originate at a seal or connection rather than within the exchanger.
Will flushing repair an internally leaking cooler?
No. Cleaning removes contamination but does not repair the underlying fault. Establish the cause before replacing components.

Diagram Ref No 30
The vent hose forms part of the engine oil cooler system, providing the necessary connection between associated components and helping the system operate correctly. Positioned within the engine compartment, the hose is continually exposed to heat, vibration and temperature cycling, which can cause the original material to harden and deteriorate with age.
Replacing a brittle, cracked or damaged hose helps maintain a secure system and reduces the risk of leaks or further deterioration.
What Does an Engine Oil Cooler Vent Hose Do?
The oil cooler vent hose forms part of the connections associated with the engine oil cooling system. Its purpose is to maintain the correct routing and ventilation between the relevant components while providing a flexible connection capable of accommodating engine movement and vibration.
A serviceable hose helps provide:
Correct operation of the associated oil cooler system Secure connection between components Resistance to engine movement and vibration Reliable sealing and system integrity
Why Do Oil Cooler Vent Hoses Fail?
Engine compartment hoses naturally deteriorate with age. Continuous exposure to heat causes the material to gradually lose flexibility, while vibration and repeated heating and cooling cycles can accelerate deterioration.
Common causes include:
- Age and high mileage
- Constant engine heat
- Repeated heat cycles
- Rubber becoming hard or brittle
- Cracking around connection points
- Oil and chemical contamination
- Engine vibration
- Previous removal or incorrect installation
Older hoses may appear serviceable externally but can crack when disturbed during maintenance.
When Should the Hose Be Replaced?
Replacement should be considered if:
- Cracks or splits are visible
- The hose has become hard or brittle
- Connections are loose or deteriorated
- Leakage or residue is visible around the hose
- The hose is damaged during removal
- The oil cooler system is being serviced
- The engine is undergoing major maintenance or refurbishment
Preventative replacement is particularly worthwhile when surrounding components have already been removed, avoiding additional labour should an ageing hose fail later.
Porsche Engine Oil Cooler Hoses & Cooling System Components
The engine oil cooling system plays an important role in maintaining stable operating temperatures and protecting internal engine components. Hoses and connections within the system are therefore important service items, particularly as Porsche vehicles become older.
Heat, vibration and age can cause original hoses to become brittle, cracked or unreliable. Inspecting and replacing deteriorated hoses during oil cooler or engine maintenance helps prevent leaks and provides greater confidence in the integrity of the system.
When replacing an oil cooler vent hose, it is also worthwhile inspecting nearby hoses, connectors, seals and fittings for similar age-related deterioration.
