Information
Radiator oil cooler on engine.
OE Match engine oil cooler / radiator designed to replace the original Porsche oil cooler that sits on the engine’s cooling circuit. It acts as a crucial element of the engine oil cooling system, transferring heat from the engine oil to the coolant or ambient airflow (depending on the specific engine layout) to maintain optimal oil temperature during operation.
Fits:
Porsche 996 1998 - 2005
Porsche 997.1 3.6L 2005 - 2008
Porsche 986 Boxster S 3.2L 1999 - 2004
Diagram Ref No 18.
The oil cooler regulates the temperature of engine oil as it circulates through the engine. By reducing thermal load on the oil, it helps:
• Maintain correct oil viscosity for effective lubrication
• Reduce wear on internal engine components
• Improve engine performance under load or high-temperature operation
• Prevent oil breakdown and reduce risk of overheating.
Without an effective oil cooler, engine oil can run too hot, degrading lubrication and potentially accelerating engine wear or promoting heat-related performance issues.
Function
• Heat dissipation: Transfers heat from the oil to coolant or airflow
• Oil temperature stability: Helps keep oil within operational temperature range
• Wear protection: Prevents high temperatures from accelerating oil degradation
• Performance support: Ensures stable lubrication for engine components under stress
The engine oil cooler operates in a harsh thermal environment and can suffer from corrosion, stone impact damage, leaks, or clogging over time. A compromised cooler can lead to:
• Overheated engine oil with reduced lubrication quality
• Increased engine wear and reduced component lifespan
• Poor performance under load and in hot conditions
• Higher risk of oil leaks or contamination
Replacing a worn or damaged oil cooler with a quality OE Match unit helps restore proper oil temperature control, improves overall engine reliability, and supports long-term performance.
When to replace. Replace the oil cooler when:
• There is visible oil leakage from the cooler or its connections
• You observe engine oil temperature issues or overheating warnings
• The cooler shows physical damage such as dents, corrosion, or deterioration
• You are performing a major engine coolant/oil system service
