Information
Radiator oil cooler on engine.
This engine oil cooler is a direct replacement for the original Porsche unit. It functions as a water-to-oil heat exchanger, efficiently transferring heat from the engine oil to the coolant to maintain optimal operating temperature. Built to OEM specifications, it ensures reliable cooling, consistent oil viscosity, and long-term engine protection under demanding conditions.
Fits:
Porsche 986 Boxster 2.5L / 2.7L 1994 - 2004
Porsche 987 Boxster 2.7L / 3.2L 2005 - 2008
Porsche 987C Cayman S 3.4L 2005 - 2008
Diagram Ref No 18.
Benefits:
• Maintains optimal oil temperature to reduce wear, prevent oil breakdown and engine damage
• Direct-fit replacement ensures correct mounting, connections and flow rate
• Engineered for long life and reliability even in high-stress driving environments
Over time, engine oil coolers are exposed to high thermal cycles, pressure, and contaminants that can cause internal clogging, corrosion, or coolant-to-oil leaks. A failing cooler can lead to elevated oil temperatures, reduced lubrication, and even engine damage due to oil breakdown or cross-contamination.
When to replace:
• When oil temperature readings are abnormally high or fluctuating.
• If you notice oil in the coolant or coolant in the oil (a sign of internal leakage).
• During engine rebuilds or cooling system overhauls to ensure proper performance.
• As preventive maintenance on older engines or vehicles used in track or high-load conditions.
Replacing the oil cooler restores efficient heat transfer, maintains stable operating temperatures, and ensures long-term engine reliability.
