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.

Designed as a direct OE-style replacement, it is ideal when replacing the oil cooler, rebuilding an engine or carrying out preventative maintenance on early engine cases.
What This Product Does:
- Provides the components required to install the engine oil cooler correctly.
- Creates secure, leak-free seals between the oil cooler and engine case.
- Maintains correct engine oil flow through the oil cooler.
- Supports efficient engine oil cooling.
- Helps prevent oil pressure loss caused by leaking seals.
- Restores factory oil cooler installation standards.
- Ensures compatibility with early engine cases using 6mm x 8mm studs.
- Forms an essential part of the engine lubrication system.
Symptoms Of Wear Or Failure:
- Engine oil leaking around the oil cooler.
- Oil residue on the engine case or cooling fins.
- Low engine oil level due to external leaks.
- Reduced oil pressure caused by sealing failure.
- Oil contamination around the oil cooler mounting area.
- Hardened, cracked or compressed seals.
- Difficulty achieving a leak-free oil cooler installation.
- Oil dripping beneath the vehicle.
- Increased engine operating temperatures if oil flow is affected.
- Premature wear of lubrication system components.
Why Replacement Matters:
- Oil cooler seals and installation components are continually exposed to hot engine oil, pressure fluctuations and repeated thermal cycling. Over time, seals naturally harden, compress or lose their elasticity, reducing their ability to maintain an effective seal between the oil cooler and engine case.
- A leaking oil cooler installation can result in oil loss, reduced lubrication performance and contamination of the engine bay. If left unresolved, oil pressure may be compromised, increasing the risk of accelerated engine wear or serious internal damage. During oil cooler replacement or engine rebuilding, installing new seals and hardware is essential for reliable, long-term performance.
- Replacing the original installation components with the OE Match Oil Cooler Installation Kit ensures the oil cooler is mounted securely and sealed correctly. Manufactured to OE standards using premium-quality heat- and oil-resistant materials, this kit provides factory-style fitment, dependable sealing performance and long-lasting durability, helping maintain efficient engine cooling, reliable lubrication and the performance expected from your Porsche.
