Required Quantity: Two gaskets are required for the heat exchanger assembly

This gasket forms part of the engine oil cooler, also described as the heat exchanger, and its connection to the oil filter console or oil-conducting housing. The cooler manages heat in the lubrication system, while the gasket seals the joint where the components meet. Its sealing action depends on correct seating and the condition of the adjoining surfaces. It is relevant to a localised cooler-joint repair as well as work that requires the heat exchanger to be removed.

What Does This Part Do?

• Seals the cooler joint: Forms a sealing interface between the heat exchanger and its adjoining housing.
• Helps contain fluid: Limits leakage through the connection when correctly installed against sound mating surfaces.
• Completes the sealing assembly: Works with the housing, cooler and fixings to maintain the joint during engine operation.
  
  

Why Replace This Part?

A gasket that has deteriorated, become distorted or suffered damage during removal may no longer seal its joint correctly. Replacement is appropriate when inspection confirms leakage from this connection or shows that the existing gasket cannot be refitted in serviceable condition. Wetness nearby should be traced carefully, because fluid from another seal or housing can collect around the cooler.

During dismantling, inspect the cooler, housing, sealing recesses and fixings as well as the gasket. A new seal cannot compensate for a cracked housing, damaged mating face or incorrectly assembled joint. OE Match supplies replacement parts focused on Porsche applications; selecting the correct gasket version remains important to the repair.

When to Replace This Part?

• Confirmed joint leakage: Fresh seepage returns at the heat exchanger connection after the area has been cleaned and inspected.
• Visible damage: The removed gasket has cuts, splits, distortion or damaged sealing edges.
• Poor seating: The gasket no longer sits correctly in its intended position.
• Removal damage: Dismantling has damaged the gasket or left it unsuitable for reuse under the applicable workshop procedure.
• Repeated leakage: Inspect the mating surfaces and complete assembly before fitting another gasket.
  
  

Where Is This Part Fitted?

Location: At the engine-mounted oil heat exchanger connection within the oil filter console or oil-conducting housing assembly. Access and the surrounding components differ between the listed engines.

Technical Details

• Component type: Engine oil cooler / heat exchanger gasket.
• Cayenne engine context: M48.00 / M48.50 in the 955 oil filter console and heat exchanger assembly.
  
  FAQs

• Does leakage around the cooler mean the cooler needs replacing?
  Not necessarily. Inspect the gasket joint, adjoining housing and nearby seals to establish the source before choosing replacement parts.
• Will this gasket resolve high oil temperature?
  High oil temperature alone does not identify a gasket fault. Check fluid levels and investigate the cooling and lubrication systems rather than assuming this seal is responsible.
• What should be checked when fitting it?
  Check the mating surfaces, sealing recesses and fixings, and follow the engine-specific installation procedure. Investigate any housing damage before reassembly.

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.

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
