OILCOOLERKIT996.OEM
Product Information
This is a complete OE Match Engine Oil Cooler Service Kit designed to fully replace and service the engine oil cooling system on select Porsche 996 and 997 models. The kit combines an OE Match oil cooler (radiator) with a full set of gaskets, seals, O-rings, fasteners, and fittings sourced from genuine Porsche OEM parts - ensuring correct sealing, fitment, and long-lasting performance.
Fits:
Porsche 996 Carrera 3.4L / 3.6L 1998 - 2005
Porsche 997.1 Carrera 3.6L 2005 - 2008
Diagram Ref No. 18, 18, 20, 21, 30, 31 and 32.
This comprehensive service kit centers around the OE Match engine oil cooler (OE ref part no. 99610702559) - a direct-fit cooling radiator that exchanges heat between engine oil and the coolant circuit to keep oil temperatures within proper limits under all driving conditions. In addition to the cooler itself, the kit includes authentic Porsche OEM parts necessary for a proper installation and leak-free operation.
Kit Includes:
• OE Match Engine Oil Cooler - OE ref no 99610702559
• Porsche Genuine hose - 99610623053
• Porsche Genuine Seals - 99970754740 and 99970738940
• Porsche Genuine hex screw - N10546403
• Porsche Genuine hose clamps - 99951255400 and 99951265209
These genuine parts are matched with the OE Match cooler to ensure factory-level sealing and durability, removing the guesswork from sourcing the correct components for an engine oil cooler service.
The engine oil cooler and its associated seals and hardware are subject to thermal cycling, pressure variation, and long-term exposure to heat and chemicals. Over time, coolers can become corroded, clogged, or internally separated, and seals can dry out, harden, or fail. This leads to:
• Oil leaks
• Elevated oil temperatures
• Reduced lubrication efficiency
• Possible engine damage from overheating or loss of oil pressure
Replacing the entire oil cooler and related seals at the same time delivers a comprehensive refresh of the system - reducing the risk of repeat leaks, improving cooling efficiency, and helping prolong engine life.
When to replace. Install this oil cooler service kit when:
• You detect oil or coolant leaks near the oil cooler
• The vehicle has high mileage with original components
• You’re experiencing oil temperature fluctuations or overheating conditions
• You are performing a coolant system or engine refurbishment
• Internal oil cooler passages show blockage or contamination

Product Information
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

About Oil Radiators / Heat Exchangers
Oil Radiators & Heat Exchangers – Optimal Temperature Control for Porsche Performance
Oil radiators and heat exchangers are crucial components in your Porsche’s engine and transmission cooling systems. They regulate oil temperature by transferring heat away from the lubricating or hydraulic fluids, ensuring consistent performance, efficient lubrication, and long-term engine protection — even under extreme driving conditions.
At Design911, we offer a complete range of genuine and manufacturer-quality oil radiators and heat exchangers for Porsche models including 911, Boxster, Cayman, Cayenne, Macan, and Panamera. Each unit is engineered for precise fitment, efficient heat transfer, and long-lasting reliability — maintaining the high-performance standards that Porsche vehicles are known for.
What Do Oil Radiators & Heat Exchangers Do?
Oil radiators and heat exchangers serve a vital role in
temperature regulation and system protection. They:
- Dissipate
heat from engine or transmission oil to prevent overheating.
- Maintain
stable oil temperature for optimal viscosity and lubrication.
- Extend
component lifespan by preventing thermal damage.
- Support engine and gearbox efficiency under heavy load or high-speed conditions.
By controlling oil temperatures, these parts ensure consistent power delivery, reduced wear, and greater reliability — whether on the road or track.
Why Do Oil Radiators & Heat Exchangers Fail?
Despite being built to handle extreme conditions, these
components can fail over time due to wear, corrosion, or contamination. Common
causes include:
- Corrosion
or internal blockage from debris or degraded fluids.
- Physical
damage from road debris or impact.
- Oil
or coolant leaks due to cracked housings or seals.
- Reduced
heat transfer efficiency from clogged fins or internal scaling.
- Age-related deterioration of internal passages or gaskets.
Symptoms of failure include oil leaks, rising engine temperatures, reduced oil pressure, or contamination between the oil and coolant systems.
Why Replace a Faulty Oil Radiator or Heat Exchanger?
A damaged or inefficient oil radiator can cause overheating, loss of lubrication, and serious engine or transmission damage. Replacing faulty units restores cooling efficiency and ensures your Porsche continues to deliver peak performance and reliability.
Benefits of replacement include:
- Restored oil temperature control and pressure stability.
- Prevention of overheating and oil contamination.
- Improved engine and gearbox longevity.
- Manufacturer-quality construction and fitment for peace of mind.
Each radiator and heat exchanger in this range is designed to meet or exceed factory standards, using advanced materials and precision manufacturing for superior durability, corrosion resistance, and cooling performance.
