Product Information
Both the 964 and 993 ran hotter than earlier air-cooled 911s for a variety of reasons. Increased performance output, new emissions regulations, and limited space in the engine bay were all contributing factors. Porsche was definitely stretching the limits of air/oil cooling. Especially given the cooling technology and design of that day and age.
This high performance offering from CSF for the 964 and 993 is a true OEM+ upgrade, engineered with modern cooling technology. Its advanced core offers multiple advantages over the original tube and fin design.

An engine oil cooler is a heat exchanger designed to assist in maintaining stable and adequate oil temperatures to prevent oil breakdown under heavy load conditions. It works by circulating engine oil through a series of small heat conductive passages that are exposed to either airflow (air to oil type) or coolant (water to oil type), depending on the design. Good quality synthetic oil begins to lose protection and lubrication properties generally around 300F and breaks down completely before 500F. In situations where the oil may be approaching this temperature range, it's crucial to bring it back down to standard operating levels.
In an air-to-oil cooler, good airflow is required to ensure the heat is effectively vented. In water-to-oil coolers, engine coolant flowing to the radiator is used to cool the oil. This does not require any additional ducting or fans, which makes this design increasingly popular with carmakers due to additional benefits in engine bay packaging.
Engine oil coolers typically have a thermostat built into the oil cooler circuit that opens and closes depending on the temperature of the oil, to avoid overcooling when temperatures are in a good range.
Engine oil coolers can fail for a few reasons, most commonly due to leaks, blockages, or physical damage. For air-to-oil coolers, the most common failure mode is physical damage caused by road debris or age/rust. Water-to-oil coolers have a different issue. Internal failure can cause coolant to mix with the oil, which will cause a milkshake-like consistency in the oil similar to a blown head gasket.
Engine Oil Cooler Failure Symptoms- External Leaks: Air-to-oil coolers are exposed to difficult road conditions and can be vulnerable to damage from rocks or other road debris.
- Age/Corrosion/Rust: Due to the harsh exposure to the elements, engine oil cooler lines are susceptible to increased levels of corrosion or rust, especially at the fittings. If bad enough, the fittings can become corroded enough to leak, or at minimum lose the ability to service the oil cooler
- Internal failure: Water-to-oil coolers are susceptible to internal failure, which can result in the engine coolant mixing with the engine oil. If gone unnoticed, this can result in engine failure, so it is important to regularly observe coolant or oil quality to ensure the oil cooler is in good shape, especially in older, higher-milage vehicles. Mixing water and oil will result in a “milkshake” style appearance in the fluid.
- Exterior seal leaks: When replacing a water-to-oil style cooler, it is critical to also replace the seals to avoid oil or coolant leaks upon reassembly. These seals can leak either oil or coolant depending on age, mileage, and heat cycling.
