Oil Coolers
Engine and transmission oil cooling
OE Matching Quality
Oil applied for lubrication plays a significant cooling role. The oil cooler receives the lubricant’s heat and exchanges it with the ambient air or the radiator coolant. It is typically the automatic gearbox oil that needs a dedicated oil cooler. Vehicles, driving with engine oil that is cooled by a separate exchanger, is a common sight. Especially in high-performing or downsized engine vehicles, a dedicated oil cooler is an important part of the system.
In some vehicle models, the oil cooler is built into the radiator water tank. Here, the coolant plays a supportive role to the heat exchange process. In modern vehicles, an automatic gearbox oil cooler is often designed as a stand-alone unit, mounted separately in the engine compartment or on the engine block.
Reliability & Performance
The oil cooler development process includes an in-house test series, where the oil cooler is pressure-impulse tested with 100,000 impulses at a pressure of up to 10.0 bar.

Improved turbulator design, ensuring more precise brazing process, thus supreme durability and stress resistance of the component.
Thermal expansion tested to perform during fluctuations of temperatures, ranging from 10 to 90 °C.
Technical Details
Be aware of regular oil change and proper oil filtration. Low-quality or contaminated oil can clog the thin channels of the oil cooler, limiting the inside flow and performance.
A leaking or non-performing oil cooler is one of the most common causes for automatic gearbox break down. The oil is crucial for the gearbox’s operation as it lubricates, cleans and conditions its seals.
In the case of leakages, the lack of oil will cause the engine to overheat and shut down.
Exposure to high stress, like high temperatures or high mileages can shorten the oil cooler’s lifespan significantly.
