Oil cooler tuning

The oil cooler is used to prevent the engine oil and sensitive engine parts from overheating. An additional oil cooler is required when cooling via the oil pan alone is no longer sufficient, as is the case with many modern engines. The cooled oil not only ensures optimal cooling, but also lubricates the components that are exposed to particularly high thermal loads, such as the pistons, for example.

In addition to the constant temperature of the oil, the oil cooler also ensures a constant oil pressure. The pressure is important to supply all components and gaskets of the engine with a sufficient amount of oil and thus seal it. The oil cooler therefore also has a positive effect on the service life of your engine.

Depending on the size and placement of the oil cooler, it can reduce the oil temperature by 20–30 °C. Therefore, even at high outside temperatures, it can make sense to install an additional oil cooler. This applies especially to vehicles whose stock oil coolers are generally too weak.

For performance-enhanced engines, an upgrade oil cooler is necessary to efficiently reduce the likewise increased operating temperature and thus improve performance. A stock cooler is simply not designed for the extreme thermal load. Without a powerful oil cooler, the oil pressure cannot remain constant during tuning, the oil does not reach all parts of the engine and it is permanently under-supplied. Without the upgrade oil cooler, you therefore risk not only a significant loss of performance, but also serious engine damage.

For tuned vehicles, oil cooler kits are particularly worthwhile, as they include not only the cooler but also the matching lines, connections, and a thermostat. In combination with a temperature display and an oil pressure gauge, you always have the relevant values in view and can fully concentrate on performance.

Not only in tuning is the topic of oil cooling relevant, it is also a known problem with some engines. This applies in particular to 1.6 and 2.0 TDI transporters up to model year 2013; both commercial vehicles and the popular “Bullis” are affected.

The TDI engines already have a problem with excessively high oil temperatures from the factory. If you drive them in the height of summer or your engine has increased performance, you will very quickly reach an oil temperature of 140 °C. In combination with other weaknesses of these engines, this often leads to serious problems.

We have developed an oil cooler kit specifically for 1.6 and 2.0 TDI engines that optimizes flow, keeps the oil pressure constant, increases the service life of your engine and drastically reduces the oil temperature. Installation is also designed to be simple to make it as easy as possible for you.
