An oil cooler is a separate, smaller radiator to an engine's main radiator, which maintains an oil supply at a consistent, optimal temperature. Its purpose is to cool the oil passing through the coils, thus improving the engine and the transmission’s lifetime. They are situated in front of an engine's cooling system. Oil coolers are necessary for diesel engines (higher temperature range) and automatic gear boxes. A cooler plays an important role in the smooth running of a vehicle by dissipating heat while transporting oil away from moving parts into the oil pan.

- Causes of temperature increases
- Contact with hot parts of the engine
- Contact with the piston
- Pressure in the oil pump and the bearings
- Temperature inlet: 150 °C / Outlet temperature: 125 °C
- Hill climbing
- Temperature drop ~ -30 °C on piston
- Oil cooler causes of failures:
- Crash / gear box replacement
- Corrosion of the Core
- Stress: thermal shock, cycled pressure
- Incorrect maintenance Failures start to occur when oil cannot dissipate its collected heat fast enough and rises past this threshold. When damaged, oil loses its lubricating and cooling properties.
