| Oil Cooler |
 |
Oil coolers are necessary to keep the temperature of the oil, needed for the functioning of the engine and its subsystems, under control. In fact there are oil exchangers for the oil of the engine main lubrication circuit, of the automatic transmission and the powersteering. Too high temperatures lead to a rapid degradation of the oil's lubrication characteristics with the risk of damaging mechanical parts. They may be designed to exchange heat between oil and air rather than oil and the coolant in the engine cooling circuit. The latter involves simplified oil circuits and low costs if compared to the oil-air solutions which offer higher performances and do not imply an additional thermal load for the radiator.
