Importance of Oil Cooler Core 208149 The oil cooler core 208149 plays a crucial role in maintaining the optimal temperature of the engine oil. As the engine runs, it generates heat which is absorbed by the oil. However, when the oil temperature exceeds a certain level, it can cause damage to the engine components. The oil cooler core ensures that the oil is cooled down to a safe temperature by passing it through a network of small tubes while allowing air to pass over it. This process efficiently dissipates the heat, preventing damage to the engine and improving its overall durability. Therefore, the oil cooler core 208149 is an essential component in ensuring the longevity and performance of the engine.   Part Number:208149 Part Type:Oil Cooler Core Brand:Cummins Attributes LxWxH:15 x 3.5 x 3.5 inches OEM Alternative Part Number:Cummins 3021581 Compatibility:Cummins NT855 855 FFC NT855 NH/NT   208149 Picture show
