Abstract

The invention relates to a cooling system for an internal combustion engine on a vehicle, preferably for an agricultural or industrial commercial vehicle. The cooling system includes a high temperature circuit and a low-temperature circuit. The high temperature circuit cools the internal combustion engine and includes at least a first cooler. The low temperature circuit cools a charge air cooler and, optionally, an oil cooler and includes at least one second cooler. The charge air cooler has at least two parts or stages. In the direction of flow of coolant in the low temperature circuit, the second cooler is connected downstream of a first part of the charge air cooler, the oil cooler and a second part of the charge air cooler. Alternatively or additionally, a further cooling circuit cools the charge air cooler and includes at least one cooler.
