PURPOSE: A vehicle cooler system is provided to significantly shorten a warm up reaching time by realizing heat exchange between oil and EGR gas during cold start. CONSTITUTION: A vehicle cooler system comprises an EGR cooler (1), an oil cooler (5), and a cooling water line (10), and an oil line (20). In the EGR cooler, EGR gas, which transmits heat to cooling water and oil depending on the engine warm up status divided into one stage or more, is emitted to the outside after passing the inside, or is emitted directly to the outside without passing the inside. In the oil cooler, oil flows to take heat from the cooling water which is discharged to the outside after circulating the inside. The cooling water line transfers the cooling water supplied from an engine cooling system depending on the engine warm up status, directly to the oil cooler without passing the EGR cooler, or to the oil cooler after passing the EGR cooler. The oil line transfers the oil supplied from an oil pump depending on the engine warm up status, directly to the oil cooler without passing the EGR cooler, or to an oil filter for filtering foreign materials in the oil discharged from the oil cooler after passing the EGR cooler.
