Engine oil cooler lines and hoses are critical components that circulate oil between the engine and oil cooler, maintaining optimal operating temperatures in heavy equipment, commercial trucks, and agricultural machinery. Radiator Supply House offers an extensive catalog of OEM-compatible and custom lines for leading brands including Caterpillar, John Deere, Komatsu, and more.




Engine oil cooler lines are hoses or metal tubes that carry engine oil from the engine block to the oil cooler and back. They regulate oil temperature by routing it through a cooler, preventing overheating and maintaining proper viscosity. These lines are essential in heavy equipment, commercial trucks, and agricultural machinery operating under sustained high loads.
