Komatsu 207-03-41171 Hydraulic Oil Cooler Assembly

The 207-03-41171 hydraulic oil cooler is engineered to meet OEM specifications for Komatsu PC360-10 and PC390-10 series hydraulic excavators. It functions as a critical heat exchanger within the hydraulic circuit, maintaining optimal fluid viscosity and preventing thermal degradation of hydraulic components under continuous heavy-duty cycles. Constructed with aluminum core and tank assemblies, this unit replaces the OEM three-piece core design. It features precision-brazed plate-fin architecture for high heat rejection efficiency and resistance to pressure spikes. The cooler interfaces directly with existing hydraulic plumbing and mounting points, ensuring precise fitment without modification. Verified interchange includes Active Radiator MPN 271409.
