Komatsu Radiator 21N-03-53111 – Genuine Cooling System Protection for PC1250-11 Excavators
The Komatsu Radiator (Part No. 21N-03-53111) is a critical, high-performance cooling component engineered specifically for the Komatsu PC1250-11 hydraulic excavator. As an integral part of the machine's thermal management system, this radiator ensures optimal engine temperatures even under the most extreme working conditions — heavy digging, continuous cycling, and high ambient temperatures typical of mining and large-scale earthmoving operations.
Manufactured to Komatsu's rigorous OEM specifications, this genuine-grade radiator delivers superior heat dissipation through its advanced core design. It works in conjunction with the PC1250-11's hydraulic fan drive system — which can be reversed from the cab for easy debris cleaning — to maintain consistent cooling efficiency and protect the powerful SAA6D170E-7 engine from overheating .
Choosing the genuine 21N-03-53111 radiator means investing in long-term reliability, reduced downtime, and the peace of mind that comes with using original Komatsu components. Designed to work seamlessly with Komatsu's recommended Non-Amine Engine Coolant (AF-NAC), this radiator provides excellent anti-corrosion and anti-freeze protection for up to 2 years or 4,000 hours of operation .
Key Selling Points :
✔ OEM Genuine Quality – Precision-engineered to Komatsu's exact specifications for a perfect fit and reliable performance in the PC1250-11.
