251-6149
Designed with field service in mind, the CAT 251-6149 radiator provides the CAT 777F mining truck with simplified maintenance features. Modular aluminum plate-fin assemblies and quick-release mechanisms reduce downtime and maintenance labor. The radiator’s corrosion-resistant materials extend service life and reduce the frequency of replacements, delivering significant cost savings for mining operations.
Features
The aluminum alloy base combined with surface treatment technology ensures a long service life even in harsh environments.
The one-piece core structure formed by vacuum brazing is inherently leak-resistant, providing unparalleled reliability and significantly reducing the risk of premature failure.

How We Produce
We rely on highly standardized production processes and a modular design philosophy to ensure product consistency and production scalability. By establishing unified libraries of process parameters, standard operating procedures, and quality inspection criteria, we achieve precise OEM specification matching for radiators of various brands, be it CAT, Komatsu, or Hitachi. This standardized system allows us to quickly adapt production lines and efficiently handle orders for different batch sizes and models. It guarantees OEM-level quality while enabling seamless transition from prototype trials to mass production, offering customers significant order flexibility.
