Core Product Features
OEM-Level Compatibility & Fitment
Manufactured to the exact specifications of OEM part number 4448338, this radiator offers a direct bolt-on replacement for Hitachi ZAXIS excavators. The precision-machined ports, mounting points, and dimensions guarantee a perfect fit, enabling quick, hassle-free installation that minimizes equipment downtime during maintenance or repairs.
Enhanced Thermal Efficiency
The large, high-density core design maximizes surface area, allowing for rapid heat dissipation even under continuous heavy loads and high ambient temperatures. This prevents engine overheating, which is a leading cause of reduced performance and premature engine wear in excavators.
Heavy-Duty Durability
Built to withstand the harsh conditions of construction sites, the radiator features a reinforced structure resistant to vibration, thermal stress, and corrosion from dust, debris, and coolant chemicals. This ensures long-term reliability, even in the most demanding operating environments.
Leak-Proof & Pressure-Resistant
The high-quality construction and precision-sealed header tanks prevent leaks and maintain consistent coolant pressure, protecting the engine from damage caused by overheating or coolant loss.
Applications & Operational Benefits
This radiator is specifically designed for Hitachi ZAX200, ZAX225US, ZAX230, and ZAX240 excavators, which are widely used in construction, mining, and material handling operations. By maintaining optimal engine temperatures, it helps to:
Preserve engine power and torque output during prolonged heavy-duty use.
Reduce the risk of costly engine damage caused by overheating, such as head gasket failure or warped components.
Improve fuel efficiency by ensuring the engine operates at its most efficient temperature range.
Extend the service life of critical engine components, reducing maintenance costs and downtime.
Ideal for fleet operators, maintenance teams, and repair shops, the SFENG-100 radiator offers a reliable, cost-effective replacement solution that delivers OEM-level performance at a competitive price.
