Mitsubishi S6R2-PTA
The radiator is a custom-engineered cooling component specifically designed for the Mitsubishi S6R2-PTA diesel engine, a widely used power unit in industrial and heavy-duty applications. Its core function is to maintain the engine's optimal operating temperature by efficiently dissipating excess heat generated during combustion and mechanical operation, thereby protecting critical engine parts from overheating damage.
Features
Engine Compatibility: Tailored to match the S6R2-PTA engine's coolant flow rate, inlet/outlet dimensions, and mounting points, ensuring seamless installation without modifications.
Durable Construction: Adopts corrosion-resistant materials to withstand harsh operating environments, including high humidity, dust, and occasional coolant chemistry variations.
Enhanced Performance: Features optimized fin density and airflow design to maximize heat dissipation efficiency, even in environments with high ambient temperatures or limited ventilation.

Maintance and Service
Armor-Like Transit Protection: We use reinforced wooden crates plus advanced moisture barriers. This packaging resists corrosion and impact, ensuring your radiator arrives perfect.
Zero-Leak Guarantee: Beyond basic checks, every radiator gets rigorous pressure testing (mimicking real-world stress). This ensures no leak failures—you get a flawless product.
A 2-Year Pledge of Reliability: Unlike most 1-year competitor warranties, we offer 2 years. This shows our confidence in quality and gives you long-term peace of mind.
How We Produce
Every SINRUI radiator is made in our state-of-the-art workshop, with meticulous oversight covering every stage—from copper tube formation to final frame assembly. This end-to-end control ensures strict compliance with international standards.
Our ISO 9001-certified processes require comprehensive testing (leak, pressure, thermal performance) for every unit. The result is a product that guarantees consistent quality, long-term durability, and top-tier heat dissipation efficiency.
