Maintance and Service
Protective Packaging – Reinforced wooden crates with moisture-proof linings are used for the radiator, preventing copper component corrosion and structural damage during transit.
Precision Pressure Testing – Every radiator is rigorously pressure-tested to ensure it holds perfect pressure, preventing future failures and protecting your engine.
Warranty Coverage – We back our radiator services with a robust 2-year warranty—this commitment far outperforms the industry's typical short-term guarantees (often 6–12 months). It stands as our strong promise to product durability, giving you long-term peace of mind for your investment.
How We Produce
At SINRUI, we ensure every radiator delivers both resilience and efficiency—all thanks to our end-to-end, strict oversight throughout production. From selecting raw materials to completing final welding, each unit is crafted in our advanced workshop, with no detail overlooked in the manufacturing process.
This dedication to quality is reinforced by our ISO 9001 certification—a standard that mandates every radiator pass a series of rigorous tests: leak detection, pressure validation, and thermal performance checks.
