Reason for fundamental upgrade and modification: Old defect: The radiator in older models was made entirely of plastic (including the front water channel), which led to its cracking, breaking, and constant leakage of radiator water due to high engine heat and water pressure. Upgraded modification: The entire front part (water inlets and outlets and thermostat valve channel) has been replaced with a wide strip made of hard, rust-resistant, and heat-resistant aluminum, while the rear body of the radiator remains made of reinforced plastic to reduce weight and preserve the coolness of the air entering the engine. 📋 Technical specifications of the product: Material: An advanced blend combining heavy-duty aluminum (for parts exposed to coolant pressure) and reinforced composite plastic (for air intake channels to prevent heat soak).
