About the 1 Row Plastic Tank Aluminum Core Product Line

The CSF 1 Row Plastic Tank Aluminum Core line combines lightweight aluminum cores with OEM-style plastic tanks to balance durability and cost-effectiveness. This product line is engineered to meet factory specifications, ensuring proper fitment and performance for vehicles like the Hyundai Elantra.

Detailed Product Description

The CSF 3340 radiator features a 5/8 inch thick aluminum core that measures 23 5/8 inches in length and 17 5/8 inches in width, providing a solid surface area for heat exchange. The plastic tanks are molded to OEM specifications, ensuring a precise fit and reliable sealing. The cross flow configuration enhances coolant flow from the inlet on the right side to the outlet on the left, both with 1 5/16 inch diameters.
