Detailed Product Description

This radiator features a single-row core constructed from PA material with plastic tanks, providing a balance of durability and weight savings. The core measures 16 3/4 inches in height, 26 5/16 inches in width, and 1 1/4 inches in thickness, optimized for efficient heat dissipation. Both inlet and outlet headers measure 27 3/8 inches in length and 2 1/2 inches in width, with inlet and outlet diameters of 1 7/16 inches, ensuring compatibility with the specified Mercedes-Benz cooling systems.

Equipped with a concentric transmission oil cooler, this radiator supports transmission fluid cooling with fittings spaced 13 inches apart and a cooler diameter of 1 1/2 inches. The design excludes an engine oil cooler, focusing on core engine and transmission cooling needs. The downflow configuration promotes effective coolant flow through the core, maintaining stable engine temperatures under various driving conditions.
