Detailed Product Description

The CSF 3571 radiator is engineered with a 1 Row Plastic Tank Aluminum Core, combining lightweight aluminum for the core with durable plastic tanks to balance performance and cost. The radiator’s core measures 7/8 inch thick, 25 7/8 inches wide, and 16 11/16 inches long, providing sufficient surface area for effective cooling. Its down flow design ensures coolant flows vertically through the core, which is common in many Cadillac CTS cooling systems.

This radiator also integrates a high-efficiency plate type oil cooler measuring 14 3/4 inches, enhancing engine oil temperature regulation. The OEM style plastic tanks are designed for durability and include quick-connect fittings for the oil cooler, simplifying installation and maintenance.
