Detailed Description

CSF 3660 is a radiator assembly designed around OE-style packaging for the Dodge Sprinter 2500 and Dodge Sprinter 3500. It features a plastic tank and aluminum core combination, a 1-row cross-flow layout, and a high-efficiency plate-type oil cooler section with quick-connect fittings. The radiator core measures 26 3/4 inches long by 16 inches wide, with a 1 1/4-inch core thickness, supporting factory-style cooling system service where original dimensions and connection points matter. CSF manufactures radiators to high-performance standards and validates cooling performance through lab testing and wind tunnel evaluation.

This part cross-references BBB Industries 13254 and Spectra Premium CU13254 for the same application. If you are searching for a Dodge Sprinter 2500 radiator or Dodge Sprinter 3500 radiator, CSF 3660 is a direct-fit OE-style replacement to compare against the original unit.

Common Cooling System Issues Addressed

• Cracked or leaking radiator tanks
• Restricted coolant flow from an aging core
• Overheating caused by reduced heat transfer
• Damaged oil cooler connections at the radiator
• Fitment problems from non-OE-style replacement parts

Installation Notes and Tips

Verify inlet and outlet orientation before installation: the inlet is on the left and the outlet is on the right. Confirm the vehicle uses the same cross-flow layout and quick-connect oil cooler fittings before removal of the original radiator. Transfer any reusable components from the existing cooling system as required by the vehicle configuration, and inspect hoses, clamps, and coolant condition during service. For best results, flush the cooling system if contamination or debris is present.

Quality Assurance

CSF radiators are manufactured in ISO/TSO-certified facilities and built to support consistent cooling performance across a wide range of vehicle applications. The brand has supplied radiators worldwide for decades and produces a large catalog of OE-style replacement units for major vehicle platforms.
