Built for OE-Style Cooling Performance

This OSC radiator is engineered to match original equipment form and function while addressing common failure points found in high-mileage cooling systems. The unit uses premium-grade tubes, fins, headers, and tanks, with cadmium-plated tubes inside and out to help resist premature failure. Each radiator is pressure tested during production, and the transmission and engine oil cooler circuits are checked before assembly and again after final assembly.

Part number 1552 also follows OE cooler design where originally equipped, including the concentric transmission oil cooler. For shoppers searching for a radiator for Dodge Ram 1500, Ram 2500, or Ram 3500 models, this unit provides a direct replacement path without changing the original fit or appearance.

Common Problems This Radiator Helps Address

• Overheating caused by a leaking or restricted radiator core
• Transmission temperature issues related to a failing internal cooler
• Coolant loss from cracked tanks or worn sealing surfaces
• Reduced cooling efficiency in high-mileage Dodge Ram trucks
• Fitment problems from non-OE-style replacement radiators

Installation Notes and Tips

Verify core dimensions, inlet and outlet sizes, and cooler configuration before installation. This radiator is designed as a drop-in replacement for the listed Dodge Ram and Ramcharger applications, and the factory-style layout supports straightforward installation. Confirm that the transmission cooler line connections match the vehicle before final assembly.

Part number 1552 includes the necessary fittings or hardware specified by the manufacturer. Use clean coolant, inspect hoses and clamps, and pressure test the system after installation to confirm proper sealing and circulation.

Quality Assurance

OSC builds this radiator to OES standards and tests each unit during production for cooling-system integrity. The design includes engineering updates aimed at improving durability and service life, including enhanced fin density and cooler capacity where needed for higher-heat applications.
