Thumbnail Filmstrip of 6.7 Cummins Bladerunner Street Series Radiator AFE 46-52191 Images
The AFE BladeRunner Street Series Radiator 46-52191 is the ultimate performance-grade solution to replace a leaking or inefficient factory radiator in your Dodge Ram 6.7L Cummins Diesel. When a heavy-duty diesel truck is towing or carrying heavy payloads, the factory cooling system is pushed to its absolute limits, making stock plastic-tank radiators prone to cracking under high pressure and temperature cycles. AFE engineered the BladeRunner Street Series to bridge the gap between everyday reliability and high-performance cooling. Built from aircraft-grade aluminum, this radiator completely eliminates the weak points of an OEM unit, delivering a rugged, dependable defense system that safeguards your engine from catastrophic overheating.
- Massive 3-Row Core: Features a 2" thick, 3-row oversized tube and fin core that is 30% larger than the factory radiator, significantly increasing coolant capacity and surface area for optimum cooling efficiency.
- Heavy-Duty Aluminum End Tanks: Fabricated from 1/8" thick aircraft-grade aluminum plates, offering superior strength and structural integrity over fragile stock plastic tanks.
- CNC-Machined Billet Connections: Equipped with CNC-machined billet aluminum inlet and outlet ports to provide long-lasting, leak-free reliability under high-pressure conditions.
- 100% TIG-Welded Seams: All joints and structural seams are 100% TIG-welded by hand, ensuring proven track-ready strength and maximum durability against vibration.
- Premium Brass Drain Valve: Includes a heavy-duty brass drain valve featuring a thread-in fitting, allowing you to easily connect a hose for clean, hassle-free coolant flushes.
- High-Pressure Radiator Cap: Comes complete with an upgraded 18psi radiator cap to raise the boiling point of your coolant and improve overall system efficiency.
- Perfect Drop-In Fit: Utilizes the stock factory mounting locations to ensure a stable, secure, and straightforward installation process without modifications.
- Custom Styling: Finished with a clean, brushed aluminum appearance and a painted AFE Power logo on the front face for a premium look under the hood.
From an educational standpoint, understanding how heat rejection works is key to recognizing the value of a 30% larger core. In a diesel engine, the larger the volume of the radiator's tubes and fins, the more heat the system can pull away from the engine block simultaneously. The larger tube and fin core design of the BladeRunner Street Series slows down the rate of heat soak, meaning your truck maintains cooler operating temperatures over a much longer range of time, even during extended uphill heavy towing. By pairing this expanded thermal capacity with rugged aircraft-grade aluminum construction and a higher-pressure 18psi cap, AFE delivers a cooling upgrade that doesn't just replace your leaking stock unit—it completely re-engineers your truck's thermal management for long-term peace of mind.
