Zynrako Engine Coolant Radiator for Dodge Ram 1500/2500/3500/4000 (2009–2021, 3.6–5.7L) OE-fit Aluminum, Reinforced

Zynrako's aluminum engine coolant radiator is a direct-fit replacement for Dodge Ram trucks (2009–2021) built to match factory performance and resist leaks from vibration and thermal stress.

This radiator is engineered to replace OE# CH3010353 and many related factory part numbers for Ram 1500/2500/3500/4000 models with 3.6L–5.7L gasoline, flex-fuel, MHEV, bi-fuel and CNG engines. It combines reinforced headers, reinforced B-type tubes, and thermal expansion features so the core handles pressure and temperature cycles reliably. Whether you’re repairing a leaking core or restoring cooling capacity after an accident, this unit is designed to bolt in with OE-equivalent fit, finish, and cooling efficiency.

What exact Ram models and engines will this radiator fit?

This radiator covers a broad range of Dodge/Ram applications across model years 2009–2021. Compatibility includes multiple engine types and powertrains commonly found in pickup and heavy-duty Ram lines.

• Ram 1500: 2009–2010 (3.7L/4.7L/5.7L GAS & 4.7L FLEX); 2011–2021 (3.6L/3.7L/4.7L FLEX & 5.7L GAS/MHEV); 2019–2021 Classic (3.6L FLEX, 5.7L GAS).
• Ram 2500: 2009–2010 (4.7L/5.7L GAS); 2011–2013 (4.7L FLEX, 5.7L GAS, 5.7L BI-FUEL/CNG).

How does this radiator match or improve on the original equipment?

Zynrako radiators are built to meet the specifications of the factory units and replace a long list of OEM numbers. Design elements focus on joint strength, core stability, and heat transfer to prevent the common failure modes that affect older radiators.

• Replaces OE numbers including CH3010353 and equivalents (2AMR3129AA, 55056858AB–AE, 55056870AA–AF, 55056972AB, 55057090AB/AC).
• Deep extrusion headers reinforce tube-to-header joints to reduce leak risk under vibration.
• B-type tubes with central reinforcement increase pressure tolerance and core durability.

What engineering features help this radiator last longer?

Several targeted design choices control thermal movement and reinforce core connections, which reduces stress points that lead to leaks and premature failure. These features are practical improvements that extend service life without altering installation procedures.

• Thermal expansion cuts allow controlled core growth during heat cycles, reducing stress on joints.
• Folded fin edges stabilize the fin pack and improve heat dissipation across the core.
• Multi-fit attachment points preserve OE-style mounting and compatibility across trims.

How do I confirm this radiator fits my truck before buying?

Double-checking fitment prevents returns and ensures a hassle-free installation. Use vehicle tools and VIN checks to confirm exact chassis, engine, and accessory compatibility.

• Use the site’s vehicle matching tool or enter your VIN to verify fitment for your specific model year and engine.
• Compare the listed OE replacement numbers to your OEM part tag if available.
• If uncertain, provide your VIN to customer support for rapid, accurate confirmation.

Who is this radiator for? If you own or maintain Dodge Ram trucks from model years 2009 through 2021 and need a dependable, OEM-equivalent cooling core—whether replacing a failed unit, repairing accident damage, or upgrading a worn original—this Zynrako aluminum radiator is built for professional mechanics and DIY technicians seeking long-lasting performance and straightforward fitment. It’s especially suited for vehicles using 3.6L–5.7L gasoline, flex-fuel, hybrid-assisted (MHEV), bi-fuel, or CNG systems where the correct factory replacement part is required.
