Aluminum Core Construction and Cooling Efficiency
The DNA Motoring OEM RA-13091 aluminum replacement uses a multi-row tube-and-fin core design that maximizes surface area for coolant exposure. Aluminum transfers heat approximately three times faster than traditional copper-brass cores, allowing the RA-13091 to maintain optimal engine temperatures even during extended highway cruising or stop-and-go traffic.
We manufacture each core with precision-formed tubes and corrugated fins that promote turbulent coolant flow, increasing thermal exchange efficiency. The lightweight aluminum construction reduces radiator weight by up to 40% compared to older copper-brass units, which helps lower front-end mass and improve handling balance.
Direct-Fit Installation and OEM Compatibility
The RA-13091 is engineered as a drop-in replacement for specific vehicle applications, matching factory radiator dimensions and mounting configurations. We precision-measure each mounting bracket location to ensure perfect alignment with your chassis radiator support and fan shroud bolt points.
Installation requires no cutting, welding, or custom fabrication—simply unbolt your old radiator, transfer the fan shroud if applicable, and bolt the RA-13091 into place using the included hardware kit. All coolant hose connections match OEM inner diameters, so your existing upper and lower hoses attach securely without adapters or modifications.
Pre-Installation Inspection and What’s Included
Every DNA Motoring OEM RA-13091 aluminum replacement ships after passing a multi-point pressure test that verifies core integrity and tank seal quality. We inspect each unit for fin damage, tube blockages, and mounting tab alignment before packaging.
Your RA-13091 radiator arrives with a complete hardware kit that includes mounting bushings, drain plug with washer, and inlet/outlet gaskets. We also include detailed torque specifications for drain plug installation and a bleeding procedure guide to help you purge air pockets from the cooling system during the first fill.

Common Questions About the RA-13091 Radiator
The DNA Motoring OEM RA-13091 aluminum replacement is designed as a direct-fit part for specific vehicle applications, matching factory inlet/outlet positions and mounting points. Your stock upper and lower radiator hoses will connect to the RA-13091 using the same clamp positions as the original radiator.
If your vehicle uses a plastic fan shroud, it typically bolts to the radiator’s mounting tabs just as it did with the factory unit. Always verify your vehicle’s year, make, model, and engine size against our fitment chart to ensure compatibility before ordering.
We recommend using ethylene glycol or propylene glycol-based coolant formulated for aluminum engines, mixed at a 50/50 ratio with distilled water. Aluminum radiators require coolant with proper corrosion inhibitors to prevent electrolytic corrosion between the aluminum core and other metal components in your cooling system.
Avoid using pure water or coolant mixtures weaker than 40% antifreeze, as these lack sufficient corrosion protection. Always flush the old coolant completely before installing the RA-13091 to prevent contamination from rust particles or degraded inhibitors.
The RA-13091 is engineered to match OEM radiator dimensions for specific vehicle platforms, including overall height, width, depth, and mounting bracket spacing. Before ordering, check our fitment guide for your exact year, make, model, and engine configuration.
If your vehicle is listed as compatible, the radiator will drop into the factory radiator support without cutting, welding, or relocating components. Hose connections align with stock positions, and mounting holes match chassis bolt patterns for a true bolt-in installation.
DNA Motoring backs the RA-13091 aluminum replacement with a limited warranty covering manufacturing defects in materials and workmanship. This includes core leaks from faulty tube joints, tank cracks due to material flaws, and mounting bracket failures under normal use.
The warranty does not cover damage from improper installation, physical impact, use of incompatible coolant, or operation in vehicles outside the specified fitment range. Always follow the included installation instructions and maintain proper coolant levels to keep your warranty valid.
Most mechanically inclined drivers can install the RA-13091 in 2-3 hours using standard hand tools like socket wrenches, screwdrivers, and a drain pan. The process involves draining the old coolant, unbolting the factory radiator, transferring the fan shroud if applicable, and bolting the new unit into place.
You’ll need to refill the system with fresh coolant and bleed air pockets by running the engine with the radiator cap off until the thermostat opens. If you’re uncomfortable working with coolant systems or don’t have a way to safely dispose of old antifreeze, we recommend having a professional shop handle the installation.
Your RA-13091 order includes the aluminum radiator, a complete hardware kit with mounting bushings, a drain plug with sealing washer, and inlet/outlet gaskets. We also provide torque specifications for the drain plug and a bleeding procedure guide to help you purge air from the cooling system.
The radiator arrives factory-tested for leaks and ready to install. You’ll need to supply your own coolant, distilled water for mixing, and basic hand tools. We recommend purchasing new hose clamps if your existing ones show signs of rust or weakening.
Aluminum transfers heat approximately three times faster than copper-brass, making it highly effective for dissipating engine heat in modern cooling systems. The RA-13091’s aluminum core also weighs up to 40% less than traditional copper-brass radiators, reducing front-end weight.
Aluminum radiators resist corrosion better when paired with proper coolant, and the RA-13091’s tube-and-fin design maximizes surface area for efficient thermal exchange. For street-driven vehicles operating at stock power levels, the RA-13091’s aluminum construction provides equivalent or superior cooling compared to aging factory copper-brass units.
