Core specifications & fitment details

Aluminum Core Construction & Engineering
The DNA Motoring OEM RA-1702 aluminum replacement radiator features a fully welded aluminum construction that outperforms traditional copper-brass designs in both weight and thermal efficiency. Our engineering team selected aircraft-grade aluminum alloys for the core, tanks, and header plates to ensure maximum corrosion resistance and heat transfer.
Every DNA Motoring RA-1702 undergoes a precision brazing process that bonds the tube-and-fin matrix without compromising material integrity. This manufacturing method creates a uniform thermal pathway that rapidly moves heat from coolant to ambient air, preventing hot spots and maintaining stable engine temperatures even during extended high-load operation.

Direct-Fit Installation & Compatibility
We engineered the RA-1702 as a true plug-and-play OEM replacement, with every mounting bracket, inlet/outlet port, and sensor provision machined to match your vehicle’s factory radiator exactly. The radiator ships with pre-drilled mounting holes aligned to OEM specifications, eliminating the need for modification or custom fabrication during installation.
Fitment Verification
Before ordering your DNA Motoring OEM RA-1702 aluminum replacement, confirm your vehicle’s year, make, model, and engine size against our compatibility chart. Our radiators are application-specific, ensuring proper coolant capacity, hose connection angles, and fan clearance for your exact vehicle configuration.
Performance Specifications & Cooling Capacity
The RA-1702 radiator provides a calculated cooling capacity that matches OEM thermal load requirements for your specific vehicle application. Our core design incorporates optimized tube dimensions and fin spacing to balance coolant flow rate with heat rejection efficiency, ensuring your engine maintains target operating temperature across all driving scenarios.
Core Dimensions & Flow
The radiator’s core measures to OEM specifications for height, width, and thickness, maintaining factory coolant volume while improving thermal transfer through enhanced fin geometry. Internal baffling promotes even coolant distribution across all tube rows, preventing channeling that can reduce cooling effectiveness in standard radiators.

Questions About the RA-1702 Radiator
The DNA Motoring OEM RA-1702 aluminum replacement is application-specific and designed to fit certain vehicle makes, models, and engine configurations. Before purchasing, verify your vehicle’s year, make, model, engine size, and transmission type against our compatibility chart to ensure proper fitment.
The radiator features OEM-exact mounting points, inlet/outlet positioning, and sensor provisions for its intended applications. If your vehicle matches the compatibility specifications, installation requires no modification to mounting brackets or cooling system plumbing.
Aluminum radiators like the RA-1702 offer superior heat transfer efficiency per unit weight compared to traditional copper-brass designs. The aluminum core dissipates heat more rapidly while weighing 30-40% less than equivalent copper-brass radiators, reducing front-end weight and improving vehicle dynamics.
Aluminum construction also provides better corrosion resistance when proper coolant chemistry is maintained. The brazed tube-and-fin design creates a stronger structural matrix that withstands vibration and thermal cycling better than soldered copper-brass cores, typically resulting in longer service life.
Installing the DNA Motoring RA-1702 requires basic hand tools including socket sets, wrenches, screwdrivers, and pliers. You’ll need a drain pan for old coolant, fresh 50/50 premixed antifreeze to refill the system, and we recommend replacing radiator hoses and clamps during installation.
The job typically takes 2-4 hours depending on your vehicle’s front-end configuration and your mechanical experience. You’ll need to drain the cooling system, remove the old radiator, transfer fan shrouds and sensors to the new unit, install the RA-1702, reconnect hoses, and refill/bleed the system following standard cooling system service procedures.
Yes, every DNA Motoring OEM RA-1702 aluminum replacement radiator undergoes pressure testing to 20 PSI before leaving our facility. This quality control step verifies the integrity of all brazed joints, welded seams, and crimped connections under pressure exceeding normal cooling system operating levels.
The radiator ships with protective caps installed over inlet and outlet ports to prevent contamination during shipping. Remove these caps immediately before installation and perform a visual inspection of the core and tanks for any shipping damage before proceeding with your installation.
The RA-1702 is designed as a direct replacement for your factory radiator and works with all existing cooling system components including hoses, fan assemblies, shrouds, overflow tanks, and sensors. You’ll transfer these components from your original radiator to the new unit during installation.
We recommend inspecting hoses, clamps, and thermostat condition during radiator replacement and replacing any components showing age-related deterioration. Using fresh coolant and ensuring proper system chemistry maximizes the aluminum radiator’s corrosion resistance and long-term performance.
Use a 50/50 mixture of ethylene glycol antifreeze and distilled water, or purchase premixed coolant meeting your vehicle manufacturer’s specifications. The aluminum construction requires proper coolant chemistry to prevent electrolytic corrosion between dissimilar metals in your cooling system.
Avoid using straight water or incorrect coolant ratios, as these can accelerate corrosion and reduce freeze/boil protection. Replace coolant every 30,000 miles or 24 months to maintain optimal corrosion inhibitor levels and heat transfer properties throughout the radiator’s service life.
With proper coolant maintenance and normal operating conditions, the DNA Motoring RA-1702 aluminum radiator typically provides 100,000+ miles of reliable service. The all-aluminum construction eliminates plastic tank failure common in factory radiators, while the brazed core design resists the fatigue cracks that affect soldered copper-brass units.
Longevity depends on maintaining correct coolant chemistry, protecting the core from road debris impact, and avoiding overpressure events from cooling system malfunctions. Regular coolant changes and periodic external cleaning help maximize service life and maintain optimal cooling performance.
