DNA Motoring RA-FM79-3 Aluminum Radiator
Our RA-FM79-3 aluminum radiator delivers superior cooling performance for enthusiasts who demand reliable thermal management. Engineered with multi-row core construction and lightweight aluminum tanks, this direct-fit replacement radiator improves heat dissipation efficiency over stock units.
Whether you’re building a street machine or refreshing an aging cooling system, the RA-FM79-3 combines race-proven materials with precision manufacturing. We designed this radiator to drop into place using factory mounting points, eliminating the need for custom brackets or modifications during installation.
Core specifications & fitment details
Full Aluminum Construction & Core Design
The DNA Motoring RA-FM79-3 aluminum radiator features a fully welded aluminum core and end tanks that reduce weight while increasing thermal efficiency. Unlike stock copper-brass radiators that add unnecessary mass, our aluminum construction cuts radiator weight by up to 40% without sacrificing cooling capacity.
Each core uses precision-brazed tube and fin architecture to maximize surface contact with airflow. The multi-row configuration increases coolant volume and residence time within the core, allowing more heat to transfer before fluid returns to the engine block. TIG-welded end tanks eliminate the weak points found in crimped-seam designs, ensuring leak-free operation even under high-pressure conditions.
Direct-Fit Installation & Compatibility
This radiator mounts using factory locations and accepts OEM hose connections, making installation straightforward for DIY builders and professional shops alike. We precision-manufacture each unit to match original equipment dimensions, so you won’t need to modify core supports, trim radiator shrouds, or fabricate custom brackets.
All necessary mounting hardware ships with your radiator, including rubber isolators that protect the core from vibration damage. The dna motoring ra fm79 3 aluminum radiator accepts stock upper and lower radiator hoses without adapters, and our inlet/outlet sizing matches OEM specifications for proper coolant flow.
Performance Testing & Quality Assurance
Every DNA Motoring aluminum radiator undergoes pressure testing before leaving our facility to verify weld integrity and core seal quality. We subject each unit to pressures exceeding factory cooling system specifications, ensuring your radiator will maintain reliability under real-world operating conditions.
The polished aluminum finish not only enhances under-hood appearance but also provides a protective oxide layer that resists corrosion from coolant additives and environmental exposure. We use industry-standard brazing techniques and materials that meet or exceed OEM quality standards, giving you confidence in long-term durability.

Questions About the RA-FM79-3 Radiator
The DNA Motoring RA-FM79-3 aluminum radiator maintains OEM core dimensions and mounting provisions, so it’s compatible with most factory fan setups. The radiator accepts stock fan mounting brackets and clears standard shrouds without modification.
If you’re running an aftermarket electric fan or have modified your cooling system, verify clearances before installation. The core thickness matches factory specifications to ensure proper fitment with existing components.
We recommend using a high-quality ethylene glycol or propylene glycol coolant specifically formulated for aluminum cooling systems. These coolants contain corrosion inhibitors that protect aluminum from oxidation and galvanic corrosion.
Avoid universal coolants that aren’t aluminum-safe, as they can cause pitting and premature failure. Always mix coolant with distilled water at the manufacturer’s recommended ratio, typically 50/50 for most climates. Replace coolant according to the coolant manufacturer’s service intervals to maintain optimal protection.
The dna motoring ra fm79 3 aluminum radiator typically weighs 40-50% less than comparable copper-brass radiators, with exact weight savings depending on your vehicle’s original equipment. Most aluminum radiators weigh between 8-12 pounds, while stock units often exceed 15-20 pounds.
This weight reduction improves front-end weight distribution and reduces unsprung mass, which can benefit handling characteristics. The lighter construction also simplifies installation and reduces stress on mounting points.
Most DIY enthusiasts with basic mechanical skills and hand tools can install the RA-FM79-3 radiator in 2-3 hours. The direct-fit design eliminates custom fabrication, and our included instructions guide you through drain, removal, and installation procedures.
You’ll need a drain pan for coolant, basic wrenches and sockets, and fresh coolant for refilling. If you’re uncomfortable working with cooling systems or your vehicle requires extensive disassembly to access the radiator, professional installation ensures proper fitment and system bleeding.
DNA Motoring backs the RA-FM79-3 aluminum radiator with our standard manufacturer warranty covering defects in materials and workmanship. The warranty protects against manufacturing defects such as weld failures, core leaks, and tank separation under normal operating conditions.
Damage from improper installation, incorrect coolant, physical impact, or operation outside recommended pressure and temperature ranges is not covered. Register your product after purchase and retain proof of purchase for warranty claims.
Yes, the dna motoring ra fm79 3 aluminum radiator typically provides superior cooling performance compared to aging stock radiators. The multi-row core design increases coolant capacity and heat transfer surface area, while the high-flow tube architecture reduces coolant restriction.
Aluminum also conducts heat more efficiently than copper-brass construction, allowing faster thermal transfer from coolant to ambient air. Most customers report 10-20 degree temperature reductions under similar operating conditions, particularly beneficial for modified engines or vehicles used in demanding applications.
The RA-FM79-3 radiator uses inlet and outlet sizing that matches OEM specifications for its intended application, ensuring compatibility with factory hoses and connections. Exact dimensions vary by vehicle fitment, but the radiator accepts stock hose diameters without adapters or modifications.
If you’re upgrading hoses or installing aftermarket cooling components, measure your existing connections before ordering. The 1/8 NPT bungs for temperature sensors are standardized across all units for consistent aftermarket gauge compatibility.
