Mishimoto Aluminum Radiator

2010–2012 Dodge Ram 2500 / 3500 6.7L Diesel

Part #: MMRAD-RAM-10

The Mishimoto Aluminum Radiator is a premium cooling upgrade designed specifically for Dodge Ram 2500 and 3500 trucks equipped with the 6.7L Cummins diesel engine from 2010 through 2012. Engineered as a direct replacement for the factory radiator, this high-performance unit addresses the intense cooling demands of diesel-powered trucks used in towing, hauling, and heavy-duty applications.

By increasing coolant capacity and enhancing heat dissipation, the Mishimoto radiator helps prevent overheating and maintains optimal engine temperatures even under extreme conditions. Whether your Ram is a daily driver or a workhorse, this radiator improves engine reliability and longevity by efficiently managing the heat generated by the powerful Cummins diesel.

Key Features

Combining advanced engineering with durable materials, the Mishimoto Aluminum Radiator delivers superior cooling performance and long-lasting reliability. Key features include:

• Direct factory fitment for effortless installation with no cutting or modifications required
• 64% increased coolant capacity compared to the stock radiator for enhanced heat absorption
• 100% brazed aluminum core that is 19% thicker than the factory radiator for improved durability and cooling efficiency
• Robotic TIG-welded aluminum end tanks providing superior strength and leak resistance
• Strategically designed side plates on the end tanks to optimize airflow through the core
• Brushed aluminum finish offering corrosion resistance and a clean, professional appearance
• Includes two rubber mounting bushings to reduce vibration and ensure secure fitment
• Equipped with a Mishimoto M12 x 1.5mm magnetic drain plug to capture metal fragments and protect the cooling system
• High-pressure radiator cap included to maintain proper system pressure and prevent coolant loss
• Backed by the Mishimoto Lifetime Warranty for peace of mind

Construction & Design

Constructed entirely from 100% brazed aluminum, this radiator balances lightweight design with exceptional strength. The two-row core is 19% thicker than the original equipment manufacturer (OEM) radiator, allowing for greater coolant volume and more efficient heat transfer. The end tanks are precision TIG-welded using robotic technology, ensuring consistent weld quality and durability under high-pressure conditions.

Strategic side plates on the end tanks channel airflow directly into the radiator core, maximizing cooling efficiency. The brushed aluminum finish not only resists corrosion but also adds a sleek, professional look under the hood. Every design element focuses on enhancing performance while maintaining long-term reliability in demanding diesel truck environments.

Installation & Fitment

This radiator is engineered as a direct factory replacement for 2010–2012 Dodge Ram 2500 and 3500 models equipped with the 6.7L Cummins diesel engine. Installation is straightforward and requires no cutting, trimming, or modifications to existing mounting points or hoses. The included rubber mounting bushings reduce vibration and ensure a secure fit, while the magnetic drain plug simplifies coolant changes and system maintenance.

Owners can expect a hassle-free upgrade experience that improves cooling performance without compromising factory fitment or vehicle aesthetics.
