Mishimoto Performance Aluminum Radiator: Ram 2500 / Ram 3500 2019-2024

Mishimoto Performance Aluminum Radiator

2019–2024 Ram 2500 / Ram 3500 6.7L Cummins

MMRAD-RAM-19

Overview:

The Mishimoto Performance Aluminum Radiator is a premium cooling upgrade designed specifically for the 2019 to 2024 Ram 2500 and Ram 3500 trucks equipped with the 6.7L Cummins engine. Known for its legendary reliability and power, the Cummins-powered Ram is a workhorse built to handle heavy-duty tasks. However, the stock radiator’s plastic end tanks are prone to cracking and leaking under stress, especially when hauling or towing demanding loads. Mishimoto’s all-aluminum radiator addresses these weaknesses by offering enhanced durability and superior cooling performance, ensuring your Ram stays cool and reliable no matter the workload.

Engineered to withstand the rigors of heavy use, this radiator is an ideal upgrade for owners who demand more from their trucks. Whether you’re towing, hauling, or working in extreme conditions, the Mishimoto radiator provides peace of mind with increased fluid capacity and robust construction.

Key Features:

Designed to maximize cooling efficiency and durability, the Mishimoto Performance Aluminum Radiator offers the following key benefits:

• Durable fully aluminum construction with TIG-welded end tanks and fittings for superior strength and leak resistance
• 28% increase in fluid capacity compared to stock radiators, improving heat dissipation under heavy loads
• Includes replacement bushings to ensure a secure fit and reduce vibration from worn or damaged factory bushings
• Direct fitment for a wide range of Ram 2500 and Ram 3500 trims from 2019 through 2024, including Big Horn, Laramie, Limited, Rebel, Tradesman, and more
• Engineered specifically for the 6.7L Cummins diesel engine to optimize cooling performance

Construction & Design:

The Mishimoto radiator is crafted from high-quality aluminum, chosen for its excellent thermal conductivity and lightweight strength. The TIG-welded end tanks and fittings provide a robust, leak-resistant seal that outperforms the fragile plastic end tanks found on stock radiators. This all-aluminum design not only enhances durability but also improves heat transfer efficiency, helping to maintain optimal engine temperatures during demanding driving conditions.

With a 28% increase in coolant capacity, this radiator offers greater thermal mass to absorb and dissipate heat more effectively. This design reduces the risk of overheating during heavy towing, hauling, or extended idling, making it a reliable choice for work and off-road environments.

Installation & Fitment:

The Mishimoto Performance Aluminum Radiator is a direct replacement for the factory radiator on 2019–2024 Ram 2500 and Ram 3500 models equipped with the 6.7L Cummins engine. Installation requires no modifications, making it a straightforward upgrade for DIY enthusiasts and professional installers alike. The included replacement bushings help ensure a secure and vibration-free fit, even if the original bushings are worn or damaged.
