MMRAD-RAM-03

Overview:

The Mishimoto Performance Aluminum Radiator is a premium cooling solution engineered specifically for Dodge Ram trucks equipped with 5.9L and 6.7L Cummins engines from 2003 to 2009. Designed to replace the factory radiator, this upgrade enhances cooling efficiency to protect your engine under demanding conditions. Whether you rely on your Dodge Ram for daily driving, heavy towing, or hauling, this radiator ensures your engine stays cool and performs reliably even under extreme heat and load.

Factory radiators often struggle to dissipate the heat generated by high torque and power outputs, which can lead to overheating and reduced engine longevity. Mishimoto’s radiator addresses these challenges with advanced materials and design, providing a durable, high-performance cooling component that maintains optimal engine temperatures.

Key Features:

Engineered for durability and superior cooling performance, the Mishimoto Performance Aluminum Radiator offers the following key features:

• Lightweight two-row core constructed from 100% brazed aluminum for efficient heat dissipation
• Strong TIG-welded aluminum end tanks for enhanced structural integrity and longevity
• Direct factory fit design ensures a seamless replacement with no cutting or modifications required
• Optimized core design maximizes coolant flow and cooling surface area
• Includes a magnetic drain plug to capture metal particles and extend engine life
• Backed by Mishimoto’s signature lifetime warranty for peace of mind
• Compatible with Dodge Ram 2500 and 3500 models from 2003 to 2009, as well as Ram 4500 and 5500 models from 2008 to 2009

Construction & Design:

The radiator is crafted entirely from high-quality aluminum, chosen for its excellent thermal conductivity and corrosion resistance. The two-row core is brazed to ensure a leak-free, robust structure capable of withstanding the rigors of heavy-duty use. TIG welding on the end tanks further enhances durability, preventing cracks and leaks that can occur under high pressure and temperature fluctuations.

This meticulous construction not only improves cooling efficiency but also reduces overall weight compared to traditional copper-brass radiators, contributing to better vehicle performance and fuel economy.

Installation & Fitment:

Installation is straightforward thanks to the radiator’s direct-fit design tailored to the factory mounting points of the specified Dodge Ram models. No cutting, trimming, or additional modifications are necessary, allowing for a hassle-free upgrade. This makes it an ideal choice for both professional mechanics and DIY enthusiasts looking to improve their truck’s cooling system quickly and reliably.
