Compatible Ram Cummins Models

The Mishimoto Performance Aluminum Radiator is compatible with:

• 2013 Ram 2500 6.7L Cummins
• 2014 Ram 2500 6.7L Cummins
• 2015 Ram 2500 6.7L Cummins
• 2016 Ram 2500 6.7L Cummins
• 2017 Ram 2500 6.7L Cummins
• 2018 Ram 2500 6.7L Cummins
• 2013-2018 Ram 3500 6.7L Cummins

Perfect for:

• Heavy-duty tow rigs
• Work trucks
• Tuned diesel builds
• Fleet vehicles
• Long-haul trucks
• High-mileage Cummins setups

Because no Cummins owner leaves the truck stock once they discover torque numbers online.

The legendary reliability and power of the 6.7L Cummins equipped Dodge Ram has solidified it as some of the popular trucks on this planet for getting work done.

Full Aluminum Heavy-Duty Construction

Unlike factory radiators that commonly use:

• Plastic end tanks
• Composite fittings
• Crimped seams

The Mishimoto radiator features:

• Full aluminum construction
• TIG-welded end tanks
• Welded aluminum fittings

This improves:

• Durability
• Pressure resistance
• Cooling efficiency
• Long-term reliability

Because towing 15,000+ pounds while generating diesel torque creates enough vibration and heat to expose weak cooling systems immediately.

But each and every legend has its weakness, and for the Dodge Ram, the stock radiator is one of them. The plastic end tanks of the stock Ram radiator are at risk of cracking and leaks over the years.

Built for Towing & Heavy Hauling

This radiator is especially valuable for:

• Fifth-wheel towing
• RV hauling
• Equipment trailers
• Construction work
• Long-distance towing
• Hot climate operation

Improved cooling helps reduce:

• Coolant temperature spikes
• Thermal fatigue
• Heat-related power loss
• Cooling system strain

Especially when hauling trailers large enough to have their own weather patterns.

Add the increased stress and heat created by power-adding modifications and you have got a recipe for disaster. But that’s where Mishimoto can assist. Our new 2013-2018 Ram 2500 / 3500 radiator is the ideal upgrade for any workhorse Cummins powered Ram.

Ideal for Tuned Cummins Builds

This radiator is perfect for:

• Tuned diesel setups
• Emissions-equipped trucks
• High-torque applications
• Bigger turbo setups
• Heavy-duty street builds

Extra power creates:

• Higher EGTs
• Greater coolant demand
• Increased thermal load
• More engine bay heat

And tuned diesels generate temperatures with the subtlety of a steel mill.

With an absolutely aluminum, TIG-welded construction, this radiator is built as tough as your truck. A 63% increase in coolant capacity, and 41% larger surface area mean you’ll be able to pile on the power and never worry about the heat. As with any of our products, this radiator is backed up by Nishimoto’s Lifetime Warranty. Doesn’t your Ram deserve a radiator worthy of legend?

Massive Cooling Capacity Increase

One of the biggest upgrades is:

• 63% increase in coolant capacity
• 41% increase in cooling surface area

That is a massive thermal improvement over stock.

This helps provide:

• Lower operating temperatures
• Better heat dissipation
• Reduced thermal stress
• Improved sustained cooling

Especially beneficial during:

• Heavy towing
• Summer hauling
• Long mountain climbs
• High-load acceleration
• Extended highway driving

Where factory cooling systems occasionally begin filing emotional complaints internally.

Improved Long-Term Reliability

A larger all-aluminum radiator helps improve:

• Thermal consistency
• Cooling system longevity
• Engine reliability
• Heavy-duty durability

Especially important because:

• Cummins trucks regularly exceed 300,000 miles
• Towing reliability matters enormously
• Overheating heavy-duty diesels becomes expensive very quickly

Because nobody wants cooling system failure halfway through a cross-country tow.

OEM-Style Direct Fit Installation

The radiator is engineered for:

• Direct-fit installation
• Factory hose compatibility
• OEM mounting integration

Typical installation requires:

• Coolant drain
• Socket set
• Hose clamp tools
• Approximately 4-6 hours

No major:

• Fabrication
• Cutting
• Custom mounting typically required

Which is fortunate, because modern diesel engine bays already resemble commercial plumbing systems naturally.

Why Upgrade the Ram Cummins Radiator?

Common reasons owners upgrade radiators include:

• Heavy towing demands
• Tuned diesel cooling needs
• Preventative maintenance
• Long-haul reliability
• High-mileage cooling upgrades
• Extreme climate performance

A performance radiator remains one of the smartest upgrades for heavy-duty diesel trucks because:

• Heat destroys towing reliability quickly
• Modern diesels generate enormous thermal load
• Modified Cummins trucks overwhelm factory cooling systems fast

Especially once trailers and tuning stack together.

Final Verdict

For 2013-2018 Ram 6.7L Cummins owners wanting serious cooling improvements and long-term towing reliability, the Mishimoto Performance Aluminum Radiator delivers major thermal management upgrades with heavy-duty aluminum construction.

Key benefits include:

• 63% greater coolant capacity
• 41% more cooling surface area
• Full aluminum construction
• TIG-welded end tanks
• Improved towing and hauling cooling
• Direct-fit installation

Most importantly, your Cummins finally stops treating every mountain grade like a thermal survival challenge.
