Massive 3-Row Cooling Core

One of the biggest upgrades is the:

• Thick 3-row aluminum cooling core

Specifications include:

• Overall size: 45.4” x 21.9” x 4.8”
• Core size: 36.42” x 19.21”
• Core thickness: 2.44”
• Inlet size: 1.77”
• Outlet size: 1.97”
• Tank wall thickness: 0.08”

This dramatically improves:

• Heat dissipation
• Coolant capacity
• Thermal stability
• Airflow efficiency

Especially beneficial during:

• Heavy towing
• Long uphill grades
• Hot climate operation
• High boost pulls
• Continuous hauling

Where factory cooling systems occasionally begin spiritually overheating.

Mishimoto has released a right away-have compatibility performance aluminum radiator for the 1994-2002 Dodge 5.9L Cummins.A prime-performance truck wishes a cooling system that may stay alongside of the constant abuse of towing, hauling, and runs at the drag strip.Mishimoto radiators feature a brazed aluminum core with TIG-welded end tanks for superior durability, reliability, and function.Each Mishimoto performance radiator is a right away factory have compatibility, making installation effortless and not using a cutting or modification required.Included with the Mishimoto Cummins aluminum radiator is our magnetic drain plug and signature lifetime warranty.

Compatible Dodge Ram Models

The Mishimoto Performance Aluminum Radiator is compatible with:

• 1994 Dodge Ram 5.9L Cummins
• 1995 Dodge Ram 5.9L Cummins
• 1996 Dodge Ram 5.9L Cummins
• 1997 Dodge Ram 5.9L Cummins
• 1998 Dodge Ram 5.9L Cummins
• 1999 Dodge Ram 5.9L Cummins
• 2000 Dodge Ram 5.9L Cummins
• 2001 Dodge Ram 5.9L Cummins
• 2002 Dodge Ram 5.9L Cummins

Including:

• 12V Cummins models
• 24V Cummins models

Perfect for:

• Tow rigs
• Farm trucks
• Daily-driven diesels
• Compound turbo builds
• Heavy-hauling work trucks
• High-horsepower Cummins setups

Because no second-gen Cummins stays stock after the first conversation about injectors.

Full Aluminum Heavy-Duty Construction

Unlike factory radiators that commonly use:

• Aging OEM materials
• Crimped seams
• Weak factory components

The Mishimoto radiator features:

• Full aluminum construction
• Welded aluminum tanks
• Reinforced cooling structure

Helping improve:

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

Because towing massive loads with old diesel trucks exposes weak cooling systems immediately.

Perfect for Towing & Heavy Hauling

This radiator is especially valuable for:

• Fifth-wheel towing
• Equipment trailers
• Construction use
• Farm hauling
• RV towing
• Heavy work applications

Improved cooling helps reduce:

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

Especially when towing trailers large enough to have their own zip code emotionally.

Ideal for Tuned Cummins Builds

This radiator is also excellent for:

• Bigger injector setups
• Compound turbo systems
• Tuned 12-valves
• High-horsepower diesel builds
• Street-performance trucks

Extra fueling and boost create:

• Higher EGTs
• Greater coolant demand
• Increased thermal load
• Elevated engine bay temperatures

And modified Cummins trucks produce enough heat to qualify as mobile industrial plants.

Better Reliability for High-Mileage Trucks

A larger aluminum radiator helps improve:

• Long-term cooling stability
• Engine reliability
• Towing consistency
• Preventative maintenance durability

Especially important because:

• Most second-gen Rams now have high mileage
• Original cooling systems are aging
• Many trucks still work daily despite surviving decades of abuse

Pure diesel stubbornness is honestly impressive.

OEM-Style Direct Fit Installation

The radiator is engineered for:

• Direct-fit installation
• OEM hose compatibility
• Factory 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 old diesel truck projects already become “while I’m here” disasters immediately.

Why Upgrade the 5.9 Cummins Radiator?

Common reasons Cummins owners upgrade radiators include:

• Heavy towing demands
• Aging OEM radiator failure
• High-mileage preventative maintenance
• Tuned diesel cooling needs
• Extreme climate operation
• Long-haul reliability

A performance radiator remains one of the smartest upgrades for older diesel trucks because:

• Heat destroys towing reliability quickly
• Modified diesels create enormous thermal load
• Old factory cooling systems were never designed for modern power levels

Especially once compounds and fueling upgrades enter the conversation.

Final Verdict

For 1994-2002 Dodge Ram 5.9L Cummins owners wanting serious cooling improvements and long-term reliability, the Mishimoto Performance Aluminum Radiator delivers major thermal management upgrades with heavy-duty aluminum construction.

Key benefits include:

• Thick 3-row cooling core
• Full aluminum construction
• Improved heat dissipation
• Better towing stability
• Ideal for tuned diesel builds
• Direct-fit installation

Most importantly, your Cummins finally stops treating every mountain pull like a thermal endurance event.
