Product Details

The Mishimoto MMRAD-RAM-03 is a high-performance aluminum radiator engineered specifically for 2003-2009 Dodge Ram trucks equipped with 5.9L or 6.7L Cummins diesel engines. This direct-fit upgrade provides superior cooling capacity over the factory radiator, making it ideal for stock trucks, towing applications, or modified performance builds.

Key Features:

  • Two-row brazed aluminum core construction for maximum heat dissipation efficiency
  • Full aluminum design with durable TIG-welded end tanks for long-lasting reliability
  • Increased coolant capacity compared to stock radiator for improved thermal management
  • Includes 1.3 bar high-pressure radiator cap that raises coolant boiling point for safer, more efficient operation
  • Magnetic drain plug captures metallic debris and fragments from the cooling system
  • Direct bolt-in replacement with no modifications required
  • Backed by Mishimoto's Lifetime Warranty

Whether you're towing heavy loads, hauling equipment, or pushing your Cummins to its limits, this aluminum radiator delivers the efficient temperature regulation needed to keep your diesel running cool under demanding conditions. The increased fluid capacity and optimized core design work together to provide consistent cooling performance that exceeds OEM specifications.

Over $150 cheaper than the last lift kit I ordered! Impressed!

Smooth

It was great

Awesome service. After having 2 other orders from other suppliers cancelled without any notification, it was a pleasure doing business with autoplicity. Thank you!

I looked all over the web for the Thule sidekick car top carrier and autoplicity had the best price and the website was easy to maneuver through. It willbe my first stop for shopping.

Am happy with price, lower than anywhere else. Product is perfect and shipping was fast. Had to call because website was down while price increases were uploaded, cost an extra $20 but still worth the savings. Would definitely buy from again.

Excellent e-merchant. Awesome service, great products and super low prices !!!

So far so good
