The XDP Xtra Cool Direct-Fit Replacement Radiator XD295 is an upgrade for the old leaking radiator in your 2001-2005 GM 6.6L Duramax LB7 & LLY. While the Xtra Cool may resemble a stock replacement, the construction and design is far from it! The Xtra Cool Radiators are specially designed with upgraded techniques borrowed from the semi-truck and HD industry. Unlike the OEM radiator, extra steps are taken to ensure added durability and strength to protect your cooling system. 

High Efficiency Core
XDP's Xtra Cool Radiators are built with a high efficiency core that has 18 fins per inch over the factory 16 fins per inch, and heavy-duty tubes to maximize cooling capabilities. 

Internal Reinforcements
For added strength, special aluminum brazing techniques are used during construction. The reinforced end tubes and added strength at the outside corners protect the core where it is most vulnerable.

Gasket Design
Xtra Cool Radiators feature a proprietary rubber gasket designed to withstand expansion, contraction, and the flex in the front end of your truck. 

Revised End Tanks
Reinforcement ribs are strategically added to the end tanks to strengthen weak points. The plastic mix includes a fiber reinforcement that is added during tank construction to provide more strength over the factory tanks.

Upgraded Mounting Points
To allow the Xtra Cool Radiator to stay securely mounted in the same factory location as the stock radiator, the mounting points have been upgraded for added strength and longevity. 

Tank Attachment
To attach the end tanks to the core on the Xtra Cool Radiator, a heavy gauge steel crimp strip is used instead of aluminum like the factory design. The heavy duty crimp helps eliminate tank and core separation failures that many experience with the factory radiator.

Only Dmax Radiator we install
Been super happy with the radiator for Dmax's from these guys. Cross multiple generations, all fit great, and seems to be a nice upgrade to factory units.

Great Product So Far!
I've only racked up a whopping 100 miles on this new radiator, but the quality was fantastic! The only complaint I had was that we had to switch out the trans cooler fittings (Provided with the radiator) to fit the stock lines from my truck and those things were stupid tight. Once they were swapped out, the install went very well and the only other issue I had was getting the overflow tube to tighten enough on the radiator as the stock spring wouldn't clamp it down enough to stop it from leaking.
