Description
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.

Over all great quality part. Packaging could survive a nuclear blast which was great. Only reason it’s not 5 stars is because it didn’t come with a sticker.

Radiator seems good quality, but the instructions were dismal. Came with transmission cooler adapters that had to be changed for my model and they did not have the required stainless washers so I had to remove the ones of the other fittings. When I called customer service and left my phone number for a return call I never heard from them. Good thing It works. Good product not so good customer service.

Ordered this to update from factory. The reason for the 4 starts is I was not impressed with the transmission cooler connectors that came with the kit. Had to source some locally for my install. The tranny cooler set up in the tank is also shifty. As far as the cooling of the rad I was extremely impressed dropped 10deg on the average on the trans and the eng coolant temps.
