Thumbnail Filmstrip of LBZ|LMM Duramax Aluminum Performance Radiator Cold Case GMT575A Images
Replace a leaking 2006-2010 Duramax radiator before a cracked plastic tank empties the system. The stock tanks are crimped on, and that crimp is the joint that lets go. A fresh radiator can still seep at the lower hose if the old O-ring is reused. Cold Case GMT575A uses TIG-welded aluminum tanks on a two-row core, and the fan shroud is in the box.
- Core: Two 1-inch tubes and 16 corrugated fins per inch fill a core that is 23 inches tall, 34 inches wide, and 3 inches thick.
- Part number: Cold Case GMT575A fits 2006-2010 Chevrolet and GMC trucks with the 6.6L Duramax, LBZ and LMM.
- Mounting size: Overall height is 25 inches and overall width is 45 inches at the brackets. The upper hose is 1.75 inches, the lower hose is 2 inches, and the transmission cooler fitting is 7/8-14 UNF.
- Shroud: The fan shroud is included, so the fan still seals to the core without a separate shroud.
- Not in the box: The lower-hose O-ring is not included. Cold Case calls for a Dorman 926-160 O-ring on the lower hose.
- Does not fit: 2001-2005 or 2011-and-later Duramax trucks. Those years use a different radiator.
- Pressure test: The radiator is pressure tested.
- Warranty: Cold Case covers this radiator against material and workmanship defects for the life of the radiator.
