Description

The J2 Engineering Performance Aluminum Radiator is engineered to provide superior cooling for modified engines, older vehicles with inadequate stock systems, or as an upgrade during replacement. Its 1-row racing specification core and larger coolant capacity contribute to a significant improvement in cooling efficiency, reportedly between 35-45% higher than stock units. The core measures 28.25 inches x 18.75 inches x 1.00 inch, with inlet and outlet sizes of 1.25 inches and 1.50 inches respectively. This radiator is designed as a direct, bolt-on OEM fitment or replacement, simplifying installation. It is compatible with 2000-2007 GMC Yukon AT, 2000-2006 GMC Yukon XL 1500 AT, 1999-2006 GMC Sierra 1500 AT, 1999-2000 GMC Sierra 2500 AT, and 2002-2005 Cadillac Escalade AT models. Crucially, it only fits models with a 28-inch core radiator and is exclusively for Automatic Transmission models equipped with 4.8L or 5.3L V8 engines.
