Direct-fit performance aluminum radiator for the 2003-2009 Toyota 4Runner and Lexus GX470 with the 4.7L V8, built to handle the added heat of off-road use where the aging factory radiator can leak, corrode, or clog. The 40mm-thick core increases cooling capacity, and full aluminum construction with TIG-welded end tanks integrates a liquid-to-liquid stacked-plate transmission cooler for transmission fluid temperature control. A magnetic drain plug captures metallic debris in the cooling system.
