Constant thermal cycling, combined with the compact engine bay of full-size vans, leads to accelerated plastic embrittlement, cracked end tanks, and leaky crimp seals. Under continuous low-speed idling or heavy payload demands, the restricted core volume allows coolant temperatures to climb rapidly, placing excessive thermal strain on both the 4.3L Vortec engine and the automatic transmission.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis heavy-duty unit features a 3-row crossflow core constructed from 100% brazed aluminum with precision TIG-welded end tanks, eliminating mechanical crimp gaskets entirely. The multi-louvered fin and three-tier tube design significantly increases surface heat dissipation and coolant capacity over OEM single-row units. An integrated high-efficiency automatic transmission fluid cooler ensures fluid temperatures remain stabilized, protecting clutch packs and valves during sustained load cycles.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px;\"\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eFitment\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e2003-2005 GMC Savana 1500 \/ 2500\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eEngine \/ Chassis\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e4.3L Vortec 4300 (LU3) \/ GMT610\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eStock Output\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e195 hp \/ 260 lb-ft (Approx)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eCore Dimensions\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e17-1\/4\" H x 30-1\/2\" W (3-Row Crossflow)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eInlet \/ Outlet\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e1.34 in \/ 1.57 in\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eDPI 2716 \/ CU2716 \/ 89019164 \/ 15751212\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2003 GMC Savana 1500 4.3L V6 Automatic (Transmission Oil Cooler Included)\u003c\/li\u003e\n  \u003cli\u003e2004 GMC Savana 1500 4.3L V6 Automatic (Transmission Oil Cooler Included)\u003c\/li\u003e\n  \u003cli\u003e2005 GMC Savana 1500 4.3L V6 Automatic (Transmission Oil Cooler Included)\u003c\/li\u003e\n  \u003cli\u003e2003 GMC Savana 2500 4.3L V6 Automatic (Transmission Oil Cooler Included)\u003c\/li\u003e\n  \u003cli\u003e2004 GMC Savana 2500 4.3L V6 Automatic (Transmission Oil Cooler Included)\u003c\/li\u003e\n  \u003cli\u003e2005 GMC Savana 2500 4.3L V6 Automatic (Transmission Oil Cooler Included)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe GMC Heavy-Duty Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to handle sustained commercial hauling, fleet transport, and towing environments, this all-aluminum drop-in replacement delivers bulletproof cooling reliability without fitment modifications.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50426440515832,"sku":"DS-EPH5E07PH","price":234.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/performance-radiator-for-gmc-savana-2003-2005-4-3l-automatic-1.jpg?v=1788398544","url":"https:\/\/performancechiptuning.com\/products\/performance-radiator-for-gmc-savana-2003-2005-4-3l-automatic","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
