Over continuous thermal cycling and elevated operating pressures, these polymer composite tanks become brittle, causing micro-cracking at the inlet neck and seam separation. Under sustained towing or stop-and-go summer loads, the slim single-row core quickly heat-soaks, triggering elevated transmission and engine oil temperatures.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eConstructed from high-grade AA5052 aircraft aluminum with 100% precision TIG-welded tanks, this 3-row performance radiator completely eliminates fragile plastic and gasket joints. The multi-louvered 3-row core maximizes surface area and heat dissipation capacity, backed by integrated transmission and engine oil coolers to protect vital drivetrain components under maximum load.\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;\"\u003e2015-2020 Chevrolet Suburban\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;\"\u003e5.3L EcoTec3 L83 \/ K2XX Platform\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;\"\u003e355 hp \/ 383 lb-ft (Approx)\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;\"\u003eDPI13398 \/ CU13398 \/ RAD13398 \/ 23126402\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2015-2020 Chevrolet Suburban 5.3L V8 (LS, LT, Premier)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Chevrolet Heavy-Duty Caliber\u003c\/h3\u003e\n\u003cp\u003eBuilt to withstand extreme hauling and heavy payload demands, this drop-in cooling assembly maintains rock-solid thermal stability across severe duty cycles without requiring modification to factory fan shrouds or mounting brackets.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50461756489976,"sku":"DS-EO95KCSHR","price":298.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/aluminum-radiator-for-chevrolet-suburban-2015-2020-5-3l-1.jpg?v=1788825192","url":"https:\/\/performancechiptuning.com\/products\/aluminum-radiator-for-chevrolet-suburban-2015-2020-5-3l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
