Decades of heat cycling harden the plastic tanks, making them susceptible to stress cracks, separation at the core seam, and sudden coolant dumping. Furthermore, high thermal loads from the cast-iron small block quickly heat-soak factory core capacities when hauling or idling on trails.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis unit provides a durable, all-aluminum drop-in replacement. Featuring a high-density 3-row brazed core measuring 33.98 x 17.24 x 1.34 inches, it significantly increases coolant volume and heat dissipation surface area over OEM units. Both tanks are 100% precision TIG-welded to the core, eliminating brittle plastic and failure-prone rubber gaskets entirely for sustained reliability under high-stress operating environments.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1x 3-Row Full Aluminum Radiator\u003c\/li\u003e\n  \u003cli\u003e1x Radiator Cap\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv style=\"overflow-x: auto; margin-bottom: 20px;\"\u003e\n  \u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; min-width: 300px;\"\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eFitment\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e1990-1994 Chevrolet Blazer\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eEngine \/ Chassis\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e\n\u003cstrong\u003eL05\u003c\/strong\u003e 5.7L V8 \/ \u003cstrong\u003eGMT400\u003c\/strong\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eStock Output\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e210 hp \/ 300 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eReplaces OEM Part #\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e\n\u003cstrong\u003eDPI1520\u003c\/strong\u003e, \u003cstrong\u003eCC1520\u003c\/strong\u003e, \u003cstrong\u003eMC1520\u003c\/strong\u003e, \u003cstrong\u003eEC1520\u003c\/strong\u003e, \u003cstrong\u003eCU1520\u003c\/strong\u003e, \u003cstrong\u003eAE1520\u003c\/strong\u003e, \u003cstrong\u003eDHR1520\u003c\/strong\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1990-1994 Chevrolet Blazer 5.7L V8\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions \u0026amp; Fitment Warnings\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the GMT400 Blazer?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 1990-1994 Chevrolet Blazer equipped with the \u003cstrong\u003eL05\u003c\/strong\u003e 5.7L V8 engine and the factory 34-inch core support.\u003c\/p\u003e\n\n\u003ch4\u003eDo I need to bleed the cooling system after installation?\u003c\/h4\u003e\n\u003cp\u003eYes, thoroughly burping air from the system after installation is required to prevent localized hotspots and ensure accurate thermostat cycling.\u003c\/p\u003e\n\n\u003ch3\u003eThe Chevrolet Durability Standard\u003c\/h3\u003e\n\u003cp\u003eFull-size utility rigs demand thermal components that withstand heavy trailer tongue weights, severe chassis twist, and sustained low-speed crawling.
