Decades of continuous thermal cycling from the \u003cstrong\u003eVortec 4300\u003c\/strong\u003e (both \u003cstrong\u003eLB4\u003c\/strong\u003e and \u003cstrong\u003eL35\u003c\/strong\u003e variants) degrade these plastic tanks, causing brittleness, stress cracks, and sudden separation along the tank crimp lines. Additionally, factory mechanical clutch fans sap usable engine horsepower while failing to draw sufficient CFM at low RPM, precipitating dangerous heat soak during stop-and-go traffic, towing, or trail crawling.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis heavy-duty upgrade utilizes 100% brazed, aircraft-grade aluminum construction with robust, precision TIG-welded end tanks, permanently eliminating crack-prone plastic and bonded seams. The multi-louvered, dual-row tube-and-fin aluminum core significantly increases fluid contact surface area for accelerated thermal dissipation. Paired with a tailored aluminum fan shroud and high-velocity electric cooling fan, the assembly forces air uniformly across the entire core surface area. This configuration drastically lowers coolant discharge temperatures without the parasitic drag of an engine-driven fan.\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; margin-bottom: 20px;\"\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;\"\u003e1992-1994 GMC Jimmy\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;\"\u003e4.3L Vortec 4300 (LB4 \/ L35) \/ GMT330 (S-Series)\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;\"\u003e165-200 hp \/ 235-260 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;\"\u003eN\/A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1992-1994 GMC Jimmy Base 4.3L V6\u003c\/li\u003e\n  \u003cli\u003e1992-1994 GMC Jimmy SLE 4.3L V6\u003c\/li\u003e\n  \u003cli\u003e1992-1994 GMC Jimmy SLS 4.3L V6\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the GMT330 Jimmy?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 1992-1994 GMC Jimmy equipped with the \u003cstrong\u003eVortec 4300\u003c\/strong\u003e engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this assembly eliminate the factory mechanical fan clutch?\u003c\/strong\u003e\u003cbr\u003e Yes, the integrated electric fan and matched shroud replace the OEM engine-driven fan, freeing up rotational horsepower and providing continuous airflow independent of engine speed.\u003c\/p\u003e\n\n\u003ch3\u003eThe GMC Utility Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to handle harsh off-road duty and continuous towing, this cooling module delivers the thermal stability and structural durability demanded by classic GMC truck platforms.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50593926840568,"sku":"DS-ECHYWE4IJ","price":362.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/performance-radiator-with-shroud-for-gmc-jimmy-1992-1994-4-3l-1.jpg?v=1790053055","url":"https:\/\/performancechiptuning.com\/fr\/products\/performance-radiator-with-shroud-for-gmc-jimmy-1992-1994-4-3l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
