Under sustained load—such as heavy towing, plowing, or low-speed crawling—the stock configuration fails to shed heat rapidly. This leads to severe heat soak, elevated coolant temperatures, and increased system pressure that commonly causes the OE plastic tanks to fatigue, leak, and crack at the crimp seams. Furthermore, the factory mechanical clutch fan robs parasitic horsepower from the engine and struggles to pull adequate CFM at low engine RPMs.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis high-performance package eliminates the plastic end tanks in favor of fully TIG-welded, aviation-grade AA5052 aluminum construction. The 3-row core features a dense tube-and-fin design, drastically increasing fluid capacity and maximizing heat exchange surface area for a 35% to 45% thermal efficiency boost. To optimize airflow dynamics, this kit replaces the parasitic mechanical fan with an aluminum shroud housing dual 12-inch electric slim fans delivering a combined 1,600 CFM. Regulated by a precise 180°F-on \/ 165°F-off thermostat relay system threaded directly into the manifold or water neck, it guarantees consistent airflow at all vehicle speeds while reducing engine drag. The 1.25-inch inlet and 1.55-inch outlet ensure restriction-free fluid routing.\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;\"\u003e1988-1999 Chevrolet, GMC C\/K Trucks \u0026amp; Suburbans\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;\"\u003eSBC (L03, L05, L30, L31) \/ GMT400\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;\"\u003e170-255 hp \/ 255-330 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;\"\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\u003e1988-1999 Chevrolet C1500 5.0L\u003c\/li\u003e\n  \u003cli\u003e1988-1999 Chevrolet C1500 5.7L\u003c\/li\u003e\n  \u003cli\u003e1988-1999 Chevrolet C2500 5.0L\u003c\/li\u003e\n  \u003cli\u003e1988-1999 Chevrolet C2500 5.7L\u003c\/li\u003e\n  \u003cli\u003e1988-1994 Chevrolet C3500 5.7L\u003c\/li\u003e\n  \u003cli\u003e1988-1999 Chevrolet K1500 5.0L\u003c\/li\u003e\n  \u003cli\u003e1988-1999 Chevrolet K1500 5.7L\u003c\/li\u003e\n  \u003cli\u003e1988-1999 Chevrolet K2500 5.0L\u003c\/li\u003e\n  \u003cli\u003e1988-1999 Chevrolet K2500 5.7L\u003c\/li\u003e\n  \u003cli\u003e1988-1994 Chevrolet K3500 5.7L\u003c\/li\u003e\n  \u003cli\u003e1988-1999 GMC C1500 5.0L\u003c\/li\u003e\n  \u003cli\u003e1988-1999 GMC C1500 5.7L\u003c\/li\u003e\n  \u003cli\u003e1988-1999 GMC C2500 5.7L\u003c\/li\u003e\n  \u003cli\u003e1988-1999 GMC C2500 5.0L\u003c\/li\u003e\n  \u003cli\u003e1988-1994 GMC C3500 5.7L\u003c\/li\u003e\n  \u003cli\u003e1988-1999 GMC K1500 5.0L\u003c\/li\u003e\n  \u003cli\u003e1988-1999 GMC K1500 5.7L\u003c\/li\u003e\n  \u003cli\u003e1988-1999 GMC K2500 5.7L\u003c\/li\u003e\n  \u003cli\u003e1988-1999 GMC K2500 5.0L\u003c\/li\u003e\n  \u003cli\u003e1988-1994 GMC K3500 5.7L\u003c\/li\u003e\n  \u003cli\u003e1992-1993 Chevrolet C1500 Suburban 5.7L\u003c\/li\u003e\n  \u003cli\u003e1992-1993 Chevrolet C2500 Suburban 5.7L\u003c\/li\u003e\n  \u003cli\u003e1992-1993 Chevrolet K1500 Suburban 5.7L\u003c\/li\u003e\n  \u003cli\u003e1992-1993 Chevrolet K2500 Suburban 5.7L\u003c\/li\u003e\n  \u003cli\u003e1992-1993 GMC C1500 Suburban 5.7L\u003c\/li\u003e\n  \u003cli\u003e1992-1993 GMC C2500 Suburban 5.7L\u003c\/li\u003e\n  \u003cli\u003e1992-1993 GMC K1500 Suburban 5.7L\u003c\/li\u003e\n  \u003cli\u003e1992-1993 GMC K2500 Suburban 5.7L\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Chevrolet, GMC Heavy-Duty Standard\u003c\/h3\u003e\n\u003cp\u003eWhether you are hauling a loaded trailer up steep grades, navigating demanding off-road trails, or daily driving your classic OBS rig, maintaining optimal operating temperatures is critical.

The original brazed joints degrade, leading to microscopic leaks and pressure loss. Furthermore, the inherent thermal inefficiency of the old-school OEM brass cores leads to localized heat soak, especially in the Small Block Chevrolet (SBC) 5.0L and 5.7L engines under sustained load. When subjected to stop-and-go traffic or hauling heavy loads, the factory mechanical clutch fan struggles to pull sufficient CFM at low RPMs, causing dangerous temperature spikes that can warp cylinder heads, compromise gaskets, and degrade transmission fluid.\u003c\/p\u003e\n  \n  \u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n  \u003cp\u003eThis engineered upgrade completely modernizes your Square Body's thermal management.

Paired with an integrated aluminum shroud, the twin 12-inch electric fans deliver a constant 1600 CFM of targeted airflow directly across the fins, completely independent of engine RPM. The included precision thermostatic relay kit automates the entire cooling cycle—activating the fans at 180°F and shutting them down at 165°F—ensuring optimal, stable operating temperatures. It also features a CNC-machined filler neck, an OEM-style brass petcock drain, and an integrated transmission fluid cooler to protect your drivetrain during heavy towing operations.\u003c\/p\u003e\n

\u003ch3\u003eThe Stock 1st Gen C\/K Truck Cooling Weakness\u003c\/h3\u003e\n  \u003cp\u003eFactory copper-brass radiators in early first-generation C\/K trucks and classic GM platforms were adequate for their era, but they suffer from severe thermal limitations when subjected to modern traffic conditions, towing loads, or upgraded horsepower outputs. Over decades of heat cycling, the narrow tube diameters and dense fin pitch become compromised by internal scale buildup, leading to poor coolant flow and systemic heat soak. Furthermore, the OEM engine-driven mechanical fan continuously robs horsepower via parasitic drag and fails to pull sufficient cubic feet per minute (CFM) of air through the core during low-speed crawling or idle, frequently resulting in coolant boil-over and the risk of warped cylinder heads.\u003c\/p\u003e\n  \n  \u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n  \u003cp\u003eThis direct-fit replacement is engineered from full AA5052 aircraft-grade aluminum, maximizing thermal dissipation by utilizing a robust 3-row core design measuring 1.73 inches thick. By drastically increasing fluid capacity and employing optimized louvered fins, it delivers a proven 35% to 45% increase in cooling efficiency compared to OEM stock units. The package includes a custom-fitted aluminum fan shroud mated to a low-profile 16.82-inch 12V electric fan (1000 CFM), permanently eliminating the mechanical fan's parasitic loss while guaranteeing continuous, high-velocity airflow regardless of engine RPM. Regulated by the included 180°F-on \/ 165°F-off thermostatic relay kit, the system maintains a highly stable operating temperature window. This ensures consistent engine performance and longevity, whether idling in dead-stop traffic or hauling heavy loads. The unit also features a built-in 1\/4 NPT transmission cooler for automatic gearbox applications.\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;\"\u003e1963-1966 Chevrolet, GMC C\/K Trucks \u0026amp; Classic GM B\/A-Bodies\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;\"\u003eSBC V8, Pontiac V8, Olds V8, GM Inline-6 \/ 1st Gen C\/K Chassis\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;\"\u003e140 - 320 hp \/ 220 - 355 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;\"\u003eN\/A\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eCore Dimensions\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e17.40\" x 22.76\" x 1.73\" (442 x 578 x 44 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eFan CFM \u0026amp; Draw\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e1000 CFM \/ ≤11 Amps (16.82\" Diameter)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n \n  \u003ch3\u003eCompatibility\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003e1963-1966 Chevrolet C10 C20 C30 Panel 3.8L 4.1L\u003c\/li\u003e\n    \u003cli\u003e1963-1966 Chevrolet C10 C20 C30 Pickup 3.8L 4.1L 4.6L 4.8L 5.3L\u003c\/li\u003e\n    \u003cli\u003e1963-1966 Chevrolet K10 K20 Pickup 3.8L 4.1L 4.6L 4.8L 5.3L\u003c\/li\u003e\n    \u003cli\u003e1963-1966 Chevrolet Suburban 3.8L 4.6L 4.8L\u003c\/li\u003e\n    \u003cli\u003e1963-1966 GMC 1000 1500 2500 Suburban L6 V8\u003c\/li\u003e\n    \u003cli\u003e1965-1966 Oldsmobile Cutlass 5.4L 6.6L\u003c\/li\u003e\n    \u003cli\u003e1964-1965 Oldsmobile F85 3.7L 5.4L 6.6L\u003c\/li\u003e\n    \u003cli\u003e1961-1966 Pontiac Catalina Bonneville 6.4L 6.9L\u003c\/li\u003e\n    \u003cli\u003e1962-1964 Pontiac Grand Prix Star Chief 6.4L 6.9L\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eThe Chevrolet\/GMC Towing Caliber\u003c\/h3\u003e\n  \u003cp\u003eEngineered for rigorous duty cycles, this 3-row aluminum cooling setup delivers the heavy-duty thermal management required to keep classic GM trucks and muscle cars operating safely under high-torque towing demands or extended idle conditions.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":48206250148088,"sku":"DS-ES5LDHC6X","price":234.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/high-performance-radiator-for-chevy-gmc-c-k-1500-2500-3500-pickup-suburban-1963-1966-3-0l-3-8l-5-0l-5-7l-1.webp?v=1775678284"},{"product_id":"high-performance-radiator-for-chevy-s10-blazer-gmc-jimmy-sonoma-1986-2005-4-2l-4-3l","title":"High Performance Radiator for Chevy S10 Blazer GMC Jimmy Sonoma (1986-2005) 4.2L 4.3L","description":"\u003ch2\u003eHigh-Capacity Aluminum Radiator for 1986-2005 Chevrolet, GMC S-10, Sonoma, Jimmy, Blazer (Vortec 4.3L \/ GMT330)\u003c\/h2\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat it is for:\u003c\/strong\u003e This 3-row aluminum radiator and dual-fan shroud kit directly replaces the restrictive factory cooling system to lower operating temperatures by 35% to 45% during heavy towing or aggressive driving.\u003c\/p\u003e\n\n\u003ch3\u003eThe Stock GMT330 Thermal Limitations\u003c\/h3\u003e\n\u003cp\u003eThe OEM plastic-tank and single-core radiators on the GMT330 platform are notorious for severe heat soak, especially when under load, towing, or dealing with the restricted airflow of the S-10 and Blazer engine bays.

\u003cp\u003eThe factory rubber radiator hoses on the 2001-2005 6.6L Duramax platforms are notoriously prone to premature degradation. Exposure to thousands of thermal cycles, engine bay heat soak, and continuous pressure fluctuations causes the OEM EPDM rubber to harden, dry rot, and ultimately crack. Furthermore, under heavy towing loads or aggressive acceleration, the suction created by the water pump can cause an aging, softened lower rubber hose to collapse entirely. This immediate restriction in coolant flow spikes engine operating temperatures and leads to severe overheating conditions, potentially risking head gasket integrity on the LB7 and LLY powerplants.\u003c\/p\u003e\n  \n  \u003ch3\u003eThe Silicone Engineering Solution\u003c\/h3\u003e\n  \u003cp\u003eThis heavy-duty upper and lower radiator hose kit is manufactured from multi-ply, high-temperature reinforced silicone designed to withstand the extreme thermal environment of the Duramax engine bay. Unlike standard rubber, the silicone construction maintains its structural integrity and flexibility across a vastly broader temperature spectrum, boasting a maximum temperature rating of 350°F. The internal reinforcement layers provide exceptional burst pressure resistance, completely eliminating the risk of lower hose collapse under high-RPM water pump suction. By upgrading to these precisely molded silicone lines, mechanics ensure a reliable, leak-free seal that maintains stringent OEM fitment while vastly exceeding factory specifications for thermal degradation and sustained coolant pressure during demanding applications.\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;\"\u003e2001-2005 Chevrolet Silverado, GMC Sierra 2500 \/ 3500\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;\"\u003e6.6L Duramax V8 (LB7 \/ LLY) \/ GMT800\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;\"\u003e300-310 hp \/ 520-590 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;\"\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\u003e2001 Chevrolet Silverado 2500 \/ 3500 6.6L Duramax\u003c\/li\u003e\n    \u003cli\u003e2002 Chevrolet Silverado 2500 \/ 3500 6.6L Duramax\u003c\/li\u003e\n    \u003cli\u003e2003 Chevrolet Silverado 2500 \/ 3500 6.6L Duramax\u003c\/li\u003e\n    \u003cli\u003e2004 Chevrolet Silverado 2500 \/ 3500 6.6L Duramax\u003c\/li\u003e\n    \u003cli\u003e2005 Chevrolet Silverado 2500 \/ 3500 6.6L Duramax\u003c\/li\u003e\n    \u003cli\u003e2001 GMC Sierra 2500 \/ 3500 6.6L Duramax\u003c\/li\u003e\n    \u003cli\u003e2002 GMC Sierra 2500 \/ 3500 6.6L Duramax\u003c\/li\u003e\n    \u003cli\u003e2003 GMC Sierra 2500 \/ 3500 6.6L Duramax\u003c\/li\u003e\n    \u003cli\u003e2004 GMC Sierra 2500 \/ 3500 6.6L Duramax\u003c\/li\u003e\n    \u003cli\u003e2005 GMC Sierra 2500 \/ 3500 6.6L Duramax\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eThe Heavy-Duty Towing Standard\u003c\/h3\u003e\n  \u003cp\u003eWhen hauling heavy payloads or navigating steep inclines, cooling system reliability is non-negotiable.

The stock plastic end tanks degrade rapidly over decades of thermal cycling, causing hairline cracks and debilitating pressure leaks. Furthermore, the OEM single or dual-row core design lacks the adequate fluid volume and surface area required to effectively dissipate heat from the SBC Gen I engines, especially when the vehicle is burdened with heavy payloads, towing on steep inclines, or navigating slow-moving traffic in high-ambient temperatures.\u003c\/p\u003e\n  \n  \u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n  \u003cp\u003eThis heavy-duty, 3-row, all-aluminum performance radiator rectifies these OEM shortcomings by introducing a high-capacity architecture. Constructed from premium TIG-welded aluminum, it completely eliminates the failure-prone plastic end tanks, substituting them with fully welded structural tanks for superior integrity and pressure retention. The robust 3-row core design (20.87\" W x 17.24\" H x 1.65\" T) drastically increases internal coolant volume and maximizes the fin surface area exposed to incoming airflow. This engineered airflow dynamic significantly accelerates thermal exchange, providing an estimated 30% increase in cooling capacity over the standard OEM unit. Designed for both automatic and manual transmissions, this unit ensures your classic GMT400 maintains optimal operating temperatures, preventing critical engine damage from overheating. \u003cem\u003eCritical Fitment Note: Ensure your factory core length is 530mm, not 720mm, prior to installation.\u003c\/em\u003e\u003c\/p\u003e\n  \n  \u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n  \u003ctable width=\"100%\" style=\"border-collapse: collapse;

Furthermore, the OEM core lacks the required fluid capacity and surface area to efficiently dissipate heat from the high-compression L83 or L86 V8 engines, leading to rapid heat soak.

The OEM plastic end tanks are prone to heat cycling fatigue, leading to micro-fractures and inevitable coolant leaks at the crimped seams. Furthermore, the standard core density limits thermal transfer. When the 5.3L L84 or 6.2L L87 V8 engines are pushed hard, the stock system suffers from rapid heat soak, causing the ECM to pull timing to protect the engine block.

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"},{"product_id":"performance-radiator-with-shroud-for-gmc-c-k-trucks-1975-1978-4-1l-4-8l-5-0l-5-7l","title":"Performance Radiator with Shroud for GMC C\/K Trucks (1975-1978) 4.1L 4.8L 5.0L 5.7L","description":"\u003ch2\u003eHigh-Efficiency Aluminum Performance Radiator with Shroud for 1975-1978 GMC C\/K Trucks\u003c\/h2\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat it Does:\u003c\/strong\u003e The All-Aluminum Performance Radiator with Shroud replaces the failure-prone factory cooling assembly on 1975-1978 GMC C\/K Trucks to lower operating temperatures and eliminate boilover under heavy load.\u003c\/p\u003e\n\n\u003ch3\u003eThe Stock GMC C\/K Trucks Cooling Deficiencies\u003c\/h3\u003e\n\u003cp\u003eFactory cooling systems on 1970s \u003cstrong\u003eSquarebody GMC C\/K Trucks\u003c\/strong\u003e rely on aged copper-brass cores and mechanical clutch fans that struggle against modern heat demands. Over decades of heat cycling, factory brazed tank seams suffer fatigue cracking, internal passages succumb to mineral scale occlusion, and solder bloom severely impedes thermal transfer.
