LS and LT Radiator for 1967-1987 C/K Series Chevy GMC Trucks Blazer Suburban
When fitting an LS or LT powerplant into a 1967-1987 C/K Series SquareBody pickup, maintaining stable coolant temperatures under towing or urban traffic proves critical. This 1967-1987 GM Truck Radiator 18.5" Tall (Auto Trans) provides a direct drop in solution that preserves factory inlet and outlet locations and matches the original core height for proper hood clearance. Constructed from corrosion resistant aluminum with precision welded seams and dedicated transmission fittings, its expanded tube and fin core accelerates heat transfer to keep coolant temperatures in check under sustained load or low speed operation. By keeping hose runs tension free and retaining exact mounting tab positions, this radiator reduces installation time and prevents premature hose wear.
Precision Fitment for 1967 to 1987 SquareBody Integration
From C10 to Suburban, the 18.5 inch core height of this radiator matches factory mounting tab positions on 1967 to 1987 SquareBody frames and bodies. Preserving the original inlet and outlet locations allows coolant hoses to remain free of tension, preventing kinks and premature wear without trimming or rerouting. The radiator maintains correct hood clearance to ensure uniform airflow across the core, which is vital for stable engine temperatures under towing or low speed conditions. Installers benefit from a true drop in solution that cuts installation time and eliminates the need for custom brackets or shims. By aligning precisely with factory geometry, this design reduces the risk of leaks and post assembly adjustments to hose runs or fan shrouds.
Premium Aluminum Core for Superior Heat Rejection
Constructed entirely from premium aluminum, the core delivers exceptional thermal conductivity to move heat quickly from coolant into ambient air. An expanded tube and fin arrangement increases the contact surface inside the radiator, which accelerates heat transfer during sustained load or stop and go driving routines. Aluminum's innate resistance to internal corrosion helps preserve coolant flow and system pressure even after years of use. The lightweight nature of aluminum also reduces front end mass, improving steering response and contributing to a balanced drive feel. This combination of rapid heat rejection and durability makes it ideal for LS and LT engine conversions where thermal management is critical.
Coating Selection for Extended Corrosion Protection
Builders can choose a classic bare aluminum finish that showcases the metal's natural appearance or opt for a black epoxy coat for enhanced protection in corrosive environments. The epoxy layer forms a dense protective film that resists road salt, oil stains and small debris impact, extending service intervals and preserving core integrity. Both finishes go through rigorous adhesion and thermal cycle testing to ensure they remain intact through repeated temperature swings and engine vibration. The painted option maintains its protective qualities without hindering heat rejection, while the bare surface allows for visual inspection of core condition over time. This flexibility allows restorers to tailor both appearance and protection to suit daily driving or occasional towing applications.
Engine Cooling Capacity Tailored for LS and LT Powerplants
Designed to meet the higher coolant volume and pressure demands of modern LS and LT engines, this radiator features reinforced weld seams and dedicated transmission fittings for automatic gearboxes. It handles elevated flow rates from high capacity water pumps without risk of heat soak or pressure spikes, ensuring consistent temperature control under towing loads or spirited acceleration. Stable coolant circulation at idle and highway speeds prevents performance-reducing heat spikes and protects engine components from thermal stress. This reliable cooling platform supports advanced powertrain tuning and drivetrain upgrades, allowing enthusiasts to focus on performance gains with confidence. It also enhances resale value by maintaining factory style coolant paths and system reliability.
