1988-1995 Chevy C/K Series and Tahoe/Suburban/Yukon LS and LT Radiator
Installing LS or LT powerplants in GMT400 trucks often pushes coolant systems to their limit. This 1988-1995 LS Radiator 28.25" Core Width (Auto Trans) with Fans steps in to maintain stable engine temperatures under towing, spirited driving, and stop and go traffic. Constructed from TIG welded aluminum, it resists corrosion, shaves weight compared with the stock unit, and connects directly to factory automatic transmission lines without modifications. Twin electric fans engage at precise thermal thresholds and channel airflow across the full core width for consistent temperature control under demanding conditions.
Exceptional Core Design for Maximum Cooling Efficiency
The 28.25 inch core width significantly boosts the internal surface area in contact with coolant, accelerating the transfer of heat from the engine block to the cooling fins. During heavy towing or spirited driving, the extended flow path prevents coolant temperatures from spiking by allowing more time for heat rejection before fluid returns to the engine. This larger volume also minimizes the risk of heat soak in slow traffic or long highway pulls, maintaining temperature stability under continuous load. Designed to align with the factory mount points on GMT400 chassis, the core installs without modification and delivers greater thermal capacity than the original unit. The overall result is consistent cooling performance that supports both daily driving and demanding duty cycles.
Precision TIG Welding Delivers Leak Resistance and Strength
Every joint on the aluminum core and tanks is produced using a welding process renowned for forming dense, pore free bonds that resist coolant and transmission fluid leaks. By eliminating weak links the radiator maintains integrity under engine vibration and repeated thermal cycling, reducing the chance of failure over time. Aluminum construction cuts significant weight compared with steel alternatives, easing load on front suspension and helping with throttle response. This material also offers inherent corrosion resistance even in harsh road salt or coastal environments. Made in the USA under strict quality standards, the assembly meets rigorous durability requirements for long service life.
Dual Fan Configuration Ensures Even Airflow Distribution
A matched pair of electric fans is installed to deliver uniform airflow across the full width of the core, preventing hot spots that can lead to uneven cooling. Each fan is calibrated to activate at specific coolant temperatures, providing rapid response to sudden load changes such as towing a trailer or accelerating hard on the highway. The dual arrangement reduces strain on each motor compared with a single large fan and extends system longevity. A preinstalled wiring harness and fan controller simplify integration and ensure reliable operation without additional components. Together these elements maintain steady engine temperatures whether idling in traffic or cruising at speed.
Protective Coating Options for Corrosion Defense and Appearance
Installers can choose a bare aluminum finish to showcase the metal's natural look or select a black epoxy coating for extra protection and a modern appearance under the hood. The epoxy bonds tightly to the surface and shields the assembly from road debris, salt spray, and other contaminants that can trigger oxidation. Both finishes are applied with precision to preserve the radiator's thermal transfer characteristics, ensuring that coating does not impede cooling efficiency. In coastal or winter climates the epoxy option maintains its finish without flaking or fading. These choices allow customization of engine bay aesthetics while delivering durable defense against environmental wear.
