1988-1995 C/K Series GMT400 LS/LT Radiator 28.25 inch Core Manual Trans with Fans
Swapping an LS or LT motor into a 1988 to 1995 C/K Series GMT400 truck demands precise coolant control and this radiator with a 28.25 inch core and dual fans delivers consistent temperature regulation under heavy load. It installs using original frame mounts on manual transmission models so no cuts or custom brackets are required. Featuring precision TIG welded aluminum tanks and an extra wide fin stack this design accelerates heat rejection at idle traffic and during towing. The electric fans activate automatically as coolant temperature rises to ensure steady airflow in stop and go conditions.
Precision TIG Welding for Aluminum Durability
The radiator's tanks and core are joined using precision TIG welded seams to create exceptionally uniform joints. This method produces clean weld beads that resist the pressure fluctuations and temperature swings common in towing and hard acceleration. By eliminating micro gaps, the assembly offers reliable leak prevention and withstands repeated thermal cycles without fatigue. Installers benefit from a plug-and-play unit that drops into the original frame mounts on manual transmission models, eliminating the need for extra support brackets or trimming. Fabricated domestically with high-quality aluminum, this radiator upholds strict quality standards for long service life.
Extra Wide 28.25 Inch Core for Rapid Heat Transfer
Featuring a full 28.25 inch core width, this radiator maximizes surface area to accelerate coolant cooling under sustained load. The expanded fin stack and broad coolant channels draw heat away from the engine more efficiently, helping to prevent temperature spikes during uphill climbs or prolonged towing. This added capacity reduces stress on hoses and seals by maintaining stable fluid temperatures even in hot weather or traffic jams. Engineers designed the core thickness to balance coolant volume with airflow resistance, ensuring smooth circulation. The result is consistent thermal control that safeguards internal engine components and improves overall swap reliability.
Automatic Dual Fan Airflow Management
Preinstalled dual fans ensure continuous airflow through the core as soon as coolant temperature rises, eliminating airflow loss at idle or in stop-and-go scenarios. Each fan is calibrated to activate automatically, helping the truck maintain optimal operating temperature whether creeping through city streets or cruising on the highway. The fans mount directly to factory locations, so no custom brackets or frame mods are necessary. A plug and play wiring harness streamlines the electrical hookup and prevents wiring errors that can occur with aftermarket adapters. This design delivers consistent ventilation at low vehicle speeds where heat rejection is most critical.
Choice of Bare Aluminum or Epoxy Coating for Corrosion Control
Owners can select the natural finish of bare aluminum or opt for a black epoxy coating that adds an extra barrier against moisture and road salt. The epoxy layer is applied under controlled temperature conditions to ensure uniform coverage and strong adhesion that resists chipping or peeling. Bare aluminum preserves the metal's innate resistance to oxidation while showcasing the precise weld beads and fin architecture. Choosing the epoxy finish provides a robust corrosion barrier ideal for harsh climates or frequent off-road use. Both options deliver long-lasting protection without compromising the radiator's thermal performance.
