LS and LT Radiator for 1988-1995 Chevy C/K Series Trucks and SUVs
Many enthusiasts planning an LS or LT engine swap into a C/K Series GMT400 truck or SUV need coolant management. The 1988 to 1995 LS Radiator with a 28.25 inch core width on manual transmission vehicles provides precise temperature control under load. It features dual fans installed for automatic airflow and a 100% TIG welded aluminum core and tank assembly to ensure leak free operation. Designed for Chevrolet C1500, K1500, Tahoe, Suburban and GMC Yukon (1988 to 1995) on original frame mounts and installs without custom brackets. Choose bare aluminum or black epoxy finish to protect against corrosion in driving conditions. Precision welding delivers uniform joints and durability.
Comprehensive Cooling Package
The 1988 through 1995 LS Radiator delivers a substantial increase in heat rejection thanks to its oversized 28.25Inch ExtraWide core. By boosting both tube count and fin density this core holds more coolant and exposes a larger surface area for heat transfer. Under heavy acceleration or extended idling the added volume slows the rise in coolant temperature and delays boiling. Two factory installed fans operate in unison to push air through the dense fin pack at low vehicle speeds. Each unit is calibrated for static pressure to eliminate hot spots in stop and go traffic. Together these elements ensure that LS and LT engines maintain safe operating temperatures during spirited street driving or long highway runs.
Precision Metalwork and Durability
All tanks and core panels are crafted from high grade aluminum and sealed with 100 percent TIG welded joints. The precise arc control of the TIG process forms uniform beads that prevent voids and resist stress cracking through repeated thermal cycles. After assembly each radiator undergoes pressure and vibration tests to certify leak free performance under demanding conditions. The all aluminum construction offers superior corrosion resistance compared to mixed metal systems and maintains consistent conductivity for rapid thermal transfer. Built in the USA under strict quality standards this radiator ships with a bare aluminum finish and has been leak checked at the factory. High-performance fans complement the core design by drawing minimal current while delivering peak airflow exactly when it is needed.
Seamless Engine Fit and Drivetrain Alignment
Specifically engineered for manual trans applications on 1988 to 1995 GM frames running LS or LT platforms this radiator integrates directly with MuscleRods mount systems to ensure correct engine placement and optimal drivetrain angles. Proper tilt of the core maintains straight hose runs to the water pump and prevents unwanted kinks. Mounting points match the original sheet metal plenum so no additional brackets or trimming are required. The fan shroud clears crossmembers and steering linkages for an unobstructed fit. Quick connect hose fittings and a prewired relay harness reduce installation time. Detailed instructions include torque specifications and coolant capacity figures so both professional shops and home builders can complete the conversion with confidence.
