1988-1993 Chevy C1500 K1500 Suburban LS and LT Radiator with 34-Inch Core and Fans
This 34 inch radiator with dual high-capacity fans is engineered for LS and LT engine swaps in 1988 to 1993 Chevy C1500, K1500, and Suburban trucks that use an automatic transmission, ensuring consistent cooling when towing or idling in traffic. It features a full width aluminum core that accelerates heat rejection under heavy loads and reduces heat soak on steep grades. Installation drops into factory locations without brackets, so engine cooling integrates precisely into the GMT400 chassis. Built with TIG welded tanks and a corrosion resistant design, this assembly keeps coolant temps in check during demanding driving conditions.
Full Width Aluminum Core Enhances Heat Rejection
The radiator features a full width aluminum core spanning 34 inches across the chassis, which maximizes the surface area available for heat exchange. Aluminum is chosen for its high thermal conductivity, allowing rapid transfer of engine heat to the incoming airflow. This broad core minimizes coolant temperature rises during heavy towing or sustained climbs, reducing the risk of heat soak. The design supports LS and LT swaps by maintaining consistent coolant temperatures even under high load, which safeguards internal engine components and ensures stable performance.
Dual Electric Fans Calibrated for Automatic Transmission Setups
Equipped with two high capacity electric fans, this radiator maintains airflow through the core when vehicle speed drops below optimal levels. These fans are specifically tuned for automatic transmission applications, providing balanced air movement that matches the thermal demands of towing or extended idling. By engaging precisely when needed, the fans prevent coolant temps from spiking during traffic or while towing heavy loads. This regulation of engine temperature contributes to uninterrupted power delivery and avoids stress on the transmission fluid cooler circuit.
TIG Welded Construction for Rigidity and Leak Prevention
Tanks and core are joined using precision TIG welding, a process that yields consistent weld beads with superior strength. Compared to brazed or crimped joints, these welds offer excellent fatigue resistance under constant vibration from the road and engine torque. The all aluminum construction eliminates plastic end tanks, which can warp or crack over time. Technicians benefit from a durable and light weight assembly that resists corrosion at weld seams, reducing the chance of coolant loss and simplifying maintenance.
Bare Aluminum or Black Epoxy Coating for Corrosion Protection
This radiator is available in classic bare aluminum or a black epoxy finish, allowing custom installers to match engine bay aesthetics while boosting durability. The epoxy option adds a protective layer that inhibits oxidation and salt spray damage, which is especially valuable in coastal or winter driving climates. Even the uncoated aluminum surface resists rust by forming a natural oxide barrier that slows further deterioration. Choosing the right finish ensures that the radiator remains both functional and visually integrated with LS or LT swapped GMT400 trucks for years to come.
