1988-1993 Chevy C1500/K1500/Suburban Radiator for LS and LT Engine Swaps
For enthusiasts installing LS or LT powerplants into 1988 to 1993 GMT400 Chevy C1500, K1500 or Suburban trucks, the 1988-1993 LS Radiator 34" Core Width (Manual Trans) with Fans provides a precise cooling solution for demanding swaps. Its 34 inch aluminum core expands coolant volume and works with dual performance fans to manage heat during heavy towing or slow moving traffic. Manufactured in the USA with 100% TIG welded aluminum core and tanks, it resists leaks and corrosion under constant load. Direct bolt on fitment to GMT400 brackets requires no cutting or drilling while finish choices in bare aluminum or black epoxy maintain cooling efficiency and hood style.
Cooling Core Design
The 1988–1993 LS Radiator features a full width 34 inch aluminum core that delivers superior heat transfer capacity. With extra surface area and optimized tube spacing, it dissipates engine heat quickly under sustained load. The 34 inch dimension aligns precisely with factory mounting points in classic chassis, ensuring a seamless fit. By leveraging high grade aluminum, the core remains lightweight while resisting corrosion over time. This design is particularly significant for vehicles equipped with manual transmissions, as it sustains stable fluid temperatures for both engine and gearbox under spirited driving conditions.
Fan System and Build Quality
This radiator arrives with dual high performance fans pre installed, providing balanced airflow across the entire heat exchanger. Each electric fan draws air at low motor speed settings to maintain consistent cooling even at idle. By integrating two fans, hot spots are ironed out, reducing the risk of localized overheating. Construction features TIG welded finish on both tanks and core sections, offering strong seam integrity and superior leak resistance. Every unit is made in the USA, reflecting strict quality control processes from raw material sourcing to final assembly. The result is a durable product built to withstand track day stress or daily drive demands.
Compatibility and Installation
Engineered for LS and LT V engine platforms, this radiator provides direct fitment for popular swap applications. It works in tandem with MuscleRods mounts to ensure correct engine placement and optimal drivetrain angles, preserving alignment across the powertrain. Installation follows factory-style connections for coolant lines and fan power harness, reducing fabrication time. The manual transmission design includes a separate pump feed outlet, accommodating transmission cooling requirements. Technicians and enthusiasts alike appreciate the straightforward install process without compromising on performance or reliability.
