1988-1993 Chevy C1500/K1500/Suburban Radiator for LS and LT Swaps
Installing an LS or LT powerplant into a 1988 through 1993 Chevy C1500, K1500 or Suburban demands a radiator that fits using the factory mounting points and resists heat buildup under load. By plugging directly into the GMT400 OBS frame rails, this 1988 through 1993 LS Radiator 34 inch Core Width for manual transmissions eliminates cutting or adapter brackets while keeping original hose inlet and outlet locations intact. Crafted using precision TIG welded aluminum tanks and a 34 inch core the assembly forms a seal that resists leaks and stands up to repeated temperature cycles. Cooling performance remains stable during heavy towing or spirited drives so engine temperatures and transmission oil viscosity stay within safe operating limits.
Direct Frame Mount Alignment for 1988 to 1993 GMT400 Trucks
This radiator is engineered to fit precisely into the factory mounting points of 1988 to 1993 Chevy C1500, K1500, and Suburban trucks with a manual transmission, eliminating any need for custom brackets or cutting. By preserving the original hose inlet and outlet positions, it maintains the designed coolant flow path and ensures proper clearance for the fan shroud. Installers benefit from a straightforward process that reduces labor time and minimizes the risk of misrouted hoses or misaligned supports. Retaining the stock mounting geometry also preserves chassis integrity, so the frame rails and crossmembers remain unaltered. The result is a plug-and-play solution that keeps installation efficient and reliable.
Efficient Heat Dissipation via 34 Inch Core
The expansive 34 inch core provides a broad surface area that accelerates coolant throughput and maximizes thermal transfer from high output LS and LT engines. Aluminum's high conductivity draws heat away from the engine block rapidly, preventing hotspots under heavy towing or spirited driving. Even when operating at sustained loads, this full width design ensures coolant temperature remains within safe limits, which safeguards transmission oil stability and extends component life. The wide core also reduces temperature variance across the radiator face, promoting consistent performance across all cooling tubes. Drivers experience improved temperature control in hot weather or during prolonged pulls.
Robust Aluminum Construction with Precision TIG Welding
High quality aluminum tanks and end caps are joined to the core using TIG welding, a method known for creating uniform, low-porosity bonds. This process produces seams that resist cracking under repeated thermal cycling and engine vibration, ensuring a leak free seal over years of service. Combined with aluminum’s natural resistance to corrosion, the assembly delivers a durable yet lightweight package capable of withstanding road shock and temperature swings. Each unit is built in the USA to exacting standards, providing peace of mind for long term reliability. The result is a radiator that resists fatigue and holds tight under the toughest driving conditions.
Protective Coatings for Corrosion Resistance and Style
Choose between a clean bare aluminum finish that highlights the metal’s natural sheen or a black epoxy coating for enhanced protection. The epoxy barrier shields the core and tanks from moisture, road salt, and debris, making it ideal for trucks exposed to winter climates or coastal air. In bare form, the uncoated surface can be polished to a mirror like glow to suit custom engine bays. Both finishes deliver identical cooling efficiency, so appearance choices do not impact performance. This flexibility ensures lasting protection while allowing personalization to match the vehicle’s aesthetic.
