34-Inch Core Width Radiator for 1988-1993 Chevy C1500/K1500/Suburban LS/LT Swap
Swapping an LS or LT engine into a 1988-1993 Chevy C1500, K1500 or Suburban with a manual transmission often pushes stock cooling to its limit, and this 34 inch core width radiator is engineered to keep temperatures in check. With a full aluminum core that drops into the factory mounts, it offers a direct fit for GM's GMT400 platform while shedding excess heat during spirited driving or heavy towing. Its robust design and ample cooling surface ensure consistent coolant flow under load, keeping your engine within its optimal temperature range.
Direct Fit for 1988 to 1993 GMT400 Manual Transmission
Designed to slot directly into the factory mounting points of the GMT400 C/K chassis, this 34 inch core radiator requires no modification or trimming. By maintaining stock hose routing and bracket positions, it preserves correct coolant flow while sharply reducing installation time. Whether you are upgrading an LS swap or a later LT application, the seamless integration removes common fitment hurdles. This direct fit approach also retains original fan shroud clearance, ensuring proper airflow without extra adapters.
Precision TIG Welding for Leak Free Performance
Every tank and cooling tube is joined using 100% TIG welding, a process prized for its deep fusion and minimal distortion in aluminum assemblies. Unlike less precise methods, TIG welding creates a consistent bead that virtually eliminates porosity, ensuring a robust seal under constant thermal cycling and vibration. This construction provides uniform strength across the entire shell and maximizes resistance to pressure spikes experienced during hard pulls or heavy towing. The result is a dependable cooling solution that stands up to the rigorous demands of high output engine swaps.
Full Width Aluminum Core Optimizing Heat Rejection
At the heart of this design lies a full width aluminum core that spans 34 inches, delivering an expansive surface area for rapid thermal exchange. The large core volume accelerates coolant circulation and uniformly disperses heat, which is essential when operating under heavy load or in hot ambient conditions. Aluminum's inherent conductivity and lightweight character contribute to swift temperature stabilization, helping maintain ideal engine climate during spirited driving or extended towing. Combined with precise fin density, this radiator design keeps an LS or LT swap firmly within its most efficient temperature range.
Coating Choices for Protection and Aesthetics
Offered in classic bare aluminum or a durable black epoxy finish, this radiator adapts to both functional and visual requirements. The epoxy coating adds a protective barrier against moisture and corrosion, which is especially beneficial for vehicles exposed to salt or humid environments. On the other hand, the bare metal option showcases the raw sheen of the aluminum core and can be polished over time for a custom appearance. Both finishes deliver the same level of cooling performance, so you can choose based on personal style and application needs.
