1988-93 Chevy C/K Series 34 Inch Core Radiator for LS LT

Supporting serious LS and LT conversions in 1988–93 C/K Series trucks, the 34-inch aluminum core rapidly dissipates heat to maintain stable manual transmission performance under heavy load or high ambient temperatures. Proven direct-fit design with 100% TIG welded tanks and premium aluminum delivers exceptional strength, lasting durability and enhanced resale value.

LS and LT Swap Radiator for 1988-1993 Chevy C/K1500 and Suburban

When installing an LS or LT engine into a 1988-1993 Chevy C/K1500 or Suburban with a manual transmission, the 1988-1993 LS Radiator 34 inch Core Width Manual Trans model addresses rising coolant temperatures to ensure stable engine operation. Engineered to drop straight into factory mounts, it preserves stock hose routing and fan shroud clearance for error free installation. A full aluminum core with precision TIG welds delivers durability under thermal cycling and vibration. Together these features keep your GMT400 chassis swap running cool during spirited driving or heavy towing.

Direct Fit Design for LS LT Swaps on 1988 to 1993 GMT400 C K Series

This radiator is engineered to drop straight into the factory mounts of the GMT400 C K chassis without trimming or modification. By preserving the stock hose routing and bracket positions, it ensures correct coolant flow and maintains original fan shroud clearance for optimal airflow. Swapping in an LS or LT engine often creates tight packaging challenges, and this direct fit design removes guesswork, reducing installation time and potential fitment issues. Whether you're tackling a weekend build or a professional install, the seamless integration into a manual transmission setup streamlines the process.

Precision TIG Welding and Robust Aluminum Construction

Every tank and cooling tube on this radiator is joined with 100 percent TIG welding, a process prized for its deep fusion and minimal distortion in aluminum assemblies. This method creates a uniform bead that virtually eliminates porosity, resulting in a leak-free seal under constant thermal cycling and vibration. Constructed from high-quality aluminum throughout, the assembly offers a sturdy shell that resists pressure spikes during hard pulls or heavy towing. The combination of precision welding and premium material delivers long term reliability in demanding swap applications.

34 Inch Full Width Core for Superior Thermal Efficiency

At the heart of this design lies a 34 inch full width aluminum core that provides an expansive surface area for rapid heat exchange. The increased core volume accelerates coolant circulation and disperses heat evenly, which is critical when running high-output LS or LT engines under load. Aluminum's natural thermal conductivity and lightweight character help stabilize temperatures quickly, preventing hot spots during spirited drives or extended towing sessions. This generous core dimension keeps the engine within its ideal operating range, enhancing performance and longevity.

Bare Aluminum and Epoxy Coating Options for Protection

Choose between the raw sheen of bare aluminum or a tough black epoxy finish based on your application needs. The epoxy coat adds a barrier against moisture and corrosion, suited for vehicles exposed to road salt or humid climates. In contrast, the bare metal option highlights the bright aluminum and can be polished over time to achieve a custom look. Both finishes deliver identical cooling performance, so you can balance aesthetic preference with environmental protection without sacrificing efficiency.

This radiator is ready to maintain steady temperatures in your LS LT swap project. For the same radiator but with fans see our 1988-1993 LS Radiator 34" Core Width (Manual Transmission) with Fans.
