34-inch Core LS and LT Radiator with Fans for 1988-1993 Chevy C1500 K1500 Suburban
If you are swapping an LS or LT engine into a 1988 to 1993 Chevy C1500, K1500 or Suburban manual truck this radiator with a 34 inch core width and dual fans keeps coolant within safe limits under heavy towing or hot ambient conditions. Equipped with a full width aluminum core and dual high output fans it delivers consistent airflow across the entire surface while precision TIG welded tanks resist leaks under vibration and pressure spikes. Installation is straightforward with direct fit mounts for the GMT400 chassis manual models and requires no frame modifications.
Precision TIG Welded High Grade Aluminum Structure
Every seam on the tanks and core is joined by TIG welding, a process known for its precise control and pore free bonds. This method produces a remarkably robust structure that resists vibration and pressure spikes common to heavy towing. By fusing high quality aluminum with pinpoint accuracy, the radiator maintains peak performance without risk of coolant loss. This approach also ensures consistent wall thickness and joint strength across the entire assembly. Manufactured domestically, each unit undergoes rigorous inspection to deliver leak free reliability under sustained workload.
Full Width 34 Inch Aluminum Core Boosts Heat Rejection
At 34 inches across, the full width aluminum core expands both coolant volume and surface area for improved thermal exchange. Extruded coolant passages guide flow uniformly to eliminate hotspots during extended towing or spirited acceleration. The combination of thin wall tubing and dense fin arrays increases heat transfer rate, quickly moving warmth from coolant to air. Aluminum's high conductivity accelerates cooldown cycles, while its light weight helps maintain front end balance on the GMT400 chassis. This design covers the space of the original unit for a direct fit without frame alteration.
Dual Fan Cooling System for Consistent Airflow Management
Featuring two high output fans, the assembly ensures continuous air movement through the core under all operating conditions. An integrated shroud channels airflow evenly across the entire surface, so no section is starved of cooling. The fans activate based on coolant temperature, preventing heat soak in idling traffic or steep climbs. This dynamic response maintains stable engine temperatures whether towing a heavy load or navigating urban streets. Direct fit mounts lock the fan module securely to the GMT400 chassis for manual transmission models, streamlining installation and eliminating the need for aftermarket brackets.
Bare Aluminum and Epoxy Coatings for Corrosion Defense
Installers may choose the natural bare aluminum finish to maximize thermal transfer; the reflective surface also coordinates with engine bay styling. Alternatively, a baked on black epoxy coating forms a tough barrier against moisture, road salt, and debris, extending core life in harsh environments. Both options preserve structural strength and cooling performance, so nothing is sacrificed for protection or visual appeal. This flexibility allows builders to match the radiator to personal preferences while ensuring dependable operation in all climates. Each coating is applied under strict quality controls for lasting service.
