34" Core Radiator with Fans for LS and LT Swaps on 1988-1993 Chevy C1500/K1500/Suburban
Installing a high output LS or LT engine into a 1988-1993 Chevy C1500, K1500, or Suburban with an automatic transmission often exposes cooling weak points. This 34" core radiator with dual fans keeps temperatures in check when towing heavy loads or idling in traffic. It features a full width aluminum core that accelerates heat transfer across the chassis while two calibrated electric fans maintain airflow at low vehicle speeds. With a direct fit design that uses factory mounts on the GMT400 platform and TIG welded tanks finished for corrosion resistance, this radiator delivers lasting performance and straightforward installation for demanding swap builds.
Optimized Aluminum Core for Sustained Heat Rejection
The full width 34 inch aluminum core maximizes the surface area for coolant to air contact, allowing engine heat to transfer quickly into the airflow. Aluminum's natural thermal conductivity ensures rapid dissipation of heat under continuous towing or steep climbs. By spreading warmth evenly across the core, coolant temperatures remain stable even during extended periods of high engine output. This consistency protects internal components from thermal stress and reduces the chance of heat soak in demanding driving scenarios.
Calibrated Dual Fans for Automatic Transmission Cooling
Equipped with two high capacity electric fans, this assembly maintains airflow when vehicle speed is too low for natural cooling. Each fan is tuned to match the thermal load of an automatic transmission setup, so they engage only when extra circulation is needed. This precise activation prevents coolant from warming excessively during slow traffic or heavy duty towing. The result is steady performance of both engine and transmission fluid cooler throughout varied operating conditions.
Precision TIG Welding Boosts Structural Integrity
Every joint between the tanks and core is crafted using TIG welding, a process known for creating uniform, high strength seams. Unlike crimped or brazed connections, TIG welds resist fatigue caused by engine torque and road vibration. Eliminating plastic end tanks also removes a common failure point that can warp under heat. Technicians benefit from a single piece aluminum construction that stays rigid under load and simplifies leak detection in service intervals.
Durable Bare Aluminum and Epoxy Finishes
Installers can choose between the classic bare aluminum look or a sleek black epoxy finish to complement any engine bay design. The epoxy option adds a protective coating that slows corrosion from moisture and road salt, making it ideal for climates with winter treatments on pavements. Even the untreated aluminum surface forms a natural oxide barrier that shields the metal from rust. Both finishes ensure that the radiator remains reliable and visually integrated with LS or LT conversions over years of use.
