1988-1993 Chevy C1500/K1500/Suburban LS and LT Radiator with 34in Core Width and Fans
Addressing the cooling gaps encountered during LS or LT swaps in 1988 to 1993 Chevy C1500, K1500, and Suburban models, this radiator brings a robust combination of capacity and airflow control. Featuring a 34 inch core of full width aluminum and dual electric fans, it leverages factory mount points on the GMT400 chassis for direct fitment that preserves engine bay clearance. Engineers selected TIG welded tanks treated for corrosion resistance and configured fans to engage only when transmission fluid or coolant temperatures rise during towing or stop and go driving, sustaining steady thermal management for both engine and transmission components.
Full Width 34 Inch Aluminum Core for Superior Heat Dissipation
The expansive 34 inch aluminum core provides an enlarged surface area where hot coolant meets incoming air, speeding heat rejection during heavy towing or steep climbs. Aluminum's innate thermal conductivity allows warmth to spread evenly across the entire core, preventing localized hot spots that can lead to coolant breakdown. This consistency maintains stable engine temperature under continuous load, shielding critical components from thermal stress. By retaining factory mount geometry on the GMT400 chassis, the design also ensures proper fitment and clearance without modifying the engine bay.
Dual Electric Fans Tailored for Automatic Transmission Thermal Control
Two high capacity electric fans are precisely calibrated to engage when either coolant or transmission fluid temperatures exceed safe limits at low vehicle speeds. This targeted activation preserves steady airflow in stop and go traffic or when hauling heavy payloads, reducing the risk of heat soak in the transmission fluid cooler. The fans plug into existing wiring harnesses on the GMT400 platform, simplifying installation and removing guesswork in fan control. Overall, the system balances airflow and electrical draw to keep both engine and transmission operating within optimal temperature ranges.
TIG Welded Aluminum Construction for Enduring Rigidity
Each joint between the core and tanks is formed with TIG welds that produce uniform, high strength seams free of filler distortions common in brazing or crimping. This all-aluminum assembly resists fatigue from engine vibration and road shock, offering greater reliability than plastic-tank alternatives that can warp or crack under heat. Service technicians benefit from a solid metal structure that is easier to inspect for leaks and holds alignment under torque loads. The one-piece design also reduces part count, streamlining maintenance intervals for swap installations.
Coating Choices Enhancing Durability and Aesthetic Appeal
Customers can select either the raw aluminum finish or a protective black epoxy coating to match engine bay themes while guarding against corrosion. The bare surface develops a thin oxide layer that inhibits rust, making it suitable for all climates. The black epoxy option adds an extra barrier against moisture and road salt, extending component life in coastal or winter-treated areas. Both finishes are applied under strict quality standards to ensure even coverage and long-lasting protection without altering the radiator's thermal performance.
