1988-1995 C/K Series Chevy C1500/K1500 Tahoe/Suburban Yukon LS and LT Swap Radiator with Fans
When a GMT400 C1500 or Yukon swap overheats under load, the 1988-1995 LS Radiator 28.25" Core Width (Auto Trans) with Fans manages coolant temperatures where the stock system cannot. Featuring an oversized 28.25 inch core and dual electric fans, it delivers consistent airflow across the full core width to prevent hot spots in stop and go traffic or steep grades. TIG welding bonds high grade aluminum tanks and core for leak resistance, while the design requires no chassis modifications on C1500, K1500, Tahoe, Suburban or Yukon models. This lightweight setup sheds front end mass and resists corrosion on the road, ensuring reliable performance during trailer pulls or spirited highway runs.
Enhanced Heat Rejection with Oversized 28.25 Inch Core
The radiator's oversized 28.25 inch core significantly expands the coolant contact area to accelerate the rejection of engine heat during heavy towing or spirited runs. By increasing both the tube length and the fin density across a wider profile, heat energy is spread out and expelled more effectively even in slow traffic or on steep grades. This extra surface area works in tandem with the full width fan coverage to eliminate hotspots that can form at the edges of narrower cores. Designed to bolt directly to GMT400 C1500, K1500, Tahoe, Suburban and Yukon chassis points, the unit requires no cutting or adapter plates for a precise fit. As a result, owners benefit from cooler coolant temperatures and steady performance from coast to coast.
Precision TIG Welded Aluminum for Structural Integrity
TIG welding unites the high grade aluminum tanks and core with uniform, pore free bead formation that delivers superior structural integrity under constant thermal cycling. This process reduces the risk of joint failure and coolant leakage when the engine vibrates or heats rapidly. Aluminum also provides natural resistance to corrosion in road salt and moisture laden environments, while shaving pounds from the front end to improve handling. The robust bond created at each seam means fewer service interventions over the life of the vehicle and more confidence on long excursions. Together these attributes elevate reliability in LS and LT engines that run at higher operating temperatures than factory systems.
Integrated Dual Electric Fans for Consistent Airflow
A matched pair of electric fans is positioned behind the core to maintain uniform airflow across every tube and fin, which helps prevent uneven cooling under demanding conditions. Each fan motor engages at predetermined coolant thresholds to respond instantly to sudden load changes such as trailer pulls or traffic gridlock. Splitting the duty between two smaller units reduces wear on individual motors, lowers noise levels and extends service life compared to a single large fan. The pre wired harness and built in temperature controller simplify the wiring process and eliminate the need for extra relays or switches. This fan assembly delivers reliable thermal management without cluttering the engine bay or requiring time consuming modifications.
Finish Options for Climate and Roadside Defense
Installers may select a classic bare aluminum finish to highlight the metal's natural sheen or opt for a black epoxy coating for enhanced protection in harsh environments. The epoxy layer adheres tightly to the tank and core surfaces to guard against debris impact, salt spray and airborne particulates that can erode metal over time. Coating thickness is controlled to ensure there is no compromise in thermal transfer efficiency, preserving the radiator's ability to shed heat rapidly. This choice of finishes allows a clean presentation under the hood while offering tailored defense based on local climate and road conditions. As a result, the system not only cools effectively but also maintains its appearance and performance in all stages of service.
