LS and LT Radiator for 1988-1993 Chevy C1500/K1500/Suburban
For LS or LT engine swaps in your 1988-1993 Chevy C1500, K1500, or Suburban this radiator provides reliable heat dissipation under heavy load and city traffic. Its 34-inch aluminum core width and dual electric fans are optimized for automatic transmission setups, offering consistent airflow and preventing overheating during towing or spirited driving. Installation aligns with factory mounting points to simplify setup on the GMT400 chassis. By stabilizing coolant temperature you protect internal components and maintain steady power delivery every mile.
Full Width Aluminum Core for Optimal Heat Rejection
The 34 inch full width aluminum core delivers a vast surface area that accelerates heat transfer from coolant to air. This design leverages aluminum's high thermal conductivity to reject heat quickly, keeping LS and LT engines running at ideal temperatures under heavy loads. By maximizing the core's width, the radiator maintains lower coolant temperatures during towing, hill climbs, or track sessions, reducing the risk of heat soak and enhancing engine longevity.
Dual Electric Fans Ensuring Steady Airflow
Equipped with two powerful electric fans, this radiator sustains consistent airflow across the core even when vehicle speed is low. The fans are calibrated for automatic transmission setups, pulling cool air through the core to prevent temperature spikes in stop-and-go traffic or while idling on hot days. Their combined airflow capacity helps stabilize engine temperature and supports reliable power delivery from city streets to off-road excursions.
Precision TIG Welded Aluminum for Strength and Corrosion Resistance
Every tank and core joint is crafted with 100 percent TIG welding, producing smooth, uniform weld beads that resist fatigue and leaks under vibration. Constructed entirely from premium aluminum, the radiator combines low weight with exceptional structural integrity. The all-metal assembly resists corrosion without internal plastic components, resulting in a maintenance-friendly system built in the USA for proven fit and finish.
Backed by precision TIG welding and full width cooling efficiency, this radiator stands up to demanding LS/LT swaps. For the same radiator but without fans, consider our 1988-1993 LS Radiator 34" Core Width (Automatic Transmission).
