LS and LT Radiator for 1988-1993 Chevy C1500 K1500 Suburban
When you swap an LS or LT motor into a 1988 to 1993 Chevy C1500, K1500 or Suburban manual truck your stock cooling often falls short under heavy load and hot weather conditions. This 34 inch core radiator with dual fans keeps coolant temperatures stable during towing, off road runs and stop and go driving by supplying consistent airflow across the full width aluminum core. Built around precision TIG welded tanks and core the design ensures leak free operation under vibration and pressure spikes common to GMT400 C K pickups. Installation is straightforward thanks to direct fit mounts crafted for manual transmission C1500, K1500 and Suburban models and eliminates the need for frame alterations.
Expanded 34 Inch Aluminum Core Design
The 34 inch aluminum core delivers a significant boost in cooling capacity by enlarging both coolant volume and surface area. Extruded coolant passages ensure uniform flow across the entire width, eliminating hotspots during heavy towing or spirited acceleration. By maximizing the interface between the coolant and the fin array, it speeds up heat rejection and stabilizes engine temperature under sustained load. The light weight of aluminum helps maintain front end balance on GMT400 trucks, while the full width design covers the space previously occupied by the stock unit. This precise fitment also removes the need for frame modifications in 1988 to 1993 C1500, K1500 and Suburban manual models.
Dual Fan System for Consistent Airflow
Equipped with two high output fans, the assembly delivers continuous airflow in stop and go traffic and off road scenarios. The fan module monitors coolant temperature and engages each fan as needed to prevent heat soak when the truck is idling or climbing steep grades. A custom shroud channels air evenly across the core face, ensuring no section is starved of cooling. This configuration keeps temperatures within optimal range whether cruising the highway or crawling through urban streets. Direct fit mounts for manual transmission GMT400 chassis make installation straightforward and secure.
TIG Welded Assembly for Leak Free Durability
All seams and joints on the tanks and core are joined with precision TIG welding, a method renowned for producing virtually pore free bonds. This welding style creates a strong, resilient structure that endures vibration and pressure spikes common in heavy duty use. Combined with premium grade aluminum, the result is a radiator built to withstand the rigors of towing, desert runs, and daily commuting alike. Every unit is manufactured in the USA under strict quality controls to guarantee lasting reliability. This robust construction also reduces the risk of coolant loss and unplanned downtime.
Coating Options for Corrosion Defense and Style
Installers can choose a classic bare aluminum finish to maximize thermal transfer or opt for the black epoxy coating for enhanced corrosion resistance and under hood appearance. The epoxy is baked on to form a tough barrier against moisture, road salt, and debris, helping preserve core integrity over time. Both finishes maintain the radiator's structural strength and cooling performance, so nothing is sacrificed for protection or looks. This flexibility allows builders to match the radiator to personal preferences or vehicle color schemes while ensuring dependable operation in all climates.
