LS and LT Radiator for 1988-1995 Chevy C1500/K1500 Tahoe/Suburban and GMC Yukon
When you install an LS or LT powerplant in a 1988-1995 Chevy C1500, K1500, Tahoe, Suburban or GMC Yukon chassis the 1988-1995 LS Radiator tackles the critical need for stable coolant temperatures under heavy load. By combining a 28.25 inch core width with a pair of fans it channels increased airflow to prevent heat soak during towing or spirited street driving. Constructed from TIG welded aluminum tanks and core it resists corrosion cuts weight compared with the original radiator and connects directly to factory automatic transmission fittings with no modifications required.
Oversized 28.25 Inch Core Maximizes Heat Rejection
The extra width of the 28.25 inch core significantly boosts surface area in contact with coolant, accelerating heat transfer from the engine block to the fins. Under heavy towing or spirited driving, this larger core volume prevents coolant temperatures from spiking by extending the flow path length. It also reduces the chance of heat soak during low speed operation or highway pulls, keeping LS and LT powerplants in their optimal temperature window. By shedding heat more rapidly than stock radiators, it supports sustained performance on both the street and track.
Precision TIG Welded Aluminum Structure Resists Corrosion
Every joint on this radiator is crafted using TIG welding, a process renowned for producing exceptionally precise and leak-resistant bonds. The high-quality aluminum construction not only slashes overall weight compared to factory steel units but also delivers inherent corrosion resistance for years of service. This robust build tolerates engine vibration and thermal cycling without compromising integrity, ensuring reliable operation even in harsh road conditions. Made in the USA under stringent quality controls, the structure stands up to repeated use without warping or developing weak points.
Dual high-performance Fans Deliver Uniform Airflow
A matched pair of electric fans works in concert to draw air through the full width of the core, maintaining stable coolant temperatures during idle or low speed traffic. Each fan operates according to precise thermal thresholds, allowing rapid response to sudden load changes. By covering more surface area than a single fan setup, this system prevents hot spots and improves airflow consistency under demanding conditions. The result is steady engine temperature control during stop-and-go driving and challenging towing scenarios.
Coating Choices Provide Protection and Visual Appeal
Customers can select a classic bare aluminum finish for a timeless mechanical look or choose a black epoxy coating for enhanced corrosion protection and a sleek appearance. The epoxy layer bonds tightly to the aluminum surface, shielding it from road debris, salt spray, and other environmental factors that can trigger oxidation. Even in coastal or winter climates, the coated option maintains its finish without flaking or discoloration. Both treatments preserve the radiator's thermal performance while adding style under the hood.
