1988-1995 Chevy C/K1500 Tahoe Suburban Yukon Radiator for LS and LT Swaps
Whether you are towing a heavy trailer or pushing an LS or LT swap hard on winding roads this 1988-1995 LS Radiator 28.25 Inch Core Width (Manual Trans) keeps coolant temperatures in check and drops directly into factory brackets on GMT400 C1500 K1500 Tahoe Suburban and Yukon models. By featuring a 28.25 inch core the radiator moves heat into passing airflow more efficiently than stock units while aligning hose ports with original plumbing for a hassle free installation. Crafted from fully TIG welded aluminum tanks and channels the assembly resists corrosion and chassis movement stress to deliver steady performance in the toughest duty cycles.
Superior Heat Rejection with 28.25 Inch Aluminum Core
The 28.25 inch wide aluminum core of this radiator substantially increases the area where coolant interfaces with airflow. By channeling fluid across a broader network of tubes and fins, heat is drawn away rapidly during demanding tasks such as towing or spirited driving on warm days. Aluminum's high thermal conductivity moves stored warmth outward to the fin pack where passing air carries it away, limiting temperature spikes even under heavy load. The careful spacing of channels ensures a uniform temperature profile across the entire core, preventing isolated hot spots that can degrade fluid life. Integrating smoothly with the factory fan shroud allows uninterrupted airflow and keeps cooling performance consistent without relying on auxiliary units.
Precision TIG Welded Aluminum Structure
Precision TIG welding joins each tank and core interface with a continuous, flawless seam that resists vibration and thermal cycling. This welding method uses a focused arc and compatible filler to maintain the full strength of the aluminum, avoiding weak points commonly seen in other join techniques. The uninterrupted weld bead seals microscopic gaps, preventing coolant seepage as the radiator flexes in response to chassis movement or highway vibration. The result is a monolithic assembly that stands up to frequent temperature changes and heavy loads without fatigue. Technicians will note fewer maintenance intervals and greater confidence in durability compared with stock cooling units.
Durable Bare Aluminum and Epoxy Coating Options
Customers can choose a bare aluminum finish or an epoxy coating in black to suit different environmental demands. The untreated surface relies on aluminum's natural oxide layer to block corrosion while allowing quick visual checks for signs of damage or fluid leakage. The black epoxy is applied uniformly over tanks and fin edges, creating a barrier against road salt, moisture and debris without clogging the critical airflow passages between fins. This protective layer adheres through the welded seams, ensuring long term resistance to harsh conditions such as coastal climates or winter salt treatment. Both finish options are tailored to preserve full core efficiency and maintain a clean appearance under the hood.
Effortless Direct Fitment for GMT400 Chassis
Engineered to fit the factory supports on GMT400 chassis from 1988 to 1995 models including C1500 and K1500 trucks as well as Tahoe, Suburban and Yukon SUVs, this radiator requires no special brackets or modifications. Hose connections align exactly with original plumbing to maintain correct routing and reduce the chance of kinks that can restrict coolant flow. By preserving the factory geometry, coolant pressure remains within original specifications and helps avoid unexpected spikes under load. Installers can mount and connect the radiator using standard hand tools, cutting labor time and minimizing error during an LS or LT swap. The seamless integration with existing fan shrouds and hose layout yields a finished installation that looks factory made and performs reliably in any driving condition.
