LS and LT Engine Swap Radiator for 1988-1995 Chevy C/K 1500 Tahoe Suburban Yukon
When you swap an LS or LT motor into a 1988-1995 Chevy C/K Series GMT400 truck or full size SUV the 1988-1995 LS Radiator 28.25" Core Width (Manual Trans) with Fans delivers the precise cooling needed to tame heat buildup during towing and slow speed traffic. It installs on manual transmission models by slipping into factory mounting points with no frame modifications or custom brackets required. Boasting a 28.25 inch aluminum core and wide fin stack the assembly accelerates heat rejection under heavy load while dual high flow electric fans switch on as coolant temperature rises to maintain airflow at idle or in stop and go traffic. Constructed from full aluminum with precision TIG welds and built in the USA this radiator also offers long lasting corrosion resistance and direct fitment to C/K Series trucks and SUVs for dependable performance under sustained load.
Precision TIG Welding for Structural Integrity
The radiator's tanks and core are joined by precision TIG welding, which yields exceptionally smooth seams and uniform bead profiles. This technique ensures each junction withstands the repeated stress from coolant pressure and temperature swings common in towing and daily operation. Uniform welds reduce the risk of micro leaks and extend fatigue life under vibration, so the assembly remains reliable over many heat cycles. By using TIG welding on high-quality aluminum, the design achieves a balanced combination of strength and light weight. Installers benefit from a robust unit that requires no reinforcement brackets or alterations to the frame.
Extra Wide 28.25 Inch Core Maximizes Heat Dissipation
With a core width of 28.25 inches, this radiator offers one of the largest surface areas available for GM GMT400 swap applications. The expanded fin surface and thicker cooling passages allow coolant to shed thermal energy more rapidly, keeping engine temperature within safe limits during strenuous tasks. This wider core proves vital when hauling heavy loads uphill or crawling through gridlocked city streets, as it prevents rapid temperature spikes. It also reduces the likelihood of seal and gasket damage caused by extreme heat. The design supports steady performance in hot climates and long highway runs without compromise.
Dual Electric Fans for Continuous Airflow Control
The dual electric fans come preinstalled to ensure constant airflow through the core even when the vehicle is at a standstill. Each fan activates automatically as coolant temperature climbs, eliminating the gap in ventilation that leads to overheating in stop and go traffic. Mounting hardware aligns precisely with factory locations on manual transmission models, so there is no need for custom brackets or cutting into the radiator support. This arrangement provides consistent temperature regulation whether idling in town or cruising at speed on open roads. Technicians will appreciate the plug and play wiring harness that simplifies the electrical hook up.
Bare Aluminum or Epoxy Coating for Corrosion Defense
Customers can choose the natural finish of bare aluminum or opt for a black epoxy coating that forms a protective barrier against moisture, salt, and road debris. The epoxy layer is applied under controlled conditions to guarantee even coverage and strong adhesion, which resists peeling and chipping over time. Bare aluminum offers a clean industrial appearance while still providing inherent corrosion resistance from anodic properties. Both finish options reveal the quality of the weld beads and core construction. This choice allows owners to match factory appearance or add an extra measure of protection in harsh environments.
