LS and LT Engine Swap Radiator for 1967-1987 GM C/K Trucks Blazer and Suburban
When fitting an LS or LT motor into a 1967 to 1987 C/K Series or Blazer and Suburban, the 18.5 inch tall manual transmission radiator maintains factory coolant routing and adds nearly twenty percent more fluid capacity to handle heavier loads. Installation follows original mounting points to preserve steering clearance and hood latch operation on SquareBody trucks. Cooling performance stays consistent under towing or spirited driving thanks to an aluminum core that dissipates heat quickly and resists corrosion over time. Every unit is built in the United States with reinforced end tanks and precise tolerances to deliver reliable fitment on manual transmission applications without trimming or filler panel changes.
Exact Factory Height for LS and LT Manual Transmissions
When installing an LS or LT engine into a 1967 to 1987 C/K Series truck or Blazer and Suburban chassis the 18.5 inch tall radiator aligns precisely with the original mounting points to preserve core support integrity. It follows the factory coolant line routing to avoid interference with steering linkages and hood latch hardware. The manual transmission version has been engineered to fit without any trimming or filler panel adjustments so technicians can complete the installation using stock brackets. Access to hose connections and the fan shroud remains unchanged which helps service technicians perform routine maintenance with familiar procedures. In use it delivers consistent coolant flow during both low speed towing and spirited highway driving without compromising engine bay clearance.
Aluminum Core for Rapid Heat Dissipation
The radiator core is constructed from premium aluminum renowned for its high thermal conductivity and resistance to corrosion. Its increased volume holds nearly twenty percent more coolant than the original design creating a larger thermal buffer that slows temperature spikes under heavy loads. Even coolant distribution across the taller core minimizes hot spots that can stress head gaskets during towing or performance runs. The lightweight nature of aluminum also reduces mass at the front of the truck which can improve steering response and braking performance. Over thousands of heat cycles this material preserves its shape and cooling efficiency without developing fatigue or internal leaks.
Selectable Protective Coatings to Guard Against Corrosion
Owners may choose between a classic bare aluminum finish or a durable black epoxy coating depending on aesthetic and environmental needs. The epoxy option forms a uniform barrier that adheres strongly to the metal surface to slow oxidation in humid or road salt exposed regions. Bare aluminum retains its natural shine while providing inherent corrosion resistance that appeals to restoration enthusiasts seeking an authentic look. Both finish processes are performed in the same US facility that extrudes and forms the core ensuring consistent surface preparation and cure times. This integrated approach delivers a protective layer that withstands road debris impacts and exposure to coolant additives over time.
Made in the USA with Rigorous Quality Controls
Every radiator is produced in US based operations that oversee each step from extrusion of core plates to final assembly of end tanks and inlet connections. Strict inspection protocols verify wall thickness uniformity and dimensional accuracy to eliminate common sources of coolant leaks and fitment issues. Local production not only shortens lead times for replacement parts but also provides direct access to technical support and service documentation. A traceable build record accompanies each unit ensuring buyers can reference manufacturing details if service or warranty support is required. This domestic approach results in a product that meets or exceeds original factory standards and retains value through durable performance.
