1988-1993 Chevy C1500 K1500 Suburban Radiator for LS and LT Engine Swaps
When converting a GMT400 C/K Series truck to an LS or LT engine with manual transmission, choosing the right cooling package is critical for reliable heat management. This 34 inch core radiator fits into the factory mounts on 1988-1993 Chevy C1500, K1500 and Suburban models without cutting or adapter brackets while preserving original hose locations and fan shroud clearance. Crafted with TIG welded high grade aluminum tanks joined to the full width core, it ensures a leak free seal under vibration and thermal cycling. As a result, coolant flow remains consistent and engine temperatures stay in check during towing or extended high load driving.
Seamless Integration into GMT400 C/K Series Frames
This radiator slips directly into the existing mounting points of 1988-1993 Chevy C1500, K1500, and Suburban trucks equipped with a manual transmission, eliminating trimming or adapter brackets. By matching the factory hose connections and preserving the original fan shroud clearance, it maintains the intended airflow path and avoids common fitment issues during LS or LT engine swaps. Installers experience consistent alignment of coolant lines and brackets, which reduces labor time and the chance of misrouted hoses. The result is a plug-and-play cooling solution that retains the chassis geometry as designed by the manufacturer.
34 Inch Full Width Core for Superior Heat Dissipation
Featuring a 34 inch full width aluminum core, this radiator offers an expansive surface area that accelerates coolant flow and evenly disperses engine heat. Aluminum's thermal conductivity rapidly draws heat away from the block, preventing localized hotspots during heavy towing or spirited driving. The broad core design optimizes the contact between coolant and ambient air, ensuring that high-output LS and LT engines operate within ideal temperature windows. This consistency in cooling performance helps preserve internal components and supports sustained power delivery.
Precision TIG Welded Aluminum Structure
The tanks, end caps, and cooling tubes are joined with precision TIG welding, a process renowned for creating uniform, low-porosity bonds in aluminum assemblies. This technique ensures a leak free seal that resists cracking under repeated thermal cycling and engine vibration. Combined with the inherent corrosion resistance of aluminum, the robust construction yields a lightweight yet durable radiator capable of withstanding demanding conditions. Precision TIG welding also contributes to extending service intervals by minimizing potential failure points over time.
Custom Finish Options for Protection and Appearance
Builders can choose between the striking raw look of bare aluminum or a uniform black epoxy coating to match environmental demands and styling preferences. The epoxy finish adds a protective barrier against road salt, moisture, and contaminants, making it ideal for winter or coastal climates. In contrast, the untreated surface showcases aluminum's natural sheen and can be polished to a mirror-like glow. Both finishes preserve identical thermal efficiency, allowing for aesthetic personalization without sacrificing cooling capability.
