Radiator for 1982-2004 Chevy S-10 SSeries (S10/Sonoma)
Swapping an LS engine into the classic SSeries S-10 demands a cooling solution that matches its power output and packaging constraints. This aluminum radiator for automatic transmission models bolts directly to original inlet locations and fits 4L60E and 4L80E applications without frame modifications. Crafted from high grade aluminum and TIG welded for a leak resistant seal, it balances weight savings with long life under towing or spirited runs. Its dense fin arrangement and optimized core design deliver superior thermal efficiency, keeping coolant temperatures in the ideal band during sustained load.
Precision TIG Welded Aluminum Structure
Crafted with 100 percent TIG welding, the tanks and core create a continuous bond that stands up to thermal cycling and engine vibration in an LS swap scenario. Each joint sets a uniform seam that resists fatigue over repeated heat and cool cycles, preventing leaks and ensuring consistent coolant pressure. The high quality aluminum offers strength without excess weight, so the assembly remains rigid under load while trimming mass for better handling. Built in the USA, each radiator meets strict quality control standards for consistency and reliability. As a result, this build delivers a reliable platform for sustained performance on the road or under tow.
High Conductivity Fin and Tube Arrangement
The precision wound core features closely spaced tubes and a dense fin pattern to maximize surface area for coolant contact. This architecture accelerates heat transfer away from the engine during heavy towing or spirited highway driving by promoting rapid airflow through each fin channel. High quality aluminum construction further enhances conductivity, so heat moves from the coolant to the ambient air with minimal lag. The result is stable operating temperatures and a reduced risk of overheating under demanding conditions.
Corrosion Defense with Bare Aluminum and Epoxy Coatings
Operators can choose a polished bare finish for its natural heat reflection or a black epoxy layer that shields the surface from moisture and road grime. The uncoated aluminum disperses heat directly and resists surface oxidation, while the epoxy barrier blocks corrosive elements for extended service life. Both options preserve the core's integrity and maintain appearance in varied environments, whether you face coastal humidity or gravel roads. This flexibility lets builders match their engine bay styling without sacrificing function.
Direct Fitment for Automatic Transmissions
Designed to align with factory inlet and outlet locations, this radiator bolts directly to original mounting points on SSeries trucks equipped with 4L60E or 4L80E transmissions. By adhering to OEM dimensions, it eliminates the need for frame alterations or custom hose adapters, cutting installation time. Technicians benefit from a straightforward swap that preserves chassis integrity and maintains a clean engine bay layout. The result is a reliable cooling upgrade that blends seamlessly with stock architecture.
