Performance Radiator for Chevrolet S-10 (1994-2003) 2.2L

Heavy-Duty All-Aluminum 3-Row Performance Radiator for 1994-2003 Chevrolet S-10

Direct-Fit Cooling Upgrade: Replaces failure-prone factory plastic-tank radiators with a high-capacity, all-aluminum 3-row core engineered to stabilize engine and transmission temperatures under heavy load.

The Stock S-10 Thermal Dissipation Bottleneck

Factory GMT325 cooling assemblies utilize crimped plastic end tanks paired with thin single-row aluminum cores. Over years of thermal cycling, the plastic side tanks become brittle and develop stress fractures along the crimp seams. Additionally, the restricted internal fluid pathways struggle to shed heat effectively during sustained hauling, stop-and-go idling, or towing, leading to accelerated transmission fluid breakdown and elevated cylinder head temperatures in the 2.2L inline-four.

The Engineering Solution

Constructed entirely from aircraft-grade aluminum, this 3-row crossflow radiator features 100% TIG-welded seams that permanently eliminate crimped plastic failure points. The expanded core measures 23.6" W x 14.9" H to dramatically increase surface area and coolant volume for superior heat rejection. It includes precision 1.3" inlet/outlet ports, an integrated passenger-side transmission fluid heat exchanger, and comes complete with a high-pressure radiator cap for drop-in reliability.
