One Stop Solutions Part Number 2793 is a crossflow radiator built for select Chevrolet Express and GMC Savana vans. It is engineered for OE-style form and function, with a premium aluminum core, plastic tanks, and an integrated plated transmission oil cooler for direct replacement service.

Key Features

• Premium aluminum core with plastic tanks for OE-style construction
• Crossflow design with one-row core layout
• Transmission oil cooler included; engine oil cooler not included
• Cadmium-plated tubes inside and out to help resist premature failure
• Die-cut gasket design to help reduce leak risk
• Individually pressure tested during production
• Drop-in fit, form, and function for easier replacement
• Part Number 2793 is engineered for multi-fit applications without changing the original look

Detailed Description

This radiator is designed for vehicles that need a direct-fit cooling system replacement with OE-style dimensions and cooling performance. Core measurements include a 30 1/2-inch height, 17 1/4-inch width, and 1-inch thickness, with 1 5/16-inch inlet and 1 9/16-inch outlet diameters. The unit uses a plated transmission cooler and includes the fittings and hardware specified by the manufacturer for the assembly. Part Number 2793 is built to address common wear points in high-mileage cooling systems by using enhanced fins, thicker core construction, and upgraded cooler capacity where applicable.

Compatible With 2004-2014 Chevrolet Express 1500, wo/EOC; 2004-2014 GMC Savana 1500, wo/EOC; 2004-2006 Chevrolet Express 2500, wo/EOC; and 2005 GMC Savana 2500, wo/EOC. This part cross-references Spectra Premium CU2793 and Koyorad A2793 for the same application.

Common Problems This Radiator Can Address

• Coolant leaks from a cracked or aging radiator tank
• Reduced cooling efficiency from clogged or weakened core passages
• Transmission fluid temperature concerns tied to a failing cooler circuit
• Overheating caused by worn internal radiator components
• Fitment issues when replacing an original OE-style crossflow radiator

Installation Notes and Tips

Verify core dimensions, inlet and outlet sizes, and transmission cooler connection spacing before installation. This radiator is specified for vehicles without an engine oil cooler, so confirm the original configuration matches the application notes. Flush the cooling system, inspect hoses and clamps, and check all connections for proper seating before refilling and pressure testing the system.

Quality Assurance

OSC radiators are produced with premium-grade components and are pressure tested during manufacturing, including cooler testing before tank installation, core testing before assembly, and a final assembled-unit test. The design follows OE-style cooler construction where originally equipped and uses engineering updates aimed at improving durability in demanding service.
