Detailed Description

This radiator is designed around OE dimensions and cooling requirements for Chevrolet Express and GMC Savana vans. OSC uses premium-grade aluminum tubes and fins, cadmium-plated tubes inside and out, and factory-style component placement to help maintain cooling performance and fit. Part number 2712 also cross-references Spectra Premium CU2712 and APDI 8012712 for the same application.

The radiator includes a transmission oil cooler and is built as a crossflow unit with plastic tanks and a single-row core. For 2003-2005 Chevrolet Express 1500, Chevrolet Express 2500, GMC Savana 1500, and GMC Savana 2500 fitments, this design supports direct replacement service where the original radiator has worn tanks, restricted flow, or cooler-related issues. One Stop Solutions 2712 is a practical OE-style radiator choice for these van platforms.

Common Problems This Radiator Can Address

• Coolant leaks from aged radiator tanks or seams
• Reduced cooling efficiency from clogged or damaged core passages
• Transmission fluid temperature concerns related to a failing cooler circuit
• Overheating caused by internal corrosion or restricted flow
• Fitment issues when replacing a damaged OE-style radiator

Installation Notes and Tips

Verify inlet and outlet sizes, cooler line spacing, and clamp-on hose configuration before installation. Inspect hoses, clamps, and mounting points during replacement, and flush the cooling system if contamination or corrosion is present. Confirm that the transmission cooler connections match the vehicle’s original setup before final assembly.

Quality Assurance

OSC radiators are individually pressure tested, with cooler circuits tested before tank installation and the completed radiator tested again after assembly. The design uses OE-form engineering, fitted components, and leak-resistant gasket construction to support consistent service life.
