Detailed Description

Part 13476 uses premium-grade aluminum construction with cadmium-plated tubes inside and out to help resist premature failure. OSC builds the radiator to OE cooler design standards and does not substitute aluminum coolers where stainless steel plate or copper-and-brass concentric coolers were originally used. The unit includes plated transmission and engine oil cooler sections, with cooler fitting spacing of 11 1/2 in. and header dimensions sized for factory-style installation. For Chevrolet Express and GMC Savana owners, this radiator supports direct replacement needs while maintaining the original look and fit.

This part cross-references Spectra Premium CU13476 for the same application.

Common Repair Uses

• Overheating caused by a restricted or leaking radiator core
• Transmission temperature issues related to a failing integrated cooler
• Engine coolant loss from cracked tanks or worn seals
• Cooling system service on high-mileage Chevrolet Express and GMC Savana vans
• Replacement after corrosion, impact damage, or internal cooler failure

Installation Notes and Tips

Verify sensor-equipped vehicle coverage before ordering. Confirm inlet and outlet hose sizes, cooler line spacing, and overall core dimensions against the original radiator. Transfer any required vehicle-specific components during installation and inspect all hose connections, cooler fittings, and mounting points before returning the vehicle to service.

Quality Assurance

OSC tests the transmission and engine oil coolers before tank installation, checks the radiator core before assembly, and tests the completed unit again after assembly. Components are fitted and torqued to factory specifications, and the design includes enhancements aimed at improving durability and cooling life on higher-mileage vehicles. Part Number 13476 is built for OE-style performance and repeatable fitment on the listed Chevrolet and GMC applications.
