Detailed Description

OSC Part Number 2043 is engineered as an OE-style replacement radiator for 1996-2002 Chevrolet Express and GMC Savana vans, including diesel applications on 1999-2002 Express 2500, Express 3500, Savana 2500, and Savana 3500 models. It also covers earlier 1996-1998 and 1997 applications listed for Express and Savana variants. The radiator uses a 34-inch core height, 17 1/4-inch core width, and 2-3/16-inch core thickness, with 1 13/16-inch inlet and outlet diameters and 18 7/16-inch header lengths.

This radiator includes plated engine and transmission oil cooler sections and is built to factory-style specifications for fit and function. OSC also tests the cooler circuits before tank installation, checks the core before assembly, and retests the completed unit to verify performance. This makes Part Number 2043 a practical replacement for high-mileage vans that need stable cooling and dependable fluid temperature control.

This part cross-references APDI 8012043 and Spectra Premium CU2043 for the same application.

What It Helps Address

• Overheating caused by a failing or restricted radiator
• Coolant leaks from cracked tanks, worn seals, or damaged core joints
• Transmission fluid temperature issues tied to a weak cooler circuit
• Engine oil cooling concerns on equipped applications
• Cooling performance loss in high-mileage Chevrolet Express and GMC Savana vans

Installation Notes and Tips

Verify radiator dimensions, cooler style, and hose connections before installation. This unit does not include a cap. Confirm the vehicle’s original cooling layout matches the listed fitment, especially on 1996 models with 34-inch core notes and 1996 GMC Savana 2500 and Savana 3500 new body style applications. For best results, inspect hoses, clamps, and coolant condition during replacement.

Quality Assurance

OSC builds this radiator with premium materials, factory-style component placement, and pressure testing throughout production. The design includes enhancements aimed at addressing common original-equipment failure points and improving durability in higher-mileage service.
