Detailed Description

Global Parts 1489C is a direct-fit style radiator for 1992-1993 Chevrolet G10, G20, and G30 vans and 1992-1993 GMC G1500, G2500, and G3500 vans with engine oil cooler requirements and a 30-1/2 in. core. The radiator is designed around a 1-row aluminum core for efficient heat transfer, while the plastic tanks help keep the assembly lightweight and service-friendly. This part number 1489C also cross-references Spectra Premium CU1489 for the same application.

What It Helps Address

• Engine overheating from a restricted or leaking radiator
• Transmission temperature issues tied to a failing cooler circuit
• Oil temperature control problems when the internal cooler is compromised
• Coolant loss from cracked tanks or corroded core passages
• Reduced cooling performance in high-load van applications

Installation Notes and Tips

Verify the vehicle uses the 30-1/2 in. core configuration and engine oil cooler setup before ordering. Compare hose locations, cooler line routing, and mounting points to the original radiator. Flush the cooling system, inspect hoses and clamps, and replace the radiator cap only if the existing unit is confirmed serviceable, since a cap is not included with 1489C.

Quality Assurance

Global Parts supplies cooling components for service replacement applications, and this radiator is built to match the listed fitment for 1992-1993 Chevrolet G10, G20, and G30 and 1992-1993 GMC G1500, G2500, and G3500 models.
