Cooling System Replacement Details

This Global Parts radiator 2948C is built for vehicles that need a direct-fit cooling system replacement with integrated fluid cooling provisions. It is a practical choice for a Chevrolet Suburban 2500 radiator replacement, a Silverado 2500 HD radiator replacement, or a GMC Sierra 3500 radiator replacement where the original unit has failed and stable heat dissipation is required for normal engine operation.

This part cross-references APDI 8012948 and UAC RA2948C for the same application.

What This Radiator Helps Address

• Coolant leaks from a cracked or aging radiator tank
• Overheating caused by reduced heat transfer through the core
• Transmission temperature concerns when the cooler circuit is part of the failure
• Engine oil cooling issues tied to a damaged radiator assembly
• Restricted flow from corrosion, sediment, or internal blockage
