Global Parts 2537C Radiator

Radiator for GM Truck Cooling Systems

Global Parts 2537C is a cross flow radiator built for select Chevrolet Silverado and GMC Sierra HD applications, along with the 2001 GMC Yukon XL 2500. It uses an aluminum core with plastic tanks and includes both engine oil cooler and transmission oil cooler provisions for direct cooling-system service.

Key Features

• Aluminum core with plastic tanks for OE-style construction
• Cross flow design for efficient heat transfer
• Core thickness: 2.2 in. (55.88 mm)
• Inlet diameter: 1.57 in. (39.88 mm)
• Engine oil cooler included with quick-connect fittings
• Transmission oil cooler included with 11.5 in. fitting spacing
• Core fin quantity: 58 per 4 in.

Detailed Description

Global Parts 2537C radiator is engineered for vehicles that rely on integrated cooling for both engine temperature control and fluid temperature management. The aluminum core supports heat dissipation, while the plastic tank construction follows common OE radiator architecture. This unit includes an engine oil cooler with 0.63 in. quick-connect fittings and a transmission oil cooler with 11.5 in. fitting distance, making it a practical replacement for trucks and SUVs that use factory cooler circuits. This part cross-references Spectra Premium CU2537 and UAC RA2537C for the same application. Compatible with 2001-2002 Chevrolet Silverado 2500 HD, 2001-2002 Chevrolet Silverado 3500, 2001-2002 GMC Sierra 2500 HD, 2001-2002 GMC Sierra 3500, and 2001 GMC Yukon XL 2500, Global Parts 2537C supports the cooling needs of these GM platforms.

What This Radiator Helps Address

• Engine overheating caused by reduced radiator heat rejection
• Transmission fluid temperature buildup in tow or load conditions
• Oil temperature management issues in vehicles with factory cooler circuits
• Leaks or tank damage in aging OE-style radiator assemblies
• Restricted coolant flow from worn or inefficient radiator cores

Installation Notes and Tips

Verify inlet diameter, cooler fitting style, and cooler spacing against the original radiator before installation. Confirm whether the vehicle uses transmission oil cooler equipment and engine oil cooler connections, especially on 2002 Silverado 2500 HD, 2002 Silverado 3500, 2002 Sierra 2500 HD, and 2002 Sierra 3500 models marked w/ TOC. Inspect hoses, clamps, and cooler lines for wear before transferring the new radiator into service. Proper coolant fill and system bleeding are important after installation.

Quality Assurance

Global Parts supplies radiator components for cooling-system replacement applications, with specifications listed to support accurate fitment and OE-style service on Chevrolet Silverado, GMC Sierra, and Yukon XL platforms.
