Radiator for GM Truck Applications

APDI radiator part number 8011523 is built for GM truck and SUV applications that use a 34-inch core and do not use an engine oil cooler. It is a direct-fit cooling replacement for a wide range of Chevrolet and GMC models, including Chevrolet C1500, GMC Yukon, and Chevrolet Tahoe applications.

Key Features

• Plastic tank and aluminum construction for a lightweight, serviceable cooling assembly.
• 2-row core design with a 19-3/8-inch core height and 34-inch core width.
• 1-3/4-inch inlet and outlet diameters for matched hose connection sizing.
• Integrated engine oil cooler and transmission oil cooler provisions, each measuring 11-1/2 inches.
• Fits GM trucks and SUVs with the specified 34-inch core configuration.

Detailed Description

APDI 8011523 is a radiator for GM applications that require a 34-inch core and are listed without an engine oil cooler. The plastic tank aluminum design combines a lightweight tank-and-core layout with a 2-row core for heat transfer in demanding cooling systems. This radiator is listed for Chevrolet and GMC models such as C1500, K1500, C2500, K2500, C3500, K3500, Suburban, Tahoe, Blazer, and Yukon applications across the covered years. If you are replacing a worn or leaking radiator on a Chevrolet C3500HD or GMC C3500HD, APDI 8011523 matches the specified fitment and cooling configuration.

This part cross-references Spectra Premium CU1523 and OSC 1523 for the same application.

Common Problems It Can Address

• Coolant leaks from a cracked or aging radiator tank.
• Overheating caused by reduced cooling efficiency.
• Transmission fluid temperature issues tied to a failing cooler circuit.
• Restricted coolant flow from internal corrosion or blockage.
• Fitment issues when replacing a radiator with the wrong core size.

Installation Notes and Tips

Verify that the vehicle uses a 34-inch core and does not have an engine oil cooler before ordering. Confirm inlet and outlet hose sizes, cooler line routing, and mounting dimensions against the original radiator. Flush the cooling system and inspect hoses, clamps, and the radiator cap during installation to help prevent repeat failures.

Quality Assurance

APDI supplies replacement cooling components for GM applications, and this radiator is built to match the listed fitment and dimensional requirements for the specified vehicles.
