The construction uses premium-grade radiator components and is tested during production to verify the core and assembled unit. This part cross-references Koyorad A13419 and Spectra Premium CU13419 for the same application.

Common Repair Uses

• Overheating caused by a worn or inefficient radiator
• Coolant loss from aging radiator tanks or core fatigue
• Reduced cooling performance in high-mileage vehicles
• Replacement after leaks, corrosion, or internal blockage
• Restoring proper engine temperature control in GM truck and SUV cooling systems

Installation Notes

Verify radiator width, core thickness, and cooling-system equipment before installation. This unit is listed for automatic transmission applications and does not include engine oil cooler or transmission oil cooler provisions. Match the vehicle’s original configuration to the fitment notes, especially the 34-inch width and 1-inch thickness references shown in the application data.
