Detailed Description

This Global Parts radiator, part number 2556C, is engineered for Audi A4 cooling system service where the factory radiator has failed or is no longer performing correctly. The radiator uses an aluminum core for heat dissipation and plastic tanks for OE-style construction, and it includes a transmission oil cooler for vehicles equipped with that setup. Core fin density is listed at 68 fins every 4 inches, supporting efficient airflow through the core. This part cross-references Spectra Premium CU2556 and UAC RA2556C for the same application.

What It Helps Address

  • Engine overheating caused by a leaking or restricted radiator
  • Loss of coolant temperature control during normal driving
  • Transmission fluid temperature concerns on equipped Audi A4 models
  • Cracked or aged plastic end tanks
  • Corrosion or internal blockage in the original radiator core

Installation Notes and Tips

Confirm vehicle fitment by year, model, and the presence of a transmission oil cooler before installation. Inspect coolant hoses, clamps, and related cooling system components for wear while replacing the radiator. Proper system bleeding and refill with the correct coolant specification are important after installation to help maintain stable operating temperatures.

Quality Assurance

Global Parts supplies replacement cooling components for direct-fit service applications. Part number 2556C is listed for the specified Audi A4 and Audi A4 Quattro fitments and follows the stated core, inlet, outlet, and cooler specifications for application matching.
