Detailed Description

Universal Air RA556C is a crossflow radiator built for specific Ford Mustang, Lincoln Mark VII, Ford Thunderbird, Mercury Cougar, Lincoln Continental, Ford LTD, Mercury Capri, Mercury Marquis, Ford Fairmont, and Mercury Zephyr applications. The fitment data identifies a 2-row core design across the listed vehicles, with the Ford Mustang also noting a 24 core height requirement. Use RA556C when replacing a radiator on these model-year combinations and matching the listed core configuration.

Common Replacement Reasons

• Leaking radiator tanks or seams
• Restricted coolant flow from internal buildup
• Overheating caused by reduced heat transfer
• Physical damage to the radiator core
• Cooling system service on a Ford Mustang, Thunderbird, or Cougar

Installation Notes

Verify the vehicle’s core configuration before ordering, especially on 1980-1993 Ford Mustang applications that specify both 2-row core and 24 core height details. Confirm radiator dimensions, hose locations, and mounting points against the removed unit before installation. RA556C is listed for N/A position fitment.

Quality Assurance

Universal Air identifies this radiator under the Crossflow Radiator product line. Part number RA556C is cataloged for the specified applications and should be matched to the vehicle’s cooling system requirements before installation.
