Detailed Description

Four Seasons 54798 evaporator core is a replacement HVAC component for vehicles that use a springlock-connected A/C evaporator assembly. The aluminum plate & fin construction supports efficient heat exchange inside the climate control system, while the listed core dimensions and fitting sizes help match the original evaporator housing and refrigerant line connections. This part is used in 2006-2007 Ford Taurus, 1996-2005 Ford Taurus, 1996-2005 Mercury Sable, 1995-2002 Lincoln Continental, and 1996-2001 Ford Sable applications.

This part cross-references Spectra Premium 1054798 and UAC EV0154PFXC for the same application. Four Seasons 54798 is a practical replacement choice when servicing the evaporator core in Ford Taurus, Mercury Sable, or Lincoln Continental HVAC systems.

What It Helps Address

• Weak or inconsistent cabin cooling
• Refrigerant leakage at the evaporator core connections
• Corrosion or internal damage in the HVAC evaporator assembly
• Restricted airflow through a failing evaporator core
• Loss of A/C performance in Ford Taurus, Mercury Sable, or Lincoln Continental models

Installation Notes and Tips

Replacement of an A/C evaporator core can require extended labor, specialized tools, and HVAC service experience. Verify core dimensions, inlet and outlet fitting types, and springlock connection sizes before installation. Proper system evacuation, leak checking, and refrigerant recharge procedures should be followed after service. Confirm vehicle fitment by year, make, and model before ordering.

Quality Assurance

Four Seasons supplies HVAC replacement parts for vehicle-specific applications, and this evaporator core is built to match the listed dimensions and connection style for the confirmed fitment range. Use the part number 54798 to verify application details during catalog lookup and service planning.
