Four Seasons 54616 Evaporator Core Overview

Four Seasons 54616 is an aluminum A/C evaporator core built for the HVAC system in select Toyota applications. With a plate & fin design, 9-1/2 in. width, 8-1/2 in. height, and 3-1/8 in. depth, it matches the dimensional requirements for direct replacement service in the cabin cooling circuit.

Compatible With 1991-1999 Toyota Tercel and 1992-1993 Toyota Paseo applications, this Four Seasons evaporator core is a fitment-based replacement for vehicles using No. 10 inlet and outlet block fittings. The Four Seasons 54616 part number is also referenced in aftermarket interchange listings for the same application.

Key Features

  • Aluminum evaporator core with plate & fin construction
  • Core dimensions: 9-1/2 in. wide, 8-1/2 in. high, 3-1/8 in. deep
  • No. 10 inlet and outlet fitting size
  • Block fitting inlet design
  • Uses green O-ring sealing points with OE-style fitment dimensions
  • Built for Toyota Tercel and Toyota Paseo HVAC service applications

Product Details

This evaporator core is the heat-exchange component inside the air conditioning system that absorbs cabin heat as refrigerant passes through the core. Four Seasons 54616 is sized for the listed Toyota fitments and uses an aluminum plate & fin layout to match the original HVAC packaging. If you are replacing a leaking, restricted, or inefficient A/C evaporator core on a 1992-1999 Toyota Tercel or 1992-1993 Toyota Paseo, this part number provides a direct-reference option for the correct application.

This part cross-references UAC EV16121PFXC for the same application.

Common Reasons for Replacement

  • Refrigerant loss from a leaking evaporator core
  • Weak cabin cooling caused by internal restriction
  • Corrosion or damage to the aluminum core
  • Persistent A/C odor from a contaminated evaporator assembly
  • Poor airflow performance through the HVAC evaporator section

Installation Notes

Verify the vehicle’s HVAC configuration, fitting style, and core dimensions before installation. Confirm No. 10 inlet and outlet connections and inspect the sealing surfaces and O-ring condition during service. Proper evacuation, leak testing, and refrigerant recharge procedures should be followed after replacement to restore system operation.

Quality Assurance

Four Seasons is a recognized aftermarket HVAC brand, and this evaporator core is built to match the listed application dimensions and fitting style for service replacement use.
