What It Helps Fix

• Warm air from the vents caused by an evaporator leak
• Reduced cabin cooling from a restricted evaporator core
• Refrigerant loss at the evaporator connection points
• HVAC performance issues tied to a damaged aluminum core
• Service replacement needs during A/C system repair on Toyota Celica models

Installation Notes

Verify the core width, height, and depth against the removed unit before installation. Confirm block fitting alignment and use the correct green O-ring specification at the connection points. Because evaporator replacement typically requires HVAC system disassembly, inspect related seals, expansion components, and refrigerant lines during service. Fits 1994 Toyota Celica, N/A, to 9/93. Fits 1990-1993 Toyota Celica, N/A.
