Installation Notes and Tips

Evaporator replacement on these Toyota applications may require considerable time, specialty tools, and training. Verify the block fitting style, core dimensions, and O-ring specification before installation. Because the evaporator is located within the HVAC case, proper system evacuation, recovery, and recharging procedures are required after service.

For fitment verification, use the vehicle year, make, and model exactly as listed: Fits 1997-2001 Toyota Camry, N/A; Fits 1999-2003 Toyota Solara, N/A.
