Help keep cold air flowing to the cabin vents with the DENSO Auto Parts A/C Evaporator Core 476-0040, a front evaporator built as a direct-fit replacement for the 2003-2009 Toyota 4Runner and 2003-2005 Lexus GX470. Inside the HVAC case, the evaporator core is where refrigerant absorbs heat from the air blown across it before that air reaches the vents.
DENSO brings its OE experience in evaporator technology to the aftermarket. The configuration, tanks, fin pitch, core dimensions and materials of its evaporators are built to OE manufacturers' rigid specifications, and every DENSO First Time Fit® evaporator passes the company's strict durability and function tests. Engine details for each application are listed in the Buyer's Guide tab.
Signs this part may need replacing: weak or warm airflow from the vents with the A/C on, a refrigerant leak traced to the evaporator, or repeated loss of refrigerant charge. Other A/C faults can cause similar symptoms, so diagnose the system before replacing the core.
This part cross-references / interchanges with the following part numbers:
What does an A/C evaporator core do?
It sits inside the HVAC case and lets refrigerant absorb heat from the air the blower pushes across it, cooling that air before it reaches the vents.
Which vehicles does the DENSO 476-0040 fit?
It is a direct-fit front evaporator core for the 2003-2009 Toyota 4Runner and 2003-2005 Lexus GX470. See the Buyer's Guide tab for engine details.
What design features does this evaporator core have?
Thin tubes and short fins boost heat exchange, separate flow paths reduce pressure loss, a zinc layer adds corrosion resistance, and fin slits improve drainage.
What is involved in installing an evaporator core?
Replacement usually means recovering the refrigerant and opening the HVAC case, then evacuating and recharging the system afterward. Follow the vehicle service information for the full procedure.
What are signs the evaporator core may need replacing?
Common signs include weak cooling from the vents and refrigerant loss traced to the evaporator. Other A/C faults can cause similar symptoms, so diagnose the system first.
