Keep the engine cooling fan responding to coolant temperature with the Beck/Arnley Engine Cooling Fan Switch 201-1784, a thermo fan switch that installs as a direct-fit replacement for the 1999-2003 Lexus RX300, 1995-2004 Toyota Avalon, 1994-2003 Toyota Camry, and 1999-2003 Toyota Solara — see the Buyer's Guide tab for the engine-level details. This is the UPPER-position switch. It senses coolant temperature and opens or closes the cooling fan circuit so the fan cycles at the intended temperature; if a failed original switch is the cause of a fan that won't turn on or won't shut off, this replaces it.

What does this switch do?
It senses coolant temperature and opens or closes the engine cooling fan circuit so the fan cycles on and off at the intended temperature.
Which vehicles does it fit?
The 1999-2003 Lexus RX300, 1995-2004 Toyota Avalon, 1994-2003 Toyota Camry, and 1999-2003 Toyota Solara. Check the Buyer's Guide tab and confirm fit before ordering.
Is this the upper switch?
Yes. Catalog data lists this as the UPPER-position engine cooling fan switch for the applications shown.
My cooling fan won't turn on — will this fix it?
If a faulty switch is the cause, replacing it restores that function. The fan can also depend on the motor, relay, module, and wiring, so diagnose the cause first.
What else should I check during the repair?
Professional diagnostics are recommended. Verify the cooling fan motor current draw, control module or relay function, and the electrical wiring and connectors.
