Keep your electric cooling fan switching on cue with the Standard Ignition Engine Cooling Fan Switch TS-394. This temperature-sensitive switch threads into the cooling system and monitors engine coolant temperature, opening and closing the cooling-fan circuit so the fan is commanded on and off at the intended coolant temperatures. It's a direct-fit replacement for the 1997-2003 Lexus ES300, 1999-2003 Lexus RX300, 1995-2004 Toyota Avalon, 1995-2006 Toyota Camry, 2001-2004 Toyota Highlander, 1998-2003 Toyota Sienna and 1999-2007 Toyota Solara — see the Buyer's Guide tab for the full application list.
- Coolant-temperature sensing: Responds to engine coolant temperature to switch the electric cooling fan circuit.
- Fan-circuit control: Completes or opens the fan circuit as coolant temperature rises and falls.
- Direct-fit replacement: Installs in place of the original switch on the listed applications.
Signs this switch may need replacing include a cooling fan that never runs, one that runs constantly, or coolant temperatures climbing higher than normal. If a failed fan switch is the cause, this part replaces it; diagnose the circuit first, since these symptoms can also come from the fan motor, relay, or wiring.

Frequently Asked Questions
What does the TS-394 cooling fan switch do?
It senses engine coolant temperature and opens or closes the electric cooling fan circuit, so the fan is commanded on and off at the intended coolant temperatures.
Will this switch fit my vehicle?
It's a direct-fit replacement for applications such as the 1995-2006 Toyota Camry, 1995-2004 Avalon, and 1997-2003 Lexus ES300. Check the Buyer's Guide tab for the full list.
What are signs this fan switch may be failing?
A cooling fan that never runs, runs constantly, or coolant temperatures rising higher than normal can point to the switch. Diagnose the circuit first, as the fan motor, relay, or wiring can cause the same symptoms.
What numbers does the TS-394 interchange with?
It cross-references TFS627, 8554, SW1436, FS267, 17-1152 (171152), and 8942841010.
If my fan won't turn on, will replacing this switch fix it?
If a failed fan switch is the cause, this replaces it. Because the fan motor, relay, or wiring can also be at fault, diagnose the circuit before replacing.
