Keep your engine’s cooling fan cycling on schedule with the Beck/Arnley Engine Cooling Fan Switch (P/N 201-1801) — the Echo switch that drops in for the 2000-2005 Toyota ECHO, 2001-2005 Toyota RAV4, and 2001-2005 Lexus IS300. This thermo fan switch senses engine coolant temperature and closes to signal the cooling fan (or fan relay) once coolant reaches its set point, then opens again as the coolant cools.
- Matches OE form, fit and function: designed as a direct replacement for the original switch on the listed applications.
- Application specific: check the catalog data and confirm fit for your vehicle before ordering.
- Professional diagnostics recommended for a successful repair.
- Verify the circuit: check cooling fan motor current draw, control module/relay function, and the electrical wiring and connectors.
If a failed fan switch is the cause of a fan that won’t turn on or one that runs constantly, this replaces it — but diagnose the cause first, since overheating and fan faults can also come from the fan motor, relay, control module, or wiring.
