Keep your engine’s electric cooling fan cycling on cue with the Beck/Arnley Engine Cooling Fan Switch (P/N 201-2690), also cataloged as a water temp switch. This is the Toyota Pickup switch and 4Runner switch that senses coolant temperature and opens or closes the cooling fan circuit. It installs as a direct replacement for the 1990-1995 Toyota 4Runner and 1992-1995 Toyota Pickup.
- OE form, fit and function: matched to the original equipment application for these foreign-nameplate vehicles.
- Built for the engine bay: constructed to withstand an engine environment with high-quality material and componentry.
- Durable construction: made to hold up to heat and vibration over repeated cycles.
- Application specific: sourced for this exact vehicle, not a universal fit.
The switch threads into the coolant passage and reacts to engine coolant temperature, signaling the electric fan to run once coolant reaches its set point and to switch off as it cools. Signs the original may need replacing include a fan that never turns on and lets the engine run hot, or a fan that runs continuously. If a failed switch is the cause, this part replaces it. Diagnose the circuit before ordering.
