Keep your cooling fan cycling on cue with the Standard Ignition Engine Cooling Fan Switch TS-256 (also written TS256). This coolant fan switch drops in as a direct-fit replacement for the 1989-1992 Ford Probe — see the Buyer's Guide tab for the full engine-level application detail. It monitors engine coolant temperature and closes an electrical contact at its specified temperature set point to signal the fan controller, helping keep the cooling fan operating when the engine needs it.
- Temperature-calibrated switching: factory-calibrated and tested to make electrical contact at the specified lower-temperature set point, then transfer that electrical signal to the fan controller.
- Snap-action contact: a formed contact arm delivers precise, repeatable actuation as temperature rises.
- Built for service demands: robust design and high-grade materials meet the stringent demands of today's service professional.
- OE-focused quality control: maintained throughout the manufacturing process from componentry to finished product.
If a failed coolant fan switch is the cause of your overheating or a fan that won't cycle, this replaces it. Signs it may need replacing include a cooling fan that stays off, runs constantly, or an engine that runs hotter than normal — diagnose the cause before replacing.
