Detailed Product Overview

Standard Ignition TS-256 is engineered for the cooling system on 1989-1992 Ford Probe models. The switch uses a wax-based thermal element and bimetal contact movement to transfer the electrical signal to the fan controller when the set temperature is reached. This design supports accurate fan engagement and consistent temperature-based switching. This part cross-references Four Seasons 36466 for the same application.

What This Switch Helps Address

  • Cooling fan not turning on at the proper temperature
  • Fan cycling inconsistently during engine warm-up
  • Overheating caused by delayed fan activation
  • Fault codes or drivability concerns tied to fan control input
  • Intermittent electrical contact at the cooling fan switch

Installation Notes and Tips

Verify connector style, terminal type, and temperature specification before installation. For Ford Probe cooling system service, confirm the replacement switch matches the original electrical connection and mounting location. Inspect the connector for corrosion or heat damage before installing TS-256.
