Keep your engine's cooling fan cycling on cue with the Standard Ignition Engine Cooling Fan Switch TS-379. This coolant fan switch senses coolant temperature and signals the fan controller to energize the cooling fan, and it drops in as a direct-fit replacement for the 1997-1999 Acura CL [All] and the 1998-2002 Honda Accord [All].
- Calibrated actuation: factory-calibrated and tested to make electrical contact at its specified temperature set point, then transfer that signal to the fan controller.
- Snap-action design: a custom wax formulation expands when heated to trigger a snap-action electrical contact.
- Connector and harness: includes a 5.5 in (139.7 mm) wiring harness, one square female connector, and two male blade terminals; rated for 12V.
- Bolt-on fitment: installs with a 5/8-18 thread; open at idle, with a plastic-and-metal housing.
Mounting hardware and mounting bracket are not included — consult the vehicle service information for the correct fasteners and whether they may be reused. If a failed cooling fan switch is the cause of your fan not cycling correctly, this replaces it; diagnose the circuit first, as other components can produce the same symptom. Country of origin: Japan.
