Standard Ignition Engine Cooling Fan Switch P/N:TS-297
Standard Motor Products
Keep your cooling fan cycling on cue with the Standard Ignition Engine Cooling Fan Switch (TS-133), a factory-calibrated thermal switch that reads coolant temperature and signals the fan controller. This Standard Ignition switch is a direct-fit replacement for many vehicles, among them the 1984-1985 Nissan Sentra, 1983-1986 Nissan Pulsar NX and 1986 Nissan Tsuru; see the "Vehicles it fits" section for the full list.
Mechanically, it uses a custom wax formulation that expands when heated to trigger a snap-action electrical contact, transferring the signal to the fan controller so the cooling fan energizes at its set temperature. If a failed fan switch is the cause of a fan that won't come on or runs constantly, this replaces it.

This part cross-references / interchanges with the following part numbers:
What does the Standard Ignition switch TS-133 do?
It's a coolant-activated cooling fan switch. Wax inside expands as coolant heats, triggering a snap-action contact that signals the fan controller to turn the cooling fan on at the set temperature.
Which vehicles does the TS-133 fit?
It fits many vehicles, among them the 1984-1985 Nissan Sentra, 1983-1986 Nissan Pulsar NX and 1986 Nissan Tsuru. See the "Vehicles it fits" section for the full list.
What are signs this fan switch may need replacing?
A cooling fan that never turns on, runs constantly, or cycles at the wrong temperature can point to a failed switch. Diagnose the cause first, since wiring, the relay, or the controller can produce the same symptoms.
How is this switch calibrated?
Each unit is factory-calibrated and tested to make electrical contact at its specified lower-temperature set point, using wax pellets custom-formed for the required temperature range.
What numbers does the TS-133 cross-reference?
It interchanges with 17-1066 (171066), TFS520, 8426, SW525, FS156, 19021002, 2159536A00, and 21595D3000.
