Standard Ignition Engine Cooling Fan Switch P/N:TS-133
Standard Ignition Engine Cooling Fan Switch P/N:TS-133
$54.99

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 the 1982-1984 Porsche 928, 1983-1986 Nissan Pulsar NX, 1984-1985 Nissan Sentra, 1985 Nissan Stanza, and 1986 Nissan Tsuru.

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.

  • Wax-pellet actuation: custom-formed wax pellets are matched to the specified temperature range for consistent switch operation.
  • Factory-calibrated: every unit is calibrated and tested to confirm actuation at its specified lower-temperature set point.
  • Bimetallic contact arm: a formed bimetal arm using the differing expansion rates of two fused metals provides precise, creep-action performance.
  • Service-grade build: robust design and high-grade materials for demanding service use.

Frequently Asked Questions

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's a direct-fit for the 1982-1984 Porsche 928, 1983-1986 Nissan Pulsar NX, 1984-1985 Nissan Sentra, 1985 Nissan Stanza, and 1986 Nissan Tsuru. Confirm your application in the Buyer's Guide tab.

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.
