Keep the engine's cooling fan cycling on at the right temperature with the Standard Ignition Engine Coolant Temperature Sender / Coolant Fan Switch TS-333. This thermal switch reads coolant temperature and passes the signal to the fan controller, and it installs as a direct-fit replacement for a long list of late-1980s through 2000 Chrysler, Dodge, Eagle, Mitsubishi and Plymouth applications — among them the 1987-1988 Chrysler Conquest, 1991-1994 Dodge Colt, 1987-1990 Dodge Ram 50, 1989-1990 Eagle Summit, 1986-1996 Mitsubishi Mighty Max and 1987-2000 Mitsubishi Montero (see the Buyer's Guide tab for the full list).

  • Factory-calibrated set point: every unit is calibrated and tested to confirm switch actuation, making electrical contact at its specified lower-temperature set point.
  • Temperature-activated contact: a temperature-sensitive element expands when heated to activate the electrical contact and transfer the signal to the fan controller.
  • Bimetallic contact arm: a formed bimetallic arm uses the differing expansion rates of two metals fused together — a creep-action device for precise performance.
  • Built for service: robust design and high-grade materials, with a single male blade terminal and a single plug-in spade connector for bolt-on installation.

Frequently Asked Questions

What does the TS-333 do?

It is a thermal switch that senses coolant temperature and, at its calibrated set point, makes electrical contact to signal the cooling fan controller.

Is this a temperature sender or a fan switch?

It is cataloged under both names — Engine Coolant Temperature Sender and Coolant Fan Switch — so you may find it listed either way. The MPN is TS-333.

What are signs this switch may need replacing?

Signs it may need replacing include the cooling fan not turning on and the engine running hot, or the fan running constantly. These have other causes, so diagnose the cooling system before replacing.

Which vehicles does the TS-333 fit?

Listed applications include the 1987-1988 Chrysler Conquest, 1991-1994 Dodge Colt, 1987-1990 Dodge Ram 50, 1986-1988 and 1990 Mitsubishi Galant, and 1987-2000 Mitsubishi Montero. See the Buyer's Guide tab for the full list.

What connector does it use and where is it made?

It has a single male blade terminal with one plug-in spade connector and uses a bolt-on attachment. Country of origin: Japan.
