Four Seasons 37889 switch for the 1987-1990 Jeep Wrangler and other vehicles senses engine coolant temperature and is also called a coolant temp sensor.

  • Engineered and tested for trouble free operation, backed by over 50 years of mobile A/C experience
  • Color coded for easy identification
  • Zinc coated terminal to resist corrosion
  • Contains gaskets, o-rings, or seals to properly replace the switch
  • Brass construction for accurate temperature sensing

A temperature gauge that reads erratically or a warning light can mean the switch is not reading coolant temperature correctly. Before you replace it, look over the connector and terminal for corrosion and the switch for coolant seepage, with the engine off and cool.

The same switch fits the 1987-1990 Jeep YJ and the 1984-1988 American Motors Eagle. If your Jeep or American Motors vehicle is a different model, open the Buyer's Guide tab to check your exact model and engine.
