    Four Seasons 36403 switch for the 1999-2013 Chevrolet Silverado 1500 4.3L and other vehicles senses engine coolant temperature through brass construction and a two-terminal connector. It is also sold as an engine coolant temperature sensor.

    • Tested for trouble-free operation and backed by over 50 years of Four Seasons mobile A/C experience
    • Color coded for easy identification
    • Zinc coated terminal to resist corrosion
    • Comes with gaskets, o-rings or seals for replacing the switch
    • Brass construction for accurate temperature sensing

    A failing switch can show up as an erratic temperature gauge or a check-engine light, and a wiring or connector fault can look just the same. Before replacing it, look over the connector and terminals for corrosion and the switch body for coolant seepage, with the engine off and cool. Each vehicle takes one switch.

    The 1999-2013 GMC Sierra 1500 4.3L and the 2005-2009 Buick LaCrosse 3.8L are also on its fitment list, along with many other vehicles.
