Four Seasons 37858 switch for the 2008-2018 Chevrolet Silverado 1500 and other vehicles senses engine coolant temperature and is also called a coolant temp sensor switch. It is engineered and tested to provide years of trouble-free operation.

  • Brass construction for accurate temperature sensing
  • Zinc coated terminal to resist corrosion
  • Color coded for easy identification
  • Contains gaskets, o-rings or seals to replace the product properly

A temperature gauge that reads erratically, a check engine light or a cooling fan that runs at odd times can mean the switch is wearing out. Those signs alone do not prove the switch is the problem, since a low coolant level can produce them too.

It is a direct-fit replacement listed for a wide range of Chevrolet, GMC, Cadillac and Buick models. Two of the most popular are the 2008-2019 GMC Sierra 1500 and the 2008-2013 Chevrolet Silverado 2500.
