Four Seasons 37900 switch for the 1983-1986 Isuzu Pickup / P Up and other vehicles senses engine coolant temperature and has brass construction for accurate temperature sensing. It is also listed as a coolant temp sensor switch.

  • Engineered and tested for trouble-free operation, backed by over 50 years of mobile a/c experience at Four Seasons
  • Color coded for easy identification
  • Zinc coated terminal to resist corrosion
  • Contains gaskets, o-rings or seals to replace the switch properly

A temperature gauge that reads wrong or jumps around, or a related warning light, can mean the switch is failing. Before you replace it, rule out a wiring or connector fault and a problem in the gauge circuit, since either can show up the same way.

This switch also fits the 1983-1986 Isuzu Pickup and the 1983-1984 Isuzu I-Mark, as a direct-fit replacement for these vehicles.
