Engine Coolant Temperature Sender for Lexus

Standard Ignition TS-602 is an engine coolant temperature sender built for vehicles with gauge applications. It uses a bolt-on attachment method and a single male bullet terminal with a round male connector, making it a direct-fit style replacement for the original sender on supported Lexus models.

Compatible with Lexus GS300, GS430, GS400, and IS300 applications that use gauges, this Standard Ignition TS-602 coolant temperature sender supports accurate temperature signal transfer to the instrument cluster. If you are replacing a faulty Lexus GS300 coolant temperature sender or sourcing a TS-602 replacement for a gauge-equipped Lexus V8 or inline-six application, this part matches the listed fitment.

  • Engine coolant temperature sender for gauge-equipped applications
  • Bolt-on attachment method for secure mounting
  • Round male connector with one male bullet terminal
  • Direct replacement format for supported Lexus applications
