Engine Coolant Temperature Sensor Connector

Standard Ignition S3099 is an engine coolant temperature sensor connector built for Hyundai and Kia applications that need a direct-fit electrical repair at the sensor harness. It features a rectangular male connector housing with a female blade terminal design and a 4-wire layout for a secure OE-style connection.

Use this connector when servicing coolant temperature sensor wiring on vehicles such as the Hyundai Sonata, Hyundai Santa Fe, Kia Optima, and Kia Sorento. The S3099 harness measures 43 cm (17.5 in.) long and uses 18-gauge wire for a practical repair-length lead.

  • Engine coolant temperature sensor connector for electrical harness repair
