Product Details

The Airtex 5S8203 Engine Coolant Temperature Sensor is a precision-engineered component designed to monitor coolant temperature in your vehicle's cooling system. This sensor measures coolant temperature through changing resistance and transmits this critical information to the engine control module (ECM), allowing the computer to optimize engine performance, fuel efficiency, and emissions control.

Key Features:

  • Engineered and tested to meet or exceed OE specifications for reliable performance
  • Features 2-terminal electrical connector design for secure connection
  • Direct replacement for OEM part numbers 12609558, 12606657, 12601050, 12590959, and 12586299
  • Precision thermistor design provides accurate temperature readings across operating range
  • Allows ECM to adjust air/fuel ratio, ignition timing, and idle speed based on engine temperature
  • Quality construction ensures long service life and durability

This coolant temperature sensor is a critical component for proper engine operation, preventing issues such as poor fuel economy, rough idle, or engine overheating caused by faulty temperature readings. Professional installation is recommended to ensure proper sealing and electrical connection.
