What does a coolant temperature sensor do?

The coolant temperature sensor monitors the engine's coolant temperature and sends this information to the vehicle's computer. This data is used to adjust fuel injection, ignition timing, and idle speed for optimal engine performance and efficiency.

How do I know if my coolant temperature sensor needs replacing?

Common signs include an inaccurate temperature gauge reading, a check engine light with codes related to engine temperature, poor fuel economy, or rough idling. If you notice any of these symptoms, it's a good idea to have the sensor checked.

Does this sensor come with any hardware or sealant?

This Omix coolant temperature sensor is designed as a direct, thread-in replacement and typically does not include additional hardware or sealant. Refer to the manufacturer's installation instructions for any specific recommendations.
