- Brass casing: Built on Standard Motor Products' proprietary brass casing, designed for durability.
- Connector made for fitment: A single round female connector with two male pin terminals, designed to give the reliable connection that engine management systems depend on.
The TX3 is a screw-in sensor. It sends coolant temperature information to the engine management system, which uses the signal as it manages engine operation in hot and cold conditions. The listed applications use one sensor each. The wiring harness, hardware and mounting brackets are not included.
Signs this part may need replacing include a check engine light with a coolant-temperature code, hard starting, rough idle or reduced fuel economy. These symptoms can have other causes, so diagnose the system first. If a failed coolant temperature sensor is the cause, the TX3 replaces it.
Country of origin: Mexico.
