What is the purpose of the coolant temperature indicator system and Coolant Temperature Sensor on Chevrolet Impala?

The coolant temperature indicator system consists of a temperature gauge, warning light, and engine-mounted sensor. It monitors engine coolant temperature. The ECT sensor is crucial as it signals the PCM and BCM to operate the temperature gauge. To address overheating, check coolant level and mixture. If the gauge stays at C, inspect wiring connections. A faulty ECT sensor may trigger the Check Engine light, requiring sensor replacement or circuit repair.

How to replace the ECT sensor on Chevrolet Impala?

For V6 models,The location of the ECT sensor is on the left end of the front cylinder head. Drain the cooling system below the level of the ECT sensor. Unplug the ECT sensor from its electrical connector. Untwist and get rid of it. Wrap Teflon tape around the threads of your new ECT to prevent leakages. Reinstallation is just a reversal of removal operation. Remember to tighten up your ECT sensor properly. After completing all these steps, you need to refill your coolant system again. V8 models: The location of the ECT sensor is on the right end of the front cylinder head just above number one spark plug hole. Drain coolants so that their level becomes lower than that of ECT sensor. Unscrew and remove from this part as well as disconnecting its electrical connector with it first. This Teflon tape wrapped around ECT's threads will help in case liquid seeps out after installation in reverse order (of removal). Do not forget about tightening this device called an ECT sensor when everything else has been done already. Refill your coolant once through with this procedure accomplished entirely.
