Where is the Coolant Temperature Sensor located and How to its removal and installation on Pontiac G6?

On four-cylinder models the ECT sensor is mounted on the thermostat housing in the left rear corner of the cylinder head. Start by pulling off the radiator cap and then using water pump to 'pull a vacuum' on the cooling system, to get the level below that of the ECT sensor. Pull off the electrical connector of the ECT sensor and then using a deep socket, extension and ratchet, unscrew and pull out the ECT sensor. When it is time to install the new sensor, ensure that the threads are coated with Teflon tape so that they do not leak. After that the installation process is vice versa as the removal process and make sure that the sensor is tightened to the next torque value. Last of all, add in the refrigirant of the cooling system. For 3.5L and 3.9L V6 models, the ECT sensor is located in the right-front area of the engine, right end of the front cylinder head. The process is similar: flush it with antifreeze, pull the electrical connection, pull the sensor from its casing and remove it, thread the new one with teflon tape, reinstall it and tighten then replace the fluid. On most 3.6L V6 models, the ECT sensor is attached right over the number 4 exhaust port at the front side of the engine. Release the connection of the electrical connector, remove the sensor while dealing with the coolant leakage, if there is any, thread the Teflon tape around the threads and replace the sensor tightly, then check of coolant leakage.

How to replace the Coolant Temperature Sensor on Pontiac Vibe?

The engine coolant temperature (ECT) sensor is a thermistor that is a resistor that changes its resistance value based on temperature changes. This change in resistance directly affects the voltage signal from the sensor to the PCM. The sensor's resistance values increase when the temperature decreases, but they decrease as the sensor temperature increases. Any problem in the ECT sensor circuit will set a diagnostic trouble code (DTC). To replace this sensor, make sure that you turn off the ignition key and drain about one gallon from the cooling system. The electrical connector should be disconnected before carefully unscrewing the sensor. Wrap Teflon sealing tape around the new sensor's threads so as to avoid leakage and thread corrosion. Installation is simply opposite of removal. Nevertheless, pay attention to how you handle coolant sensors because if damaged, it will affect normal operation of entire fuel injection system. Finally, add coolant as required.

Pontiac Coolant Temperature Sensor maintains sharpness in the engine timing by supplying real-time heat data on the coolant to the computer. Pontiac had stripes by balancing wide-track stability with aggressive lines and allowing drivers to feel grounded in corners but the interior layout remained driver oriented, turning the Firebird and Grand Am into daily fun machines with hard-hitting powertrains and sleek-line styling that even now urge us to move the vehicle even when it is idle. Pontiac maintained a sense of excitement by changing sheet metal and dashboards regularly and was willing to make each update more radical, so each update featured grilles that were bolder, suspensions that were tighter, and electronics that were intelligent enough to encourage their owners to push its limits and remain in control on any back road. Pontiac also took the technology that was more focused on performance over flash and selected the components that only served to enhance throttle reaction, steering feedback, and general performance, as nothing kills the fun of driving more quickly than gimmicks that fail. The Coolant Temperature Sensor is installed in the engine coolant flow and measures the liquid heat every split second and transmits the exact voltage signal which is then decoded by the ECU to timing, fueling, and cooling fan commands that maintain combustion clean and power delivery crisp through the revs. In cases where the Coolant Temperature Sensor reading shifts with age, the engine might crank rich, may run rough in hot weather, or may cause a dashboard display, hence replacing it will restore fast igniting and stable idle. A new Coolant Temperature Sensor is inexpensive, it can be installed in a few minutes with simple tools and it has been compensated by the fact that it gives better mileage and longer life of the catalysts.
