Coolant Temperature Sensor

One has to first turn OFF the ignition and relieve the coolant pressure to service the Coolant Temperature Sensor/Switch (For Computer). Soak the coolant just enough to avoid spillage upon removal ofyon sensor, then disconnect the ECT sensor to the electrical connector. Then with the help of a deep well socket and an extension, take off the sensor. For installation, apply on the thread of the engine coolant temperature sensor sealer P/N 9985253 or similar and put the sensor on the engine, then tighten the sensor with 23 N.m (17 lb ft). Reconnect the ECT sensor with its electrical connector, fill the coolant system, start the engine, and check for leaks and coolant level.

Start by turning the ignition OFF before draining coolant so that it reaches a level lower than the ECT sensor. After disconnecting the electrical connector you must remove the ECT sensor with proper care. Use sealer GM P/N 9985253 or equivalent to cover the ECT sensor threads before installing the new component while confirming the replacement components have the proper application-specific part numbers. First tighten the ECT sensor at 20 N.m (15 lb ft) then connect the ECT harness connector to the sensor. Finally, refill the cooling system. Working with the coolant sensor requires special caution because any damage will impair the system's ability to properly operate fuel control and fuel injection functions. Perform all torque specifications correctly to prevent component damage while staying alert about the necessity of thread locking compounds and lubrication materials and corrosion inhibitors or sealants that need specified use.

To service the Coolant Temperature Sensor/switch, one is needed to turn the ignition off and drain the Radiator coolant as a starting point. Carefully pull off the ect sensor shield that is encircling the ect sensor, and unplug the ect sensor electrical connector from the ect sensor and remove it from the engine. Upon installation, it is important not to destroy the engine Coolant Temperature Sensor because this would influence the operation of the fuel injection system. Mount the ect sensor into the engine and secure it with the torque of 25 nm (18 lb ft). Next, join the electrical connector to the ect sensor and wrap the ect sensor shield around it. Start the engine, fill Radiator with coolant, again check for leaks, and check the coolant and at last.

The first step when replacing an Engine Coolant Temperature sensor involves draining the cooling system until the sensor's location drops below the drainage level. Begin by removing the intake manifold cover then disconnect the engine harness electrical connector from the ECT sensor before you remove the sensor. Use GM P/N 12346004 (Canadian P/N 10953480) as sealant or equivalent before mounting your new ECT sensor with 23 N.m (17 lb ft) torque. Per the repair steps you should first refuel the cooling system then reattach the engine harness electrical connector to the ECT sensor. Finish the installation by replacing the intake manifold cover. Engine coolant temperature sensor handling requires special attention to prevent fuel injection system performance issues as well as strict adherence to application-specific part numbers and torque specifications.

In servicing the Coolant Temperature Sensor/switch (For Computer), one should first drain the Radiator coolant and disconnect the ect sensor's electrical connector. Using the 19mm deep well socket and an extension, do remove the ect sensor. Install by hand starting the ect sensor into the engine and tightening it to 30 n.m (22 lb ft). Next, plug in the electrical connector, refill the Radiator with a new coolant, start the engine and check for leaks, and check the level of the coolant, also. You must be careful when manipulating the engine coolant sensor, because the slightest damage will influence the proper working condition of the fuel injection system.

When servicing the Coolant Temperature Sensor/Switch (For Computer), before doing anything, allow the engine time to cool down to avoid large loss of coolant or personal injury. Rigorously handle the coolant sensor since damage will influence the running of the fuel control system. Start by partially draining the coolant system, discone the ECT sensor electrical connector (uncrack) as well as remove the ECT sensor. For installation, coat the threads of the sensor with a non-hardening sealer to eliminate leakage of coolants using P/N 1050805 or equivalent. Replace the ECT sensor with installed themetic one and tighten to 16-24 N.m (12-18 lb ft), reconnect ECT sensor electrical connector, and fill up the entire coolant system.

To service the Coolant Temperature Sensor/Switch (For Computer), you should give it enough time for the engine to cool and avoid the loss of coolant or injury. Inspect the coolant sensor with care, since it will damage the operation of the fuel control system. Start by draining the coolant system to some extent. Then, disconnect the ECT sensor electrical connector as well as the ECT sensor is removed. For installation, place some non-hardening sealer onto the sensor threads to enhance against leaks of coolants by using P/N 1050805 or its substitute.
