How to replace the Coolant Temperature Sensor on 2004 Buick Park Avenue?

To get ready for replacing the ECT sensor, drain the coolant so that it doesn't reach the sensor after you've switched off the ignition. Take off the connector from the sensor and gently pull the sensor out. Put GM P/N 9985253 sealer or equivalent on the threads of the new ECT sensor, making sure the part number matches your vehicle's requirement. There are components in the job steps that say if a lubricant, sealant, or compound is required, and sometimes these items are given a coating before use; Only use these coatings if it is specified, since they can change the final torque and the component's performance. Make sure the ECT sensor is tightened to 20 N.m (15 lb ft), plug in the ECT harness connector, and finish by filling the cooling system.
