First, shut off the ignition, then drain the coolant so it's below the level of the ECT sensor. Take off the ECT sensor connector and then remove the sensor in a gentle manner. Put some GM P/N 9985253 sealer or a similar substitute on the threads before you install the ECT sensor and tighten it to 20 N.m (15 lb ft).
