How to replace the Coolant Temperature Sensor on GMC Safari?

Begin by switching off ignition before you remove the engine cover according to the replacement procedure. The coolant drainage process needs to reach beneath the sensor position of the ECT before the electric connection gets detached while pulling the ECT sensor from its place. The threads of the new ECT sensor require application of sealer GM P/N 9985253 or equivalent which should be followed by sensor installation at 20 N.m (15 lb ft). The first step includes connecting the ECT sensor harness connector to its port before proceeding with cooling system refilling and engine cover reinstallation. Damaging the coolant sensor requires special handling since shoe damage will impact the fuel control system functions and you must use the Component Fastener Tightening Notice to achieve correct installation.
