Engine Temperature Sensor Replacement

This video will help you replace the engine coolant temperature sensor. The video is showing a 2017 Suburban, but the procedure is similar for many year and models of Chevy, Cadillac, and GMC SUVs and pickup trucks. Most relevant are 2015 - 2020 Suburban, Tahoe, Yukon, Escalade, Silverado, and Sierra.
Make sure you confirm that the temperature sensor is the bad component and not the thermostat. See the following video to help you isolate between the two:

My follow up to sensor replacement. Author of the video is correct in tools needed, Just completed my sensor replacement 6 Apr 24. Be sure to d/c the battery as it clears the computer memory from kicking the fans on to full blast. My part for 2016 Tahoe LTZ 4x4 was 15.00 bucks at O'Rielleys. A screw driver and needle nose pliers work best 4 my unlocking sensor clip. Finger on sensor hole is a must. System is under pressure. Be sure engine is COLD!! and place wrag around sensor base. I used index finger tip pressure to finalize seating the new sensor. Make sure lock tabs face front of engine before connecting the wiring connection. Secure all components and engine area is clear of tools and battery negative cable is tight before starting engine. Start engine and check for leaks and monitor temp Gauge. You might notice a slight change in where it was sitting before sensor replacement. That's an indication that it received the electrical current to operate. Good Luck.... this Video was a great help to myself and should be to you also. Good Luck.

Sensor part number for 2016 Tahoe 5.3 engine TX89 at O'Rielley's about 15.00. That's what I paid. May fit a year range of 2014 to 2017 at least and may be compatible for those year models of GM Yukon's, Sierras, and Silverado with same engines. Check and verify to be sure though.

Really not a complicated repair for DIY and the money saved is probably HUGE.

What are the repercussions if I broke the tab when pulling wire connector off. It won’t click back into place anymore
