Short video briefly describing a method of tools used to be able to reach down into the valley of this 3.6 engine to remove and replace the temperature sensor that is commonly an issue on the chevy Colorado of these model years.
Check the thermostat housing assembly first. My 2018 colorado zr2 is running the fan afterwards for five minutes or so. Im not taking the risk and replacing thermostat housing with O-ring and temp sensor. AC delco parts always check Amazon hella cheap! My local advance auto parts, o’reíllys and auto zone failed me could not get the parts. And Chevy dealership over price parts to expensive.
There should be a white small tab you have to pull up with a long angled pick then you can try long needle nose pliers to gently grab the connector and it should pull off
I just did this job on mine. I don't see how that would even work. The sensor is at an angle and is so close to the engine that there was no way to get a socket extension in there.
