First time locating this sensor? It can be tricky! Just take your time and you’ll get it. Would recommend checking youtube too for video tutorials.
That’s a good suggestion about youtube! Sometimes seeing someone go through the process can make all the difference.
Honestly, it’s like a scavenger hunt under the hood! Just gotta follow the coolant lines.
I love the comparison to a scavenger hunt! 
But seriously, patience is key. And don’t hesitate to ask a friend to help if you need another set of hands.
My friend did this repair without knowing about the sensor’s location. Ended up causing more work! 
A tutorial would definitely help those who are less experienced.

That’s unfortunate! A comprehensive guide could prevent these mishaps and save some headaches.
Reflecting on how vital it is to share knowledge like this. For anyone wanting to dive into this repair themselves, knowing where the sensor is can save time and money.
The coolant temp sensor on a 2015 Tahoe is located near the thermostat housing. It’s typically on the right side of the engine block. If your gauge is acting up, it could be a sign of a failing sensor.
That’s good to know! What are some signs that the sensor might be failing?
Common signs include fluctuating temperature readings and your check engine light coming on. If you notice your Tahoe overheating, it might be a malfunctioning sensor.
I had the overheating issue once, it was super frustrating! How did you troubleshoot it?
First, I checked the sensor wiring for any damage. Then I tested the sensor’s resistance with a multimeter. If the readings were off, I knew it was time to replace it.
Great tips! Can anyone share how difficult it is to replace the sensor? Is it a DIY job?

I love that it can be a DIY job! What tools do I need, specifically?
You mainly need a socket set, a torque wrench, and some safety gloves. Don’t forget a new gasket for the sensor too! Safety first!

So, a few basic tools then! This is sounding more fun than I thought. Anyone installed aftermarket sensors?
I have! They can be hit or miss, but many work just as well as OEM. Just be cautious and do your research on brands.
That’s good to know, I like saving money! Any recommendations for reliable brands?
AC Delco is usually a safe bet for our vehicles. They’re OEM quality, so it’s a good investment in the long run.
