Exact Fit Genuine GM part!
Exact fit Genuine GM part. Even for a rookie this was a simple part to replace. Get a 19mm Deep Socket and it’s so easy to remove and replace. Use a pick to unlock the wiring harness (hardest part) and it won’t take more than than 30 mins. Also disconnect the negative terminal on the battery and the codes should clear. You’ll save a ton DIY vs a dealer. Watch a video to see where it’s at - just left if Dipstick on my Acadia. It’s Easy!!

Buy AC Delco if you still have code popping
Bought a Car Quest brand sensor before this one and regret not buying AC Delco for it. Replaced the Car Quest twice b/c it would pop code after a mile and sometimes as soon as I started it (A/C off and temp gauge not working). I got tired of pulling the battery terminal to reset the code so I decided to just go with genuine parts after dealing with it for months. It fixed it the first time. No real rhyme or reason but it must be b/c it was AC Delco. If you are still having problems just buy OEM for it. The real kicker was the Car Quest sensor was $34 from Advance Auto. I could have saved time and money if I just bought this one. Another side note: The other sensor had a different size MM head, don't remember what it was but it was larger and barely fit b/c the socket was bigger.

USPS two thumbs down.
I can only imagine that it’s a good product. If only it was really in my mailbox like the package tracker says. I can’t argue with the post office. They’ll say it’s been delivered to the correct address. Then pull my address up on google maps (aka their tracking app) and show me my house. This is why I have a Ring doorbell. I’ve been through that once already.I really needed it when I ordered it. It’s 94 degrees and I have a 4 month old and a 4 year old. My AC will not work when my temp gauge reads incorrectly.I can order another one and it will still be cheaper than buying from a local parts store.I wish UPS or FedEx were exclusively delivering for Amazon. I’ll order another. I’ll update my review if it’s any good.It came in the mail today. Not bad to install. I used a 3/4 spark plug socket with the rubber pulled out to remove it. It appears to be working. It looks just like the one that I removed.

Installed at the Dealership. I got it to install myself but found out they would do it while doing some other work and would even register it for the warranty (YMMV but I have an awesome dealer). The AC works again, so happy wife, happy life!
