Review on ACDelco GM Original Equipment 213-4777 Engine Coolant Temperature Sensor: Reliable Performance & Accurate Readings by Brian Malith

I can only assume that this is a good product. If only it really was in my inbox like the package tracker says. I can't argue with the post office. They say they delivered to the correct address. Then pull my address on Google Maps (aka their tracking app) and show me my house. That's why I got the ring bell. I've been through this before. I needed this when ordering. It's 94 degrees and I have a 4 month old and a 4 year old. My air conditioner won't work if my temperature reading is wrong. I can order another one and it will still be cheaper than buying from a local parts store. I want UPS or FedEx to ship exclusively for Revain. I will order more. I'll update my review if it's good. It arrived in the mail today. Not bad to install. I used a 3/4 spark plug head with the rubber pulled out to remove it. It seems to work. Looks the same as the ones I removed.
