🚗 213-1551 GM Heated Oxygen Sensor - Authentic GM Genuine Parts Review

This is an ACDelco oxygen sensor that works great. Be wary of cheaper aftermarket products. I work on a lot of cars and it seems that if aftermarket oxygen sensors work at all, they don't work as well or as long as established brands. I trust ACDelco products.

The company sent me an updated version which is thicker and different from the original which I didn't know had been out of service within 4 months and didn't know I had a one year warranty had they didn't list it. I had to buy a new one and fall back on the smaller version. Do not install the updated version, it will not work on Trailblazers.

Replaced my worn out factory oxygen sensor with a new ACDelco sensor. My factory sensor lasted about 140,000 before it went "lazy" and I expect this one to last just as long. Fits exactly as factory as it is likely the same sensor that came with the car. Spend a few bucks more on this ACDelco sensor, not replacement brands. It is great!

I wasn't sure if I needed to replace the O2 sensors but I did it anyway because I bought a used SUV and I'm having issues with emissions. I looked at several brands of sensors and based on the reviews I decided to go with OEM as my car consists mostly of Acdelco parts. I like to buy some parts from unknown manufacturers, but I buy important parts properly. The upper current was not difficult to remove or install when the engine is a bit warm and there is a socket for oxygen sensors.

This wasn't an exact replacement for a dual sensor, but it seems to work great. This sensor comes in a row, one sensor, one position on a groundbreaking 2003 straight-six engine. The old sensor didn't come out initially so I sprayed PB Blaster and let the engine warm up for 5 minutes to try again, got out immediately. The previous sensor lasted 140,000 miles, although sensors should be replaced every 50,000 miles. Until then I will update the sensor error information.

This product only lasted about 11 months before failing. There are pictures showing a 2 year warranty but please do not be fooled as they do not represent the actual warranty, just a cheap gimmick to trick you into buying the product. The so-called "real" guarantee is only 12 months or 10,000 miles. I tried opening a claim with them and they did not replace the item and I had 1 year and 2-3 days from receiving the O2 sensor. I was busy with work and school and didn't have much time so I…
