Worked great. My pressure gauge back showing. Got to fish out that little filter. I used a piece of wire made a hook

As many have stated, this sensor is a bit of a Kam*ala to get in and out of a 5.3L GM engine. But it is do-able, if you can work by feel and if you can change a spark plug, you can save yourself about $300 by doing it yourself. Getting the old one out was more of a challenge than putting this replacement part in. Once I had the old one out, it was a piece of cake to drop this one into place and get it tightened down. You will have to procure a 1-1/16 inch or 27 mm deep socket and a few extensions and a u-joint type adapter to pull this off. I used one from Hotel Foxtrot rather than the ones available here because HF is cheaper, and in any event was not hard other than that part about leaning up over your engine compartment. I just used a patio chair pad and an old rug to keep from scratching my paint, etc. and it was no problem. I am 6'3, you will need a tall footstool for this gig. I only removed the plastic vortex cover from the engine. Some videos recommend you remove other parts, but I did not need to. Just took a little time and patience, and saved me several hundred dollars by DIY. Lots of videos on YouTube to watch to bolster your confidence before you take the plunge. But eminently doable by anyone who is comfortable changing their own oil or changing a spark plug or similar light work. My oil pressure was reading almost 80 PSI whether the engine was running or not, so after watching some YouTube decided the sensor was probably the issue. Replaced it and now it's working perfectly. I can't speak to longevity yet of this product but if it fails, I will post an update. Hope this helps you.

Nice quality oil pressure switch! Easy to install, and a great affordable price. Fit on a 2005 Chevy avalanche 1500z71 5.3L truck. Overall a happy customer!!😁

Worked perfectly. Installed it in my 2003 Suburban 5.3 Vortec. Its a pain to install but that has nothing to do with the sensor itself, just the location in the engine bay. Word of advice make sure you get a oil pressure sensor specific socket and it helps if you disconnect the fuel lines to access the part of the bay where the sensor is located.

I purchased this for my 2005 Chevy trailblazer.At present it has been working well. It was a good price for which I paid for it. I would recommend this.

High quality great fit

This thing turned a 5 minute job into a 4 hour job. Since it’s aluminum it sucks. When I started tightening it down after removing the old, I started by hand tightening and then used my torque wrench with 15lbs pressure. After just a couple turns (not even halfway in there) it sheared clean flush with the block. So then I had to figure out how to remove it and ended up getting super lucky with an easy out. But being aluminum I couldn’t even clean any shavings out of the block with a magnet (luckily I had very few). Don’t buy this!! Just get a quality steel one from your local legit parts store.

Needs a oil pressure sensor socket. Its a 26mm or something big.But perfect tho. Accurate reading. Very happy with it.
