So far so good on my 08 Silverado1500 5.3L V8. My oil pressure gauge dropped to zero out of no where one day and my engine light came on shortly after and this fixed the issue. This sensor is kind of a pain in the a** to get out, but it’s not terrible with the right stuff, and it’s pretty easy to install. Getting the sensor out can absolutely be done without removing ANYTHING. Yes, anything. I mean, the top engine cover needs to be removed, but I wouldn’t call that laborious. Took about 45 minutes to an hour and most of that time was spent trying different extensions, sockets and angles. I’ll post a few pictures with what I used and hopefully it’ll save someone some time. There’s a bunch of YouTube videos explaining all the stuff you have to remove before removing the sensor, but it’s not necessary. A little patience, a comfortable position, a couple attachments and you’re good to go. I used a 1/2” drive ratchet, two 5” extensions, a swivel socket adapter, a 1-1/16” deep socket (27mm should work too) and a pick to remove the screen under the oil sensor. In one of the pictures you’ll notice one of the 5” extensions has more of a rounded tip. That one I slid into the swivel adapter and that allowed for more play and a sharper angle/more room to use the ratchet. You’ll understand if you use my setup. The other extension has a square tip and that one attached to the ratchet. It worked great. Also, all the blogs and videos stated that you HAD to is a 6-point socket. This is not true. I used a 12-point and it worked just fine. Sorry for the long review but doing it this way will make all of those oil pressure sensor replacement videos seem useless lol.

Worked good

Fits perfectly as described excellent seller

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.

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.
