2005 Silverado 5.3 mine was dead for the last 4 years and leaking oil. I took a gamble on this because of price but it is going strong 3 months later. No leaks and still working. I would suggest it.

Good product. Works. On a 2007 classic Silverado, installation was challenging. Has everything to do with the poor design by GM. Part has worked well.

Perfect fit! 2003 Chevy 2500 HD 6.0 motor. You don’t need a special socket all you need is a deep 1 1/16” socket and a combination of different extensions.

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!!😁

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.

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.

Installed on a 2005 GMC Sierra 5.3 l LM7 immediately immediately lower oil pressure. And when I took it back apart to redo the cam shaft positioning sensor this oil pressure sensor was leaking through the top the sides and the connection. Poor design.And I can't get my money back

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