Helps with not needing to grab a half drive socket and not having to use a fat socket for a tight spot. Glad I have it and I use it every time I do a pressure sending using on a gm vehicle.

I've not even had the chance to use this, but I do know it fits the oil pressure switch. Most switches these days are part plastic/part metal. I think they made it so you had to buy one of these :P At any rate, it should be deep enough to not damage the plastic housing or put any pressure on the plastic to cause it to fracture and leak while installing. Enjoy!

Perfect tool for the oil pressure sending unit on '04 Tahoe. With this tool and a YouTube video you can do the job yourself in 30 minutes. Save yourself some money and DIY!
