5.7L Vortec Oil Pressure Sending Unit, replacement how-to?

[hd_ryder]

Anyone have any tricks to getting at the 5.7L Vortec Oil Pressure Sending Unit on a '99 Tahoe?

I know a special socket tool is required, but it looks pretty difficult to get to, at the back of the engine block.

Thanks for the help.

Its a little tricky and tight... thats what she said. . Haha... if you cant get the socket in you can get a wrench to rotate the oil pressure sensor fitting to where you can get the oil pressure sensor socket in but just makw sure you mark the original location the fitting is in

Thanks for the info rockenthebowtie.
I now realize with the throttlebody intake duct off, I can lay a large piece of cardboard across the top of the engine, and can see it a bit better than looking at it from the side of the engine.
Even a mirror can help at that point.

The socket tool for the sending unit I bought at AutoZone was too long to fit over the sending unit. There was not enough room between the firewall and the sending unit. I had to remove the sending unit with pliers. I could not find a wrench that fit the shape of the sending unit. I returned the tool at AutoZone and bought the 1 terminal sending unit like the one I took off the truck. Now the oil pressure seem to be normal so far.

Nice job way to utilize all tools that are at your disposal... now those are the signs of a super tech in the rust..
