I have an '03 cav with the 2.2 ecotec. i just bought an electronic oil pressure gauge and all the plumbing and fittings to hook it up but i have a problem. i do not know how to remove the old oil pressure sensor. i can't really see it so i can't tell what size of wrench it takes or how to even get to it to remove it. does anyone here know how to remove it or of any other locations to plumb the gauge into?

thanks

patrick

You dont touch the stock oil pressure sender... there is a plug at rear of the head on the drivers side (allen/torx head if I remember correctly) that you remove and install an autometer #2277 M12.5->1/8th NPT fitting, then the autometer pressure sender, and wire it all up.

You want the rearmost plug, on my motor it was covered by a a grounding strap.

What I did on my 04 Cavi. is this...removed the stock sender and machined a custom fitting to go into the hole for the stock sender. Then put both the stock and the custom sender on their...picture is below.
