GPdriver1986 Posted September 29, 2003 Report Share Posted September 29, 2003 Hey guys I might be changing my 02 sensor soon and I was wondering what size of wrench I should use? I'm also going to convert my base dash to a full gages cluster so I need to change the oil pressure switch to a sender, what are the sizes of wrenches that I need?

Robby1870 Posted September 29, 2003 Report Share Posted September 29, 2003 Im pretty sure the O2 is 7/8in. Dont know about Oil sender but I would say anywhere from 5/8in to 15/16in Robby Quote Link to comment Share on other sites More sharing options...

Dont know about Oil sender but I would say anywhere from 5/8in to 15/16in Robby The oil pressure sender is over 1 1/4". I had to replace mine after an oil change that went to hell. I had to drive a couple of miles to my mechanic with a leaky oil pressure sender because the biggest open end wrench and deep socket I have is 1 1/4'. I had to pull over every 3 minutes and put in a quart of oil in. Quote Link to comment Share on other sites More sharing options...
