TORC811 Posted May 6, 2014 Share Posted May 6, 2014 Sorry if this is already out there. I did a few quick google and forum searches and haven't come up with anything. A previous owner of my MJ removed the plug for the CPS and used a 1/4 nut and bolt to install a CPS. I'm in the process of installing a new one and am looking for the correct bolts. What thread and pitch do they need to be? I saw some where that they may have been special shoulder bolts. Is this correct? If so can common bolts be used?

cruiser54 Posted May 7, 2014 Share Posted May 7, 2014 Thread is 7mm X 1.0 Length from tip of threads to bottom of the bolt head is 1". Of that 1", the bottom half is obviously threads. The shoulder of the top half is 5/16" or 8mm in diameter. Link to comment Share on other sites More sharing options...

TORC811 Posted May 11, 2014 Author Share Posted May 11, 2014 I got the new CPS and plug wired in yesterday. Now to reinstall the O2 sensor connector along with a new sensor and a new knock sensor. Some people should not be allowed to work on vehicles, especially wiring! Link to comment Share on other sites More sharing options...
