I'm not sure what this is but it is clicking something fierce when my engine its running...4.0 H.O. I6 99xj...if anyone has any advise or knowledge on this thing feel free to voice an opinion....also I will probably use this thread again on account of I'm not wicked familiar with engines yet...but I doooo love my straight 6 )

 

Purge solenoid. The noise is normal.

 

Ty much ....without having looked it up yet, I'm assuming its to do with tge evap system?

 

Yup, evap purge. Imagine how loud it would be if it wasn't rubber isolated.

 

Yeah no kidding, I just think its weird I havent heard it before now, I have been under the hood a bunch...lol I mean..it is an xj )

 

check lines on it maybe ones brooke/disconected

 

Will do, as soon as the weather lets me

 

Lines look good tough to say, seems not to be bothering anything)

 

This is some sort of sensor connected to the battery tray...why? Its got a slightly mushed wire and I want to know if I should be replacing it...and if its affecting my intermittent start issue.....just put new terminals, sanded side ground strap and firewall ground strap, bench tested alt, passed, brushed and greesed connections for alt too...gonna try to start it now...maybe adjust nss too...

 

Battery temp sensor, it tells the ECM how hot the battery is so it can regulate the charging system rate to keep from over charging the battery.

 

Thank you....starts great now.....now onto the womans jeep )
