Okay, I went to remove the IAC today only to find that it seems the bolts have some sort of Torx heads. Am I correct? My Torx set isn't really built for this. Do I need to go buy a set just for this job, or am I even correct in thinking they're Torx? It's hard to see even when using a mirror. Darn, but it seems on the 4.0 in a ZJ they put it back against the firewall and made it very difficult to get at. There's all kinds of stuff in the way, and I'm not in the mood to remove it.
yeah Jonathan, they are torx. The 5.2L is accessible, but on the 4.0 on my XJ and the bf's TJ we had to remove the throttle body to be able to get to the torx bolts on it. Its not too hard to remove the TB. 4 normal hex head bolts and disconnect the throttle cable. Its kind of convenient that way in the fact that since you already have the TB disassembled, you can give it a really good cleaning too!
Thanks, Haley. I might have to do it that way in the end. Either way it looks like I might have to remove other stuff to get at everything though. There are vacuum lines in the way, and I just FINALLY got my vacuum system working good. LOL I don't want to mess any of that up. It's always something.
I hope I have a nice Saturday this weekend to work on it now. It'll give me time to get it done and take my time. I hate rushing things.
One thing... I broke something. Can you tell me what it is?
While making my way to the torx bolt on the drivers side that holds the IAC in place, this thin tube snapped in two places? It looks like it is coming off of a sensor of some sort and I haven't been able to find it on an engine diagram. Can anyone identify it for me so I can replace it? It didn't interfere with my starting and driving after replacing the IAC...
If it snapped like that, I'll bet you've got a lot of other lines that are rotting and getting brittle too. May be able to save some by using petrolleum jelly on them but with a 1995 (15 years old) it may be time to do a full inspection on all of your hoses.
This thread along with the TPS thread really saved me some heartache and dollars when I first got my Grand back in August.
