A.I.R. removal

How had is it to get the bolts out of the manifolds to remove the A.I.R. system? I know that they are 9/16 bolts any one know what length to replace them with? The pipes have pin holes in them and the rest of the system is unhooked.

Most of the time it's not easy .

You would need to soak them for a couple of days in PB blaster. They are hollow bolts & delicate. You might tap them with a hammer a few times to try & work them loose. If you do destroy them you can always mig weld them. I have an extra set that came off of my rig & the guy just took some vise grips & cut all the tubes about an inch above the manifold & double them over then smashed them flat with the vise grips. They never leaked. seams like the lowest risk solution.

I would liberally soak them with Kroil or P'Blaster a few times a day for a couple days before even messing with them. (WD40 is a joke get real penetrating oil). If they are seriously stuck the shock treatment of an air impact wrench is best to break them free w/o breaking them off. If that's not an option, use a quality box end and smack it with a hammer. Quick, sharp initial shock is key here if they're rusted in. Applying steadily increasing initial force will promote the chances of breaking them.
I don't remember the ideal length of the 9/16"NF replacement bolts to plug the holes but use a new or renewed copper washer when installing. The new bolts just need to be long enough to seal, not bottom out. On exhaust parts that deal with high heat I use copper based anti-sieze if you ever have to remove them.
Regular grey colored anti-sieze is better than nothing but will burn up after awhile. If grey is all that's available mix in a poof of graphite powder. When the never-sieze burns off the graphite remains and aids in bolt removal after it's been cooked repeatedly.
If you have neither just buy the copper based stuff cause by the time you buy the grey stuff and a tube of lock cyl graphite powder the cost is a wash.

I was thinking about pb and a BFH I could always heat them with the burner out of one of my forges. All I know is that they need to go. I'm waiting on my new transmission pan so it's the time to get this done.

I don't know what size bolts they are, but team grand wagoneer has a full set of plugs for cheap.

I used 3/4" long bolts.

Whats the best way to get to the back bolt on the pass side? Take the heater off the firewall?

With the heater box mounted on the firewall I don't think that I can get this last one. Is it just the two bolts that hold the box to the firewall?
