How to disconnect A/C lines at condenser

  • 166 MILES
I'm going to replace the radiator in a 05 Grand AM, 3.4L
I read that the radiator/condenser and fan all come out together thru the bottom.
Is this true or can I cheat and remove it without disconnecting a/c?

If true then,
I need to disconnect the lines at the condenser and im not sure how they come apart. It doesnt have the traditional fitting on the line, it has a nut and then a star head bolt. My question is, do I remove the nut first, then the star head bolt? I know it sounds stupid, just want to ask before I do it so I dont damage it.
Also, does it have the traditional o ring or is there a different gasket I need to get?

Yes, i'm getting the refrigerant recovered first?

And, I figure to lose only about a 1/2 qt of trans fluid, can I just add that thru the red cap at the top or do I need to jump thru all the hoops and use the fill hole on the side?

Sum up
1)How to disconnect lines at condenser?
2)what type gasket or oring is used?
3)how to add trans fluid?

I asked if it has an o ring or gasket and you told me it has an oring or gasket.I know that much but which one?

It has a nut and also a bolt. Do I just remove the nut or nut first then bolt. Looks like just nut, just want to be sure.

I removed the nut and the line separated, no problem.
Replaced the O RINGS, lubed 'em with PAG oil, no problem.

R & R'd the Radiator, no problem.
I applied all techniques and observations while doing this, I might add.

Topped off the transmission fluid with the approx amount lost, no problem.

Took it back to the shop to have the system properly charged and they charged it using proper techniques and observations. My repair was fine, no leaks.

I worked on cars for many years, retired now.

And can I just add some trans fluid in the small amount I lost without having to go thru the BS of jacking it up level, taking out the plug, etc etc etc

Thanks in advance for any and all info

Do you
