Default Need help with AC line

Long story short I was installing the grimmspeed master cylinder brace and messed up.

Instead of removing the 10mm ac line bracket bolt, I loosened the AC line and it discharged my r134a refrigerant.

I then went to retighten it and i could still hear it hissing, continued to tighten and then I thought I stripped it. There are 2 crush washers so I hope it was that.

Does anyone know what part this is in case I need to replace it. It's the box that AC lines go to (coming from above tmic) and from (towards radiator) next to the drivers strut tower wall.

Just want to be clear, my apologies for being a noob

Mike

ouch. hopefully you didnt get any freeon on your body! a picture would help. but from what you are saying, it seems like your AC line is fine. seems like u maybe stripped either the AC compressor where the line goes in, or the firewall. if thats the case, youre looking at a tapping or heli coiling the damaged part. GL!

Edit: OP read my mind and added pic before i finished this post. LOL

The bolt that I potentially stripped runs into the AC line bracket which items onto the strut tower wall by another bolt

Anyone else have any thoughts?

OP can be more informative. Your questions are pretty vague. What side is it on? high or low? what type of bolt is it? hex bolt? when you say on the strut tower wall, what exactly do you mean? on fender side wall? or firewall?

Maybe more pics of different angle? Because if you are talking about loosing psi where you loosened the bolt, then you are talking about a connection, either at condensor, compressor, evaporator, firewall. all the other bolts IIRC are mounting bolts to the chassis. they run through tab like brackets.

GOod luck bro! Ive redone the AC in my car twice. lol. no fun

Can you try taking a picture with higher resolution? A/C refill isn't hard. If you stripped the mounting bolt, you can just retap it and helicoil or time-sert it. You will probably need to rebuild the compressor to get all the metal shavings out of it.

The banjo bolts and washers are not reusable - the bolt will stretch when you tighten it the first time, so when you loosen it and re-tighten it, it will no longer seal correctly. Buy new ones.

Good luck, let me know if you need help. I'm EPA certified to do A/C
