Started my 355 Engine out - AC question

I think my tech doesn't evacuate the A/C when doing my F355 major (if an AC service is not required). I vaguely recall he just leaves the compressor hanging in the air. He also leaves the rear bumper on.

Experts?

 

My understanding is as above; just tuck the compressor out of the way.

 

I would like to hear from the experts too. I had mine evacuated when I did my major, as it definitely looked like a lot of work to remove the compressor from the engine and leave it with the car.

 

You remove the freon and disconnect the lines, leaving the compressor attached to the engine. For a DIY, there are mobile AC service that will come to your place to remove the freon for a small fee. Look on Craigslist ..

 

Drive it to a shop, have them vacuum and then have them fill it up again. If the'yre decent guys, they'll do it all for a single fee. Its about £49 in the UK to have it vacuumed and then refilled.

 

Just vent it to the atmosphere. Compared to your tail pipe emissions and all the r134 that leaks out of AC system every day it will contribute next to nothing to global warming. And besides, the climate is already F'ed

Think about it. They sell millions of recharge kits over the counter. Where do you think all the R314 goes that so many cars need recharges.

Yeah, I know, I sound like an idiot, but the reality is I'm right, 100%. Of course, if you think you are going to save the planet, go for it.

 

I've also done the vent to atmosphere then crack on. Just give it a moment to clear rather than breathing it all in...

 

I bought a pump and manifold and vacuumed and filled it myself, the tools cost about the same as a single ac service and are not difficult to use. Drive the car to any a/c shop and have them reclaim the r-134a, it's super easy for them and they shouldn't charge more than a few bucks to do it.

 

This is one thing mankind has actually made progress with. There are far less a/c gasses in the atmosphere. The hole in the Ozone Layer is healing.

 

I’ve done it both ways. evac & recharge and leaving the A/C intact. In terms of engine removal it adds maybe 20 or 30 minutes of work to leave the A/C hooked-up, but I saved at least 4 hours taking the car to the A/C place (I’m not a fan of the DIY refill cans for various reasons). Next time I do the engine out, I’ll also change the dryer so will have it pumped and recharged, but if I’m not doing the dryer I’ll leave it hooked up.

There are a couple of threads out there on it, here’s one on the last time I did it that way (post #11).

"I know a guy" that did his own engine out and did exactly that

Crazy!

 

Every ac system is leaking it's coolant over time, go long enough it's empty and you don't have to leak any to atmosphere.

 

There is room for leaving it in since it has been reported that is doable. But that corner is very tight and dealing with the belts after engine is in is pretty uncomfortable. If I were you, I would disconnect the lines after (having it evac by a mobile ac person, or by disconnecting the lines and discharging it into the atmosphere).

 

I remember freon r12 as the bad stuff and all the rules and laws we have today because of it. You can't get r12 without hoop jumping but you can get 134a which is supposed to be so great even the unwashed masses can get it at the autoparts store. So wasn't 134a made because you could release it into the air and it isn't ozone destroying like r12?

The advantage of engine out is being able to work on a tidy package why complicate that with the HVAC attached? I have never done an engine out that way.
