360 Depleting air conditioning coolant

Well, it's illegal if that matters at all but so are 1000 other things DIY mechanics do at home I guess. The proper way would be to have it evacuated under vacuum by someone with an AC machine. Doesn't take long and I don't think it costs that much to purge the system.

 

Clearly there is more to this story. Why don't you start with why you are replacing the compressor?

Evacuating the system if it is contaminated WITH ANYTHING needs to be done with the right equipment and the lines need to be properly flushed. Failing to do so will ruin the new compressor.

So the sequence is:

Evacuate the system
Pull the compressor and dryer
Flush the lines
Install the new compressor and new dryer
Tighten everything back up
Pressure test it with nitrogen
Vacuum the system for 20-30 minutes
Weigh in the correct freon charge.

 

Its going to spray all over and make a mess. Next time someone wants to put die in the AC, kill them first.

 

Most common leaks are in rubber parts and will suck themselves sealed under vacuum. Vacuum testing isn't a waste of time but its the next best thing.

Flushing will help getting that horrible die out. It will also get debris from a failed compressor or drier out. Also since so many seem to want to add oil at every service many have so much oil there is little room left for freon. Flushing will fix that too.

 

Get the system evacuated properly w AC machine. I just replaced AC systems on three cars with varying "level" of needed new parts.

I am not sure about the 360 but the F430 and Gallardo had bags inside the driers. If the bag is black then your system is contaminated and need to replace more than the compressor and drier.

I posted where I sent my OEM compressor for rebuild and AC history here: https://www.ferrarichat.com/forum/posts/149832794/
