Thumbs up Questions re: A/C removal

I have started removing my a/c parts; I've removed the following thus far:

1. Suction line from blower/evaporator unit to a/c condenser
2. Receiver lines a/b
3. Discharge hose
4. Suction hose from a/c compressor to a/c condenser

I'll be removing the receiver/dryer tomorrow. The a/c compressor will be professionally removed when my Rick's Accessories pulley's/tensioners come in. My questions are as follows:

1. There are a couple of a/c relays in the under-hood fuse/relay box. Should I remove these relays?
2. Since I am "gutting the a/c system", can I remove the a/c condenser fan as well?
3. After the entire a/c system is gutted, there will be various "loose" connectors; can I simply cut these off?

Please understand that I am a novice when it comes to this type of stuff. Therefore, please don't make any jokes torwards me if you find anything funny.

Thanks in advance to all those who provide guidance.

Leave the condensor fan alone, it pulls air across 1/2 the radiator core as well.

The compressor relay can be removed.

I wouldn't cut any wiring off, just incase you need to return the car to stock. Resale on a 06 that had the AC hacked out won't be good.

I hope you had the AC sytem evacuated insted of opening the system and letting the R134a escape, which is illegal to do.

Thanks for your concern, and please let me reassure you that I am not one of those dumbshits that would do something stupid like that. I took my S to a local dealership and paid them $90 to discharge the freon properly.

r134a is perfectly legal to discharge into the air, its R12 that is illegal to do so.

The fan comes on when the compressor is on, and since you are removing the compressor, you could take out the fan.

Several "techs" have told me that the a/c compressor fan engages when the radiator fan isn't providing enough cooling. So, it is functional, and desired, even though the rest of the a/c components have been removed.

My intent is to eventually go with a Koyo radiator, and at that time I'll go with some aftermarket fans as well.

No, it's still illegal to knowingly discharge R134 without recovering it. Every ASE refrigerant/recovery liscense test asks the question. It's also illegal to charge a known leaking system and let the car leave a shop.

Look here: http://www.ase.com/Template.cfm?Section=AS...tentDisplay.cfm


A quote from ASE:
The deadline for mandatory recovery of R-134a was November 1995. After that date, venting of R-134a became illegal. Recycling of R-134a, using EPA-approved equipment, became mandatory on January29, 1998.

There are 2 fans on the radiator, both pull air across the core. 1 is called the condensor fan, 1 the radiator fan. Both are used for engine cooling, and both are used with the AC.

If you drive the car in traffic where you can't count on always having a air supply blowing over the radiator (like a track only car) It's safest to leave both fans.
