Does any one know how to charge an AC. - 3000GT/Stealth International Message Center

erikm · 07-25-2008, 09:03 AM

Hi, i have been wanting to recharge my AC but i do not know which hose i should use to charge it. Should i use the thick hose or the really skinny one close to the condenser. The charge system says i should use the Low pressure hose but i think my blue caps are mixed so i dont know which hose is the high pressure or low pressure. can any one point me to the right direction?
Thanks.

I believe the hose coming out of the compressor is the high pressure hose, and the one coming out of the condenser is the low pressure hose.

low side is always on the bigger hose. If you system has air in it, you will need to evacuate it with a vacuum pump first.

If you have just your basic off the shelf charge kit, it shouldn't really even be possible to hook up to the wrong side.

But if you have to recharge it you most likely have a leak.....im having hell tracking mine down right now

dont recharge until you have the leak fixed.

Some of those cheap kits come with UV dye and a black light pen to detect the leak.

Also stay away from R-134A bottles with leak stopper added. Always better just to fix the leak and put in clean refrigerant than the risk messing up the lines further.

The low side line runs across the driver's side fender and is insulated in black foam.
