A/C Recharging

[hugh jass]

why is your system 'empty'?
assuming your system has already been retrofitted to r134 and you don't have any leaks, you need to pull a vacuum on it to get all the air out of the system prior to putting refrigerant in, otherwise your a/c will work like shit.
have you replaced your receiver dryer?

Theres only one nipple that the spout will even fit on if you test fit it with half a turn.

my system is empty. i thought late models were r134 compatible? i checked my compressor and it said something about r134 but not r12 o_0

All e30's came with R12 not R134a. You have to buy a specific retrofit kit that has new seals, valves, caps, oil, etc that allows the system to work correctly, it's not just about having a compatible compressor. I believe Pelican Parts sells the kit.

the low side is along strut tower. you may see a black cap unturn it, if there looks like a threaded tire valve then you will need to switch your system over to r134. On a R134 system the cap on the low side is usually blue.

High is red, low is blue. At least that's what on my car and I had mine converted.

That's not a retrofit kit...that's a can of refrigerant.

yeah, but if he hasnt been retrofitted he wont be able to fill it anyway. the Red and Blue caps on the 2 ports should be easily visible along the pass side fender, if they are brass caps then you cant use 134

[bmw325csi]

if you have the retro fit kit, the nipple would be by the right strut tower, on the hard a/c lines

Have you drained your system of R12 yet?

[joshanoya]

but i just dont know where the low pressure line nipple is located >.<

[M5wanaB]

what are you recharging with? did you buy the R134a retro-fit kit?

[joshanoya]

so im trying to recharge my A/C right now and yes i have searched this forum and many other forums but none show pictures. so i was wondering if someone can provide me a picture of where the low pressure side port is. thanks in advance
