A/C Recharging

[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

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

[joshanoya]

ya i bought this one from autozone


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

Have you drained your system of R12 yet?

[joshanoya]

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

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.

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

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

[NC325iC]

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

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.

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

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

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?

Get duracool.

I'm trying to decide whether I want to bother converting to R134, try to find some R12 or just delete the AC altogether. After driving in LA on more than one occasion, I'm more inclined to make it work.

Anyone have a guide on how to convert the system to R134?

[joshanoya]

I don't have the red or blue cap. I have the brass cap.I'll take a picture of it when I get home to show.
