Recharge AC ?

[Calevra18]

Hey everyone I have done lots of searching but have yet to come up with an answer to my questions.

I am trying to recharge my AC system BUT I don't know what freon to use R12 or R134?

I have a 1999 323is

Second when I turn on the AC it feels like it sucks a lot of power from the engine, therefore doesnt accelerate as quickly or anything, anyone know what could be causing this?

Lastly whats the highest amp alternator that can go on a 323 and where would be the best place to get one?


Thanks in advance.

Is the green circle where I am supposed to recharge the A/C?

Also the orange circle there is a cap for a substance but what is it for transmission fluid, brake fluid?



Lastly there is a strange noise coming from the back of the car, kind of likee a squealing and its more apparent in reverse then in first and second but only when I let the clutch just coast. Any idea what it might be there is a video of it posted its faint but you can here it.
sorry about the other noise we were driving on gravel




Ps I didnt take or have any copyrights to the picture.

Does the squealing noise vary in its frequency as you speed up? Does it disappear when you apply the brakes lightly?

In General the re-gas socket would normally be at the front of the engine bay as it is a maintenance issue for garages... Don't worry about the type because the latest stuff would be used anyway.
As for the squeal (which i couldn't hear)... If at the rear as you say, Could be a dry Differential or diff bearing - check fluids pal... AND check what colour it is too !

The orange circled item should be the power steering reservoir.

I believe R12 is more expensive. R12 has the tendency of leaking, So R134 eco friendly.

Since it's a 1999, it has to be an R134-A system.
