Hi everyone!

I was trying to recharge the a/c in my wife's 2009 Mercedes Benz C300 and when I tried figuring out where the low pressure service port to recharge the a/c, I was stumped. I'm only use to working on Hondas and Toyotas, so the Benz engine bay is new to me. Please help me in locating the low pressure service port.

I'm not sure if it is the one one near the top or the one near the blue washer fluid cap. Please see both pics.

Thank you so much!

I've never had to do this on my C but it's usually the thicker pipe. Sometimes it's even labeled "L" for low and "H" for high.

It's really pretty foolproof anyway because the hose from the recharge kit won't fit on the high pressure port.

Pretty much what he said in bold. So in this case it will be the port closest to the strut and brake fluid reservoir.

Thanks to you both! I'll try it out tonight.
