Recharge Kit

Where is the port side lower compared to 2002 BMW 325i? Looking to recharge the coolant.?

I found one port, but the tap from the kit does not recharge. I fear he is on the wrong side. The port I can find is just left of the fan shroud and is easily accessible. Where can I locate the low side port to recharge the system? This is not a US / Metric thing, is it? Because the valve does not fit, I wondered. THANK YOU!

You mean that you are looking to recharge the refrigerant - No coolant, I hope. The port you've tried is the port at high pressure (near the front) - so it is not appropriate. It is designed so that nobody could accidentally put the R134a in the wrong side of the system. The low pressure port you need is near the windshield on the passenger side. It has the same black plastic cover that wearing high pressure, but the port size is smaller and would fit absorber R134a that you have purchased. Be careful not to overload. A metal box with a gauge is the best kind. Follow the instructions on the container and manometer.
