Re: bmw e32 750il AC LEAK

The system must not leak. Pulling a vacuum and using soap and bubbles will not work. Put some refrigerant in the system and use an electric sniffer to find the leak .I suspect you compressor shaft seal is bad/leaking due to the system not working for such a long time but this is only a guess. The re...

Re: Expansion valve

Your best bet on finding one is the second hand market. Trying to source a brand new one for such an old vehicle will likely yield poorly assembled, and who knows what's inside the power head (=how much oil it returns to the compressor in critical operating conditions), Chinese garbage. So what wou...

Spray a water hose on the condenser when the pressures are high. Does it drop like a rock?
