Tuxing water cooled double cylinder compressor help

I have the same unit but have not seen this. Being a closed cooling system, I would suggest keeping the cap off and turn on water pump. Look into tank and observe the fluid flow into th tank. Switch on compressor while looking into tank and see if you notice any additional agitation of the coolant. It shod look the same regardless of compessor on or off. If you see a surge it could be an air leak between compressor air and cooling passages which would require disassembly. That's all I got. Keep us posted. Good luck.
