Is there an easy way to determine the concentration of antifreeze in the heat exchanger? I changed antifreeze in both engines but I was not able to get all of the old mix out. The drain plugs are seized so I had to suck it out of the radiator cap and open one of the lower hoses to get the fluid out. I added a 50-50 mixture of new fluid. I wonder what is best way to verify if I now have 50-50 mixture or less in engine since old fluid mixed with new. Also I want to check I don't have leak and losing mixture out; being replaced with sea water. Does specific gravity work for antifreeze?
