[Rafaelponce92]

Hi, I hope all of you are doing well..!!! I have a Bmw 525i 1992 E34 with M50B25 engine, I´m having problems with the bleeding of my cooling system, Few days later after I do it, the coolant level goes down, and when I open the bleed screw, the level goes up again, and if I let him like that maybe in 2 weeks or less the car overheats!!.. what is happening?? please I need your help, I hope it is not a crack in the cylinder head or a little hole in head gasket, because I do not see any presence of milky oil..... thank You!!

Possible that your hoses are stretching. Make sure you got the right collant cap too... should be flat and say 200 on it.

I'd change your radiator hoses to be on safe side.
