my radiator keeps losing water, when i park it i don't see any visible leaks, i checked my compression and its 210 across the board. im having to run my fan the whole time cause it never cut on. and neither of my radiator hoses are ever hard with pressure. do you guys have any suggestions of what to check first?

 

Heater core lines, I lost two at once while driving. Maybe you have air in your system so that is why you don't feel pressure so refill and bleed.
