Just started to have cooling problems cant figure out why
I keep filling my radiator and the coolant has to be going somewhere, I did pressure test my cooling system at my second job and it was holding pressure it dropped a couple of lbs but nothing bad. Whats the possibility I have air in the system because when I broke my belt I ran it for a couple of miles then pulled over and it was empty. But I had this problem before i broke my belt coolant's dissapearing and it's got me scratchin my head. I know that gm radiators have a problem with their end tanks cracking ever so slightly. BTW I have no drippy drippy underneath the car either. How do you know if your t stat and gasket are working right? What about my water pump or radiator i'm running about 20% coolant and 80% water before it was 50 50 then i started having this problem so I dont wanna put coolant in if it keeps dissapearing. It only seem to overheat on 95 at 80mph if I let of and let it coast for a while the temp drops, also my trans just started to overheat as well could the two problems be connected because I know that the trans cooler is in the radiator. Yesterday at like mid day I was seeing trans temps of 230 degrees but when let off the temp drops. Should I flush it and put new coolant in how can I tell if I have air in the system? I think I might have a clog or rust somewhere effing up the cooling jackets in the heads etc etc.

Ok I think I might have gotten all the air out, I opened the cap and the radiator was full which the past few times a while back when i did it was empty, How much air might i have had in there?

it was overfilled the other night now i dont know how full it is when i cracked the cap last night the overflow started to well overflow out of the cap. but when i looked at it tonight after work i think it was back to the level where it was supposed to be.

could it be because i ran it dry one day by accident not realizing i had run out of coolant? And another time on 95 when i broke a belt and decided to keep driving. I think it's fixed now because like i said i came out of work and popped the rad cap and it was full and 10 minutes later i pulled over and checked again and it was full the only problem is i'm 20/80 now I'm more water then coolant.
