A couple days ago i changed my thermostat because my car wasn't warming up properly(it was like that for awhile). Everything went fine, i bled the system of air, and took it for a drive everything was fine it warmed up properly and i finally had some nice heat. I didnt drive it for a day or two and last night i was drivin' it and i noticed some steam coming out from under my hood, a little bit was coming out of the radiator cap and the overflow was almost empty. The cap wasnt holding any pressure, so i got a new one. I bled it again and drove around for while and i noticed more steam but it wasnt from the cap, i couldnt tell where it was coming, the radiator was just steaming from the passanger side, and i noticed the lower radiator house isnt getting warm its staying cold and even after i drive it around its still cold. I can drive it around it doesnt over heat it just keeps steaming and its not hold pressure i can just take the cap off after driving. anyone any any ideas whats wrong with it??? i did searches but canme up with nothing helpful

 

whats up man did u check the radiator to see if its leaking. the radiator might have a small leak look for green spots on the radiator

 

didnt see any spots...its just steaming .
