I have been battling a long coolant problem i was getting an annoying buzzer constantly so i replaced radiator cap, water pump, and thermostat. I have to say the buzzer has not gone off quite as much. I have burped it several times and it seems to last for about 1 day then the buzzer is going off again, i check the coolant level and it is about 1/2 pint low. I have aftermarket temp gauge and i am not overheating while buzzer is going. It seems that it only goes off when i'm stopped, but i burped it and it would buzz at stops, when i got home i popped the hood and i noticed my loss coolant is going to my overflow coolant reservoir, and bubbles/air is coming out of the overflow down tube? Please Help?

you probably have a blown coolant seal = bad news

that's it no bad hoses or anything bad overflow cap?

its going into the overflow because exhaust gasses are pushing it out of the system and thats the only exit

Are you getting white smoke out of the exhaust, especially on startup? Also, take of the rad cap (when its cool, obviously). If there are bubbles in the coolant, then your coolant seals are hosed.

it smokes a little but it always has can you drive it like this or will they blow

As long as its not smoking bad your probably ok. Just keep a VERY good eye on the temperature (getting an aftermarket gauge is a good idea) and top off the coolant every tim you drive it. As long as you don't overheat it you should be ok for a while. But start saving for a rebuild, because it could die soon. All it takes is overheating it once and its pretty much toast.

Or rusting...

As long as you drive it a lot and dont let it sit you should be ok.

why does only bubble sometime, for some reason since i've had bad coolant seals it is smoking less than it use to, it usually smokes the first start of the morning very shortly, then i park and leave work 10 hrs later no smoke wouldn't it smoke all the time if the seals were bad? why does it bubble sometime and not others?
