over heating

[armypunk1172]

hi i have a 99 grand am gt and it kinda over heats on me i only drive it for about 10 to 15 min just back and forth to work. the car heats up to about 215 and sits there then goes to about 230 then cools off drive it for more then 20 min and it over heats fast now i reaplaced the thermo stat and it still dose it now this is the thing there is air in the system so i tryed to bleed it but it never stops bubbling so i think its the intake gasket but im not shore so eny help would be appreciated thanks

Most probable cause for the bubbling is a blown up head gasket

I had this same problem...we spent almost $600.00 in just new radiator 2 thermo states new radiator fans coolent flushes and everything else immaginable....turns out that it was a cause of 2 problems at the same time my converter cloged and so did my resivour for my coolent. So that being both went out the car was over working itselfe with the converter and it was limited on coolent...talk about bad luck. but now that i have both those fixed it isnt a problem now and i can drive it for a LONG while...im still working out the converter problem but as of now my GA is ok and back on the road.

yes it only take once to overheat then you got a blown head gasket or maybe both cracked head also so have it checked with dye if your going to replace it yourself?

its a bad head gasket.the bubbling comes from the pressure in the cylinder where the leak is being pushed back into the coolant.your probably losing a lot of coolant also though you may never see any sign of this . the pressure can get dangerously high in your coolant system causing damage to it.i had 2 grandam's and they both did as you described and both got new head gaskets and intake gaskets and it solved the problem 1999 3.4l and 1995 3.1l
