91 gp cooling problem

1991 gp 3.4 dohc

i replaced the intake gaskets upper and lower and the car ran great for
about 2 weeks. now i have another problem. the intake fills with air as soon as i start it up and it blocks the flow of the coolant and starts to swell the hoses. i tried to bleed the air but it fills back up right away. i took the thermostat out and it seemed to get worse. i am lost now so if anyone can help? please do



thanks to all and to GPT DAD A BIG THANKS

Sounds like you might have botched the upper intake gasket job. If theres air in there (poet and didn't know it) it's most likely that after finally seating the gasket is causing the leak. or there might be a crack in the intake. Not good.

how could air get into cooling system from there? there is no water jacket where it bolts on to the manifold
