Need help...Overheating!!

[CCSBD]

Today I looked down to see my temp almost in the red. When I push on the gas there is a big gush of air which I think is just the fan spinning faster when it the motor spins faster. When I turn the heat on the A/C is on and it blows cold air. All of my coolant is still there also I didnt notice at first but the degas bottle is FULL. Tried to pull the cap of to see if it was circulating and a couple turns in to it, it started coming out.

I hope this is just something like the thermostat sticking. Anyone have any ideas?

Your on the right track to start with. First put in a new stat, I think I remember that these were suppose to fail open, not sure? Second, the plastic impeller could have come off the water pump. Hope you didn’t blow a head gasket or EGR cooler. GOOD LUCK

yea I dont have a egr cooler Hopefully not headgaskets...coolant didnt come out due to puking but I think the coolant just doesnt have anywhere to go since the tstat might not be opening? Not sure...waiting on everything to cool down to start looking into it

TStat seems ok. Put it into boiling water and it opens up. Something else I noticed is that during warm up it will blow normal air but once it warms up and I turn the heat on it will blow cold air. The a/c compressor also comes on after it warms up and I turn the heat on.

Anyone have any ideas where to look next or how I can test other things like the heater core or water pump. I hope its not the water pump as I replaced it when I got headstuds done. Any input would be appreciated!
