Default cooling system pressure

Have had some violent overflows of the cooling system at the coolant reservoir while driving. Replaced the cap and thermostat and there are no leaks. Just got done running car at idle for 30 min, fans came on ok but there is no pressure building up in the system. Took cap off after running to check and nothing. No back pressure at all. Any ideas?

Mine freaked and was spewing shortly after I changed my A/C compressor. Yours sounds like you've got a mean air pocket. You probably need to stand there while it's running and pump in more and more and more water.
