puking coolant

[Biggreen96]

Ok guys needing some help and advice as where to go from here. Truck is one in sig its been puking colant last few days and I can't seem to figure out why . Changed thermostat out have checked fuel filter and its clean fuel in bowl is clear. It takes a few minutes after starting before it startes to push coolant out degas bottle.
Is it possible the sytem is air locked or could I have a blockage somewhere. Need help as this is my dd and need it to get to and from work. Thanks for any and all help.

Could be the water pump. Most water pumps will leak but my 93 f150 water pump is bad and it is pushing it out of the fill cap. I've seen some do that..

Pretty sure its not head gasket no water in oil. I'm thinking water pump also but never seen them push water back through degas bottle. Once thermostat opens it stops

There doesn't have to be water in the oil for it to be a head gasket. It all depends on where it blew out at.

Is there any way to test for a blown gasket besides pressure test ?

you can buy a kit from Napa that will tell you if there's compression gasses in the coolant

Its a head gasket, I hate to tell ya. Same thing mine did with the stage 2's and the 468.
