You probably have a bad head gasket or a cracked head. I recommend not driving it until it is fixed. You could do further damage the more you drive it.

on my 98 Bravada there is a flap under the car where the oil filter is. I took mine off and on the passenger side of the radiator, theres a green radiator plug. On mine you turn the plug and pull it out a little.
If you personally changed it, I would guess theres some air bubbles blocking the hoses.
