Hi, My name is ***** ***** for the delay.
I will do my best to assist you.
does the cooling fan come on?
do you ever need to add coolant?
the one time you had to add coolantt,is that because it boiled out the coolant?
does coolant flow in the radiator even when it is cold?
i was thinking the thermostat may be stuck open,,this is why i wanted to know if it flowed cold.
i dont think you have a blown head gasket..
i think you may have one of two possible problems..
1-the thermostat is sticking open letting the coolant free flow[not giving the radiator time to cool the coolant]..or
2-the radiator itself is clogged on the inside[some of the core may not be flowing
replace that thermostat
you are very welcome

there is now nothing left but the head gasket,,
it is possible for the head gasket to be blown from the cylinder to the water jacket,thus casing the compression to blow into the cooling system causing the pressure to equalize stopping the coolant from moving
you ar very welcome
