mmmmmmmm they are really hard to replace but most likelly is goin to be a intake gasket, i do recomend you to call arrown the auto repairs and ask for a pressure test to the cooling system
this test is not that expensive and will tell you exactly where is the leak coming from, but on this type of vehicles i badly see a freeze plug leaking.

start the enginemake sure the radiator is full with the cap oon tightly and open the hood and let the car idle in the driveway untl it starts to team, this way you can locate where the steam is actually coming from.
when it is overheating is there white smoke coming out of the tail pipe?
if there is this is a good sign thatyou have a blown ead gasket.
the other thing that couldbe causing this over heating is a plugged catalytic converte.
to rule out whether it is the themostat sticking or not. remove the thermostat from the car put it in a pot of boiling water on the kitchen stove and see if it opens or not. the boiling water will make the thermostat open if it is working properley. Be sure to pay attention as to which way the thermostat is pointing when you remove it so when you put it or a new one back in that it is facing the correct direction. if it is not facing the rite direction it will not open and cause the car to over heat.

you should have power on the tan wire for about 5 seconds with key on try to cycle key on for 5 sec off for 10 sec if no power chehave power on both sides of fuseck ecm 1 10 amp fuse if you check ecm b fuse if that is ok check for power on the orange wire and power on the green with white wire on fuel pump relay if you have power on those check for power on the grey wire out to fuel pump if you have power on grey wire you have a bad wire from the grey to the tan wire some where in the harness hope this helps

i would try to flush the cooling system completely
if I had to guess someone put stop leak in it when the freeze plug started leaking
also check the oil to make sure there is no water in the oil
