Oliver:
Well, it obviously has a hot spot somewhere.
First of all, you need to put a new thermostat in it. The
cooling system is engineered to operate with one, and they cost $3. So
put a new one in. I do not think this is why you are blowing steam, but
you need to get the car back to baseline. If you have not already done
so, you need to flush the old coolant out of the coolant system and
refill with a fresh 50/50 mix of water/antifreeze.
What does the temp gauge say when you are blowing steam? If you
stop the car and put a thermometer in the coolant, what temp is your
coolant?
Check your compression. A blown head gasket or cracked head can
give the symptoms you are describing. If compression is fine, and new
coolant and a new thermostat don't cure it, then you are probably
looking at removing the radiator and having it boiled out.
BTW: Why was the thermostat removed in the first place? Was it
an attempt to cure overheating? If so, then you really need to check
your compression and get your radiator serviced.
