what does the exhaust look like ? look under the oil fill cap what do you see ? The engine won't run right without the thermostat, never use any sealers for blown head gaskets or coolant leaks , the motor is toast if it's the head gasket , there's so much crap in the motor now replacing the gasket will be the beginning of a money pit
Instant over heating could be a stuck thermostat or leaking head gaskets.
Also check cooling fans are running, and then check water pump is working, if it can't move enough coolant it'll overheat quickly.
