1993 Acclaim auto trans 60,000 miles 4 cyclinder. Over heats allmost imediatly after starting. Much smoke coming out of the tail pipe. Very strong anti Freeze smell. Was a half gallon low and filled it up. No antifreeze lost but since then, but still over heating and smoking. What could be wrong. If it was a thermostat would it be smoking so badly.

Sounds like the headgasket is blown and coolant is being burned in the combustion chamber. Do below

Have it block and pressure tested-do the block first to pinpoint a combustion leaking into the cooling system or a gas analyzer to sniff for hydrocarbons at the radiator fill neck.

Pressure test: do not do a pressure test if there's leakage at the headgasket this might cause coolant into the cylinders and lock it up or bend a connecting rod if cranked thereafter. The headgasket should be repaired before doing the pressure test.

If the block and pressure test passes check the following: Thermostat, Pressure test the Rad. Cap, Clogged radiator, Fan clutch, Radiator electrical fan, collaspe hoses, water pump.
