You'll see it when the thermostat opens up. If you don't see it, you have a blockage somewhere. If all is good, top off the rad and you're good to go.
The fact that you have steam coming from the engine indicates you have a leak somewhere. Find it and fix it before you go further. If you fix that and you're still overheating, then proceed in order of expense. Buy a cheap infrared thermometer and check your block and rad temps to rule out a faulty gauge. If the system has been neglected, full of rusty water, soft hoses, etc., then prepare for a long workout period where you spend a lot of money replacing parts to get it reliable again. If the system is in good order, then do a pressure test to rule out a head gasket failure. If that checks out, you're into more expensive territory. Check your compression and your oil pressure. If the engine is worn out, it will overheat no matter what. How does the car run otherwise? Does it run rough? Blow smoke? Have terrible vibrations on the road?
