The first time i drove the car it ran great but i noticed steam coming from below the carburetor and a hiss sound, and when i drove it with the cap off it did neither of these things and i saw no steam or smoke. Here is the update: Ok I drove the car with the radiator cap off and the radiator appeared to be empty. As to if the Water Pump is leaking, i dont know, not sure if it is from that. I did add 3/4 a gallon of water the radiator took it all and i saw no smoke or steam with the cap off, except for a small amount when the car was turned off, and i saw the water level at halfway in the radiator.

Maybe the radiator was empty the first time and that is why i saw steam?

Is a Pressure Test the best thing i can do, or get antifreeze now since i added distilled water and fill it up and see if it returns? And if Pressure test, HOW?

Also, my temperature and oil pressure gauges domt workl OR i cant see them. How do i check on that?
