I drove the car on the highway. My radiator is still full & my car sounds better, but it's still smoking and the radiator cap was cold. I'm really worried & wondering what could be wrong with my 1993 Chevy Cavalier.

Sounds like you may have blocked an intake or output.

Other than a full scale mechanical workover, maybe a flush and fill will clear it.

Liquid tungsten would be better. I've been using it for years on my rickshaw.

hi yes it needs a new radiator.

yeah, you clogged the thermostat. take it out.
