- Use a 48-inch level to check the radiator for level.
- Use a pipe wrench to loosen the nut holding the radiator to the steam pipe.
- Lift the low end of the radiator and slip furniture pads under each foot of the radiator.
- Raise the opposite end of the radiator and set it down onto furniture pads.
- Check the radiator for level, and add or subtract more furniture-pad shims, if necessary.
- Tighten the nut to reconnect the radiator to the steam pipe.
- Unscrew the old air vent from the radiator.
- Wrap Teflon tape around the threads of a new air vent, then install the new vent onto the radiator; hand tighten it only.
