Need To Flush The Rad And Add New Coolant. Been Reading Where You Need To Burp- Bleed The Cooling System Afterwards. How Is This Done?

There's a bleeder screw on my 93. Look at the upper hose that runs to the waterpump from the passengers side of the car. You probably don't have the factory service manual but the procedure is in the owners manual as well.

Brass bleeder screw, see picture


Wrap a rag around it first so nothing drips down on the optispark. Engine running open the bleeder till AF comes out. Close bleeder and top off the system, run until thermostat opens and repeat once or twice more. Good to go.
