I have a 98 A4 Quatro 2.8 liter. Does anyone know what type of anti freeze it takes. I heard you need a specific kind? Also is it easy to flush yourself?

Your car will take the pink audi/vw coolant. A true flush will require special equipment but you can do a pretty good coolant flush by removing the lower radiator hose and draining the system.

G12 pink coolant, only place i know is wither VW or audi about $22 a gallon undiluted.
