No. All you need is to drain the rad, heater, *AND the block*. Make
sure
your heater is turned to full hot!!

Stick a garden hose in the rad filler neck. Close rad drain, let water
run
into rad and out of block drain until clear, then open the rad drain
until
the rad runs clear.

Open al the drains again, and let it drain. Then close all drains and
refill with new antifreeze.Your Type 2 should be premixed, so you won't

even need a bottle of distilled water.
