RE: 01' DII Coolant Flush
D2's were no ment to be flushed, drained and filled only by removing the hoses at the T/stat.
MMake sure you bleed all the air from the system when your done so you don't over your engine.

And once you realize what a near imp[ossible process this is, remove and drain from the old t/stat, installing a new one when done, fill and bleed the system and rebleed it a day later.
