Re: Prestone leeching

  I like to disconnect the upper radiator hose and insert
  a garden hose into the rad. Then run the engine 'till
  you get nice, clean water from the disconnected hose.
  This way you are sure to flush all the old crap out from
  all those impossible-to-drain nooks and crannies.
  Also, on TQCs and 4KQs anyway, there is a plug
  in the top of the radiator that can be removed with
  the engine running to eliminate any air trapped inside.
