IC removal/installation

[paanta at splatterfish.com]

All,
  I found a big hole in my '88 5ktq's intercooler last weekend.  The
bentley doesn't have any real info on replacing it.  Is it as simple as
removing the air temp sensor, inlet hose, outlet hose and unbolting
at the sides?  And removal tricks?  I'm buying a used intercooler for
$75...should I flush it out with anything before installing?
  Hopefully this will cure my very hard start, extremely low idle,
stalling, must-sit-for-2-minutes-before-restarting condition.

  TIA,
  Pat
