FYI Here is text from e-mail I rec'd yesterday when I asked Subaru what recalls applied to 2000 Legacy GT (sedan):
"I noticed that our computer system reflects two open recalls. They are 1)WWP99 ENGINE COOLING SYSTEM CONDITIONER & 2)WXV79 ENGINE CONTROL MODULE.
Here is some brief background regarding these campaigns.
1)Subaru of America,Inc. (SOA) has determined that over time, affected vehicles may develop small external coolant seepage from one of the engine cylinder head gaskets. This is the result of normal expansion and contraction of engine components caused by the heating and cooling of these parts. To prevent cylinder head gasket leaks from developing or to correct an existing leak, a special Subaru Engine Cooling System Conditioner should be added to the vehicle cooling system.
This Service Program affects most vehicles from the 1999 through the 2002 model years. As this program affects many vehicles, we are staging the distribution of these letters starting with the 1999 model year vehicles. Because of the large amount of affected vehicles, we are asking later model year vehicle owners to wait till they receive the official notices.
However, if you are experiencing any problems related to this situation, please
contact your local Subaru dealer to schedule an appointment. If not, we would ask you to wait until you have received your letter, which should ensure that there is enough inventory of the conditioner on-hand at the dealership for those vehicles experiencing this condition.
2)Subaru of America, Inc. (SOA) has determined that affected vehicles, may
experience a broken wire on an integrated circuit within the ECM. Should this
occur prior to replacement, the CHECK ENGINE warning light / Malfunction
Indicator Lamp (MIL) will illuminate steadily while the engine is running
advising the driver of a malfunction and the need to seek repair service."
