97 2.5 Outback DOHC
Fans work, thermostat seems to function. The fan/fans kick in and the thermostat opens drawing fluid into rad.
The problem is that the overflow bottle overflows while driving and gradually the system loses coolant.
I have flushed the rad, bought a new Subarau rad cap, also open the system to allow air to escape to prevent an airlock.
Please tell me this is not a head gasket or combustion problem...
