    Default 1997 Legacy 2.2L Radiator mystery tubes

    My daughter has a 1997 Legacy 2.2L, 5 speed, and it has begun recently to
    overheat, but only rarely. I looked at it, and found the reservoir tank
    dry, and no coolant in the radiator. Also noticed two brass tubes coming
    out of the side of the radiator on the same side as the radiator cap. These
    tubes are not connected to anything. What are they for? Could their lack
    of connection to anything be contributing to overheating? I can't believe
    the car has run at normal temperatures for quite some time if those tubes go
    directly into the radiator coolant!

    Thanks.

    - Phil

    Your description makes me think that your radiator has the connections
    for the auto tranny fluid cooling circuit. Is this an original or
    aftermarket radiator?

    For the overheating, look for the usual culprits:
    Electric fans not working
    Defective thermostat
    Defective radiator cap
    Clogged radiator fins
    Clogged coolant system
    Defective coolant temp sensor
    Trapped air in the coolant circuit
    Crushed exhaust pipe
    etc etc
