    Heater Core Mystery - 2004 WRX

    My car vents are blowing white smoke and some coolant has leaked on the driver's side. Just the driver's side right just to the right of the gas pedal.

    I tested the hoses going into and out of the car and they were the same temp, so it's not blocked.

    I burped the radiator.

    The air blows hot.

    I'm confused because there is no blockage and it blows hot.

    Anything else I should check before taking to the shop?

    I can't pull the dash myself and its probably $1000+ all in.

    Thx

    -No modifications
    -230,000 miles
    -Radiator replaced @ 180k miles
    -A/C not functional since 200k miles, belt has been removed (I don't think it's related)

    Definitely sounds like your heater core is leaking. On my old Camero I had a bad heater core and it was blowing white smoke out the vents.
