quickie problem, friend's ford taurus not blowing out any hot air, coolant level is fine, has trouble keeping pressure though, its leaking near the cap but not to terrible, because its more upper, only when theres pressure and/or fluid swishing around when driving is it able to escape out of the top... Hoses are old, and probly breaking down from the inside.
I think it could be the heater core, before it worked somewhat ok, never toasty though... it went to straight cold air, then sorta worked one night... but since then it hasnt been working...
My guess is the heater core, and/or maybe a clog (no idea when it was last flushed)
I told her to just watch the engine temp, making sure it doesnt get to high...
