just got home and my right sock is pink...damn! after having a pressure test done and an oil change we could not find the culprit....what should I make of this? I stfa and found nothing..except it being a plugged evap drain tube...which could be it considering I haven't had a coolant flush in sometime now...what do you all think? note:it leaks when the car fan is off....

list of possibilities please

thanks

Pink = coolant

No question.

As the other posters are saying, sounds like the heater core. Your earlier posts referred to an oily film on the windshield too, which is consistent.

Heaters don't drop colored liquid ever, plugged drain or not, and pink is the antifreeze color for this era car. No other fluid in the car is pink.

As for the pressure testing, sounds like the testing was faulty. Per your coolant loss, you are losing fluid, so the test needs to show a leak via a pressure loss, and should not show that there isn't one. Test again if you want, but I would be pulling apart the heater box at this point and getting on with it.

Best of luck.
