About 2 weeks ago i installed a new heater core in the 87GT i recently purchased.... before i changed it the air fron the vents smelled heavily of antifreeze... now two weeks later the heat works perfect and the car hasnt lost a drop of anti freeze but the heat still smells ( not as bad but it isnt a pleasnt odor). is this a byproduct of the heater core leaking for a long period of time? is there any way to fix this? or do i just have to wait for it to go away?
